Question Pages
Global AI API questions developers are already searching
English-first landing pages built from public Quora, Reddit, Google, and official-doc search intent. No copied community answers — just practical steps, provider links, pricing paths, region notes, and OpenAI-compatible setup guidance for global builders.
What is the best free AI API without a credit card?
Start with OpenRouter free models if you need the fastest no-card test, SiliconFlow or Zhipu if you are in China, and Qwen if you can use Alibaba Cloud credits. For a Vercel AI SDK or SaaS chatbot prototype, keep the OpenAI SDK shape and migrate to a budgeted OpenAI-compatible relay before real users depend on it.
Score 92What is the cheapest LLM API right now?
For most text and coding workloads, start with DeepSeek or Qwen for low unit cost, SiliconFlow for China-hosted open models, and OpenRouter only when routing convenience beats the markup. Self-hosting is usually cheaper only at sustained high utilization.
Score 90What is the best OpenAI-compatible API alternative?
If you want a drop-in hosted replacement, choose DeepSeek for cost, Qwen for China/coding/long context, Groq for speed, OpenRouter for model variety, and SiliconFlow or Zhipu for China-direct access. A true replacement should only require changing base_url, api_key, and model name.
Score 88Can developers in China use the Claude API?
Direct Claude API access from mainland China is usually unreliable or unavailable. For compliant production work, use an approved account/billing route where available, a legitimate API relay, or China-direct alternatives such as Qwen, DeepSeek, Zhipu, and SiliconFlow. Do not bypass platform rules or use stolen/shared keys.
Score 86How do I set up Qwen or GLM API with the OpenAI SDK?
For Qwen, use DashScope compatible mode at https://dashscope.aliyuncs.com/compatible-mode/v1. For Zhipu GLM, use https://open.bigmodel.cn/api/paas/v4. In both cases, keep the OpenAI SDK, replace base_url, api_key, and model name, then run a small smoke test.
Score 95Grok API free credits: did the xAI credits program end?
The old xAI data-sharing credit program should be treated as ended unless your xAI Console shows it today. Current Grok API credit availability is account-specific: verify credits, card requirements, and rate limits in Console before building. Run a tiny smoke test, watch real dashboard consumption, and keep DeepSeek, Qwen, Groq, or a compatible relay as fallback.
Score 91How much does the DeepSeek API cost, and is there a free tier?
DeepSeek is usually one of the lowest-cost hosted LLM APIs, but you should verify current signup credit, off-peak discounts, model prices, and billing region in the official console before production. Use it as the cost-first route, then keep Qwen, Groq, or a relay fallback for quality and uptime.
Score 94What is the cheapest LLM API for coding agents?
Start with DeepSeek for low-cost coding and agent loops, Qwen when Chinese/code/long-context quality matters, and GLM or SiliconFlow for China-direct low-cost tests. Do not choose by token price alone: measure cost per accepted code change, including retries, tool-call failures, and human fixes.
Score 90Where can I get a free AI API key for testing?
For a fast no-card test, start with OpenRouter free models, SiliconFlow, Zhipu GLM, Qwen credits, or Groq developer access. Use the free key only for validation: run one smoke prompt, check quota burn, then prepare a paid fallback before demos or production.
Score 89How do I set up Qwen API for a coding agent?
Use DashScope compatible mode with base_url=https://dashscope.aliyuncs.com/compatible-mode/v1, keep the OpenAI SDK, store DASHSCOPE_API_KEY server-side, choose a current Qwen coding-capable model, and run a small repo task before giving the agent write access.
Score 88How should I use DeepSeek API off-peak pricing to save money?
Use DeepSeek off-peak pricing only after confirming current official rates, time window, model coverage, and cache-hit rules. It helps most for batch summarization, data labeling, evals, and non-urgent agent jobs; it matters less for interactive chat where latency and availability are more important.
Score 87Is running a local LLM cheaper than using an API?
For sporadic apps, prototypes, coding agents, and low-to-medium traffic, a cheap hosted API is usually cheaper than running local GPUs. Local wins when you have high sustained utilization, strict privacy needs, existing hardware, or predictable batch workloads that can keep GPUs busy.
Score 84Is Grok API free, and is it the same as Groq API?
No — Grok is xAI’s model/API, while Groq is a fast inference provider for open models. Grok free credits must be verified in the xAI Console; Groq often offers developer limits for supported open models. If you just need free or fast testing, compare both, then add DeepSeek/Qwen fallback for cost control.
Score 91Which OpenAI-compatible API should I use for Cursor or coding agents?
Use Qwen if you need China-friendly coding and long context, DeepSeek when low-cost agent loops matter, Groq for fast open-model responses, and GLM/SiliconFlow for domestic China experiments. For Cursor, Cline/RooCode/Kilocode, OpenCode, or OpenClaw, the best setup keeps base_url, model, key, and provider mode configurable so agent tools can fail over without changing prompts.
Score 91Can you use NVIDIA NIM as a free OpenAI-compatible API?
Yes, NVIDIA Build/NIM is a strong free-test path for hosted open models with OpenAI-compatible style endpoints. Use it to validate model quality, latency, and Cursor or agent configuration, then add a paid or relay fallback before production because catalog access, quotas, and terms can change.
Score 88How do you fix GLM API Unauthorized errors?
Most GLM Unauthorized or “not working” errors come from one of five issues: the wrong API key format, a stale or missing base_url, a model name your account cannot access, an Anthropic-vs-OpenAI format mismatch, or a region/billing mismatch. Re-copy the key and endpoint from the Zhipu console, run a minimal cURL test, then configure your OpenAI-compatible client only after the raw request works.
Score 94What is the best OpenAI-compatible API for China-based developers?
Start with Qwen when you need Alibaba Cloud compatibility and large signup credits, DeepSeek when low-cost reasoning/coding is the main goal, Zhipu GLM for domestic GLM access, and SiliconFlow when you want many China-direct open models. Use a gateway only when one key, fallback routing, or overseas model access is worth the extra abstraction.
Score 93What is the best free LLM API for OpenClaw?
For OpenClaw-style agents, start with Qwen if you want large signup credits and China-friendly setup, DeepSeek if low-cost coding/reasoning matters most, Groq or NVIDIA NIM for fast free-model tests, and OpenRouter for quick model shopping. Before production, move provider settings into config, add per-agent cost telemetry, and keep one fallback endpoint ready.
Score 92Should you use an LLM gateway or direct provider APIs?
Use direct provider APIs when one or two models handle most traffic and lowest unit cost matters. Use an LLM gateway when you need one key, fallback routing, provider outage protection, centralized cost attribution, or access to several model families. The real decision is engineering cost plus failure cost plus observability, not only token markup.
Score 91Should you use Qwen or DeepSeek API for coding?
Use DeepSeek first when your main constraint is low-cost coding/reasoning per task. Use Qwen first when you need large signup credits, Alibaba Cloud compatibility, China-friendly setup, Chinese/code mixed work, or long-context experiments. For coding agents, keep both behind the same OpenAI-compatible adapter, add GLM as a third domestic fallback when useful, and route by task.
Score 90What is the best Claude Code API alternative in China?
If direct Claude access is not reliable, do not use shared or gray-market keys. For Claude Code-style workflows in China, test Qwen for coding and long context, DeepSeek for low-cost agent loops, GLM/Zhipu for domestic model fallback, and a compliant OpenAI-compatible relay when you need Claude/GPT/Gemini plus China-friendly alternatives behind one key.
Score 92What is the cheapest API for a long-running AI agent?
Do not choose by token price alone. For long-running agents, start with DeepSeek or Qwen for low-cost loops, use GLM or a free OpenAI-compatible route for light tasks, and put every agent behind budget caps, retry limits, logs, and fallback routing. The cheapest setup is the one with the lowest cost per successful task, not the lowest input-token price.
Score 89Which OpenAI-compatible API works best with RooCode, Cline, and Kilocode?
Use a provider that supports custom base_url, API key, model name, streaming, and tool-call behavior in your specific coding tool. For quick tests use OpenRouter or a no-card free route; for low-cost coding use DeepSeek or Qwen; for China-friendly fallback add GLM or SiliconFlow. If configs keep breaking, put the tools behind one compatible relay and change only the model route.
Score 94What is the best free OpenAI-compatible API without a credit card?
For the fastest no-card OpenAI SDK test, start with OpenRouter free model routes. For Next.js or Vercel AI SDK prototypes, choose a provider that only requires baseURL, apiKey, and model changes. In China, test SiliconFlow, Qwen/DashScope credits, or Zhipu GLM. Treat no-card access as a prototype path: before production, verify paid fallback, rate limits, tool calls, JSON mode, and logging.
Score 93What is the cheapest LLM API if you need fallback routing?
The cheapest reliable setup is usually a low-cost primary model such as DeepSeek, Qwen, GLM, or a free/open route, plus automatic fallback for failed tasks. Choose by cost per successful task: token price + retries + failures + engineering time. For production agents, a gateway with budget logs and fallback often beats a single ultra-cheap endpoint.
Score 91Should I set up Qwen or Zhipu GLM API first?
Start with Qwen/DashScope if you want Alibaba Cloud ecosystem, broad Qwen model coverage, and compatible-mode examples. Start with Zhipu GLM if you want a domestic GLM route with simple signup tokens and a China-friendly fallback. If your app may switch among Qwen, GLM, DeepSeek, Claude, and OpenAI-compatible models, put the provider choice behind one base_url gateway from day one.
Score 94What is the best AI API if you need cost tracking and fallback?
Use a direct provider only if one model is enough. If you need budget alerts, per-customer spend, model fallback, and one OpenAI-compatible endpoint, use a gateway layer such as OpenLLMAPI and keep DeepSeek, Qwen, GLM, OpenAI, Claude, or Gemini as routes behind it.
Score 90What should China-based developers use if Claude API is unavailable?
First check Anthropic supported countries and do not use gray-market shared keys or bypass services. For compliant development from China, test Qwen, DeepSeek, Zhipu GLM, SiliconFlow, or a legitimate OpenAI-compatible relay that can route to supported models and keep billing/key management clean.
Score 89When should you stop using free AI API credits and switch to production billing?
Use free credits for smoke tests, demos, and provider evaluation. Switch to production billing before you invite real users, run scheduled agents, store customer data, or depend on uptime. The production setup should include server-side keys, budget alerts, fallback, and cost logs.
Score 94What OpenAI-compatible API should I use for Cline, RooCode, and KiloCode?
Use a provider or gateway with a stable OpenAI-compatible base_url, explicit model names, streaming support, tool-call/JSON behavior that passes your edit-task smoke test, and predictable coding-agent pricing. Start with Qwen, DeepSeek, GLM, Groq/OpenRouter, or OpenLLMAPI when you want one key with fallback and spend logs across tools.
Score 90What is the best free OpenAI-compatible API for agents?
For agent testing, start with OpenRouter free models for the fastest no-card path, SiliconFlow or Zhipu for China-direct experiments, Qwen for large signup credits, and Groq for fast lightweight calls. Before production, move to a route with budget caps, logs, and fallback.
Score 94How do you stop an AI agent from burning API budget?
Put hard limits in the agent route before the first production run: max steps, max wall-clock time, token caps, retry caps, tool allowlists, per-user/workspace budgets, and a daily kill switch. Then measure cost per successful task, not raw token price, and escalate to fallback only after validation fails.
Score 92Can Qwen replace Claude Code as a coding API backend?
Qwen can be a practical Claude Code-style backend when your tool accepts a custom OpenAI-compatible base_url, API key, and model name. Test it first on repo reading, one-file edits, tool calls, and long-context coding tasks; keep a fallback route for large refactors or repeated failed patches.
Score 91How should I combine DeepSeek, Qwen, and GLM APIs?
Use DeepSeek for low-cost reasoning/coding benchmarks, Qwen for long-context and Alibaba ecosystem coverage, and GLM as a domestic fallback. Put them behind environment-based routing or an OpenAI-compatible gateway so failures, budgets, and model switches do not require app rewrites.
Score 92Which OpenAI-compatible API alternatives support tool calling and JSON mode?
Do not choose an OpenAI-compatible API only because /v1/chat/completions works. For production migrations, test tool calling, structured JSON output, streaming, rate-limit errors, embeddings if needed, and model-specific context limits. Use a gateway such as OpenLLMAPI when you want one base_url with fallback across Qwen, DeepSeek, GLM, OpenAI, Claude-compatible routes, and other providers.
Score 87Is it safe to use shared or resold AI API keys?
No. Shared or resold AI API keys can expose prompts, customer data, billing, account bans, and unreliable model access. Use legitimate provider keys, keep them server-side, rotate test keys, set budgets, and choose a compliant relay only when billing, logs, terms, and data handling are clear.
Score 94How do you monitor AI API cost per customer?
Emit one usage event for every LLM call with customer_id, workspace_id, feature, route, provider, model, prompt_tokens, completion_tokens, retries, latency, status, fallback route, and final outcome. Then report cost per successful task and AI gross margin by customer. If you use more than one provider, put routing behind a shared gateway so logs and budgets stay consistent.
Score 91Does the Grok API still offer free credits?
Treat Grok API free-credit claims as time-sensitive. The reliable answer is in the xAI console and official docs, not old Reddit screenshots or promo-code posts. If no current credit appears in your account, use Groq, Qwen, DeepSeek, SiliconFlow, or a routed OpenAI-compatible API for testing.
Score 92Why does the GLM API return unauthorized?
Most GLM unauthorized errors are setup or permission problems: wrong key, stale compatible base_url, model not enabled for the key, missing Authorization bearer header, quota/project mismatch, or a client still pointing at the default OpenAI endpoint. Verify with a minimal curl/SDK request before using GLM in Cline, Claude Code-style tools, chatbots, or agents.
Score 89Does DeepSeek API have a free tier, and what does it cost?
DeepSeek pricing and credit status should be verified in the official pricing page and your own console before every production decision. It can be one of the cheapest reasoning/coding routes, but cache rules, off-peak pricing, rate limits, and price changes matter more than a stale headline token price.
Score 93Which no-credit-card LLM API works with the OpenAI SDK?
Use a provider that exposes an OpenAI-compatible endpoint and lets you create a test key before billing. For the fastest prototype, test OpenRouter free routes, SiliconFlow, Zhipu GLM, Qwen credits, or Groq; before production, add budget caps and fallback behind one compatible route.
Score 91Is the Claude API available in China, and what should developers use instead?
Check Anthropic’s official supported-countries page first. If your country or billing setup is unsupported, do not use shared keys, resellers, or bypass instructions. Use compliant alternatives such as Qwen, DeepSeek, GLM, SiliconFlow, or a transparent OpenAI-compatible routing layer with clear billing and data terms.
Score 90How do DeepSeek cache and off-peak pricing affect real API cost?
DeepSeek can be extremely cheap when your workload benefits from cache hits or off-peak rules, but the real cost is the accepted-result cost after retries, invalid outputs, rate limits, and price changes. Verify current official pricing, then benchmark your own prompts before committing production traffic.
Score 91Should you use Qwen or GLM API for coding agents?
Use Qwen first when you want a broad coding-model lineup and Alibaba/DashScope compatible-mode support. Use GLM when you want a China-direct budget route with simple GLM model access. For production agents, keep both behind an OpenAI-compatible gateway so failed coding loops can fallback instead of burning time.
Score 94Can I replace OpenAI by only changing base_url?
Often yes for basic chat, but production migration needs more than a new base_url. Change base_url, api_key, and model, then test streaming, JSON output, tool calls, rate-limit errors, context length, and cost per accepted result before sending real traffic.
Score 92What is the best no-card LLM API for Vercel AI SDK?
For a quick Next.js or Vercel AI SDK prototype, start with a no-card or credit-backed OpenAI-compatible endpoint such as OpenRouter free routes, SiliconFlow, Zhipu GLM, Qwen signup credits, or Groq. Configure baseURL, apiKey, and model explicitly. Before real users depend on the chatbot, move to a route with budget caps, logs, and fallback.
Score 93What is the cheapest API for Cursor custom models?
Start with DeepSeek or Qwen for low-cost coding, add GLM or SiliconFlow as China-friendly fallbacks, and use a gateway if you want one key with spend logs and fallback. The cheapest route is the one with the lowest cost per accepted code change, not the lowest token price.
Score 90What should you use if Grok API free credits are not available?
Treat old Grok free-credit screenshots and promo posts as stale until the xAI docs and console confirm current credits for your account. If credits are unavailable, test Qwen, DeepSeek, GLM, Groq, OpenRouter free routes, or an OpenAI-compatible gateway with trial credit and budget logs.
Score 91What should a startup use when Claude API country is not supported?
Check Anthropic supported countries first, then avoid shared keys, account pools, and unsupported-region bypasses. For compliant product development, benchmark Qwen, DeepSeek, Zhipu GLM, SiliconFlow, or a legitimate OpenAI-compatible gateway with clear billing, logs, and data-handling terms.
Score 94Is DeepSeek API still cheapest if pricing changes?
DeepSeek can be a strong low-cost route, but do not rely on stale screenshots. Check official pricing, then calculate cache hits, cache misses, off-peak windows, retries, and failed outputs. For production agents, add Qwen, GLM, or gateway fallback.
Score 92How do you fix Qwen or GLM unauthorized errors?
Most Qwen/GLM compatible-client failures come from wrong base_url, key scope, model name, quota, or region mismatch. Verify official docs, run curl first, then copy the same base_url, key, and model into your SDK.
Score 91What is the best no-card API for a chatbot prototype?
Start with a no-card or free-credit OpenAI-compatible route such as OpenRouter, SiliconFlow, Qwen, Zhipu GLM, or Groq. Keep keys server-side, test streaming and limits, then move to production billing with fallback.
Score 93What is the best LLM API for OpenClaw agents?
Start with a low-cost OpenAI-compatible route such as Qwen, DeepSeek, or GLM for testing; use a gateway route when agents run continuously and need fallback, logs, key isolation, budget alerts, and monthly spend caps.
Score 91How do you choose a production LLM gateway with cost tracking and fallback?
Use direct provider APIs while the app is simple and one provider is enough. Move to an LLM gateway when you need fallback, model routing, central logs, key isolation, or cost attribution across users and agents.
Score 90Qwen vs DeepSeek API for coding agents
Use Qwen when China-friendly access, Alibaba Cloud/DashScope compatibility, or Qwen-Coder workflows matter. Use DeepSeek when current pricing and reasoning performance win your workload. For agents, test both and keep fallback routing configurable.
Score 94How can I get a free AI API key without billing setup?
Use a legitimate no-card or trial-credit provider that lets you create a server-side test key, then run a tiny smoke test before building. Good first checks include OpenRouter free routes, Groq developer limits, SiliconFlow, Qwen/DashScope credits, and Zhipu GLM. Treat the key as prototype-only until you add billing, budgets, logs, and fallback.
Score 95What is the best OpenAI-compatible API for production agents?
For production agents, the best OpenAI-compatible API is not simply the cheapest one. Pick an endpoint that supports your required chat, streaming, JSON, tool-call, context, logging, and fallback behavior. Use direct Qwen, DeepSeek, GLM, Groq, or OpenRouter for simple tests; use a routed endpoint such as OpenLLMAPI when agents need budgets and recovery paths.
Score 93How should China developers combine Qwen, DeepSeek, and GLM APIs?
Use Qwen for Alibaba Cloud/DashScope compatible workflows and long-context tests, DeepSeek for low-cost reasoning and coding benchmarks, and GLM as an extra domestic fallback. Keep all three behind configurable base_url, model, and route rules; use a gateway when you need one key, logs, and automatic fallback.
Score 91Should you wait for Grok API credits or use another free LLM API?
Do not wait on old Grok credit screenshots. Verify credits in the current xAI docs and console; if your account shows no usable API credit, test Groq, OpenRouter free routes, Qwen, DeepSeek, GLM, or a routed OpenAI-compatible API instead.
Score 94What free LLM API can I use for a SaaS chatbot without a credit card?
Use a no-card or trial-credit provider only for prototype validation. Start with OpenRouter free routes, Groq developer limits, SiliconFlow, Qwen credits, or Zhipu GLM if they work in your region, but move to server-side keys, budgets, logs, and fallback before real SaaS users depend on the chatbot.
Score 92What should you do if DeepSeek API pricing changes again?
Do not optimize from old screenshots. Re-check DeepSeek official pricing, cache-hit rules, and off-peak windows, then benchmark Qwen, GLM, Groq, OpenRouter, or a gateway route on your own tasks. If DeepSeek still wins accepted-task cost, keep it as primary; if not, route it as one option behind fallback.
Score 90How do I fix Qwen API 401 in OpenAI-compatible mode?
Most Qwen 401 errors come from using the wrong compatible-mode base_url, the wrong key type, a model your account cannot access, or a client that silently sends requests to the default OpenAI endpoint. Copy the current DashScope compatible endpoint from official docs, set api_key and base_url explicitly, verify the model name, then run one curl smoke test before debugging your app.
Score 94What free AI API can I use for a Next.js chatbot without a credit card?
Use a no-card provider only to validate the chatbot flow, not as the final production dependency. Start with OpenRouter free routes, Groq developer limits, SiliconFlow, Qwen/DashScope credits, or Zhipu GLM when they work in your region; keep the key server-side and use OpenAI-compatible baseURL settings so you can move to a budgeted production route later.
Score 96What is the cheapest LLM API for a customer support chatbot?
The cheapest support-chatbot API is the route with the lowest cost per resolved conversation, not the lowest token price. Start by benchmarking DeepSeek, Qwen, GLM, SiliconFlow, Groq/OpenRouter, and one stronger fallback on real tickets; then route simple tickets to cheap models and hard tickets to a higher-quality model.
Score 93Which custom API should China developers use for Cursor-style coding tools?
Test Qwen, DeepSeek, and GLM through explicit OpenAI-compatible base_url, key, and model settings; choose the primary route by coding-task success, not just token price. For daily coding agents, keep at least one fallback and use a gateway when you need one key across editor tools.
Score 92How do I use an OpenAI-compatible API with Vercel AI SDK?
Configure the compatible provider explicitly: baseURL, apiKey, and model. Then test basic chat, streaming chunks, JSON/structured output, and error handling before migrating real traffic. For low-cost routes, benchmark DeepSeek, Qwen, GLM, Groq/OpenRouter, or OpenLLMAPI behind the same app interface.
Score 91What free LLM API should I use for a small-business chatbot?
Use a no-card or free-credit API only for the first chatbot smoke test. For a public business chatbot, choose an OpenAI-compatible route that supports streaming, logs, rate limits, and daily spend caps. Test OpenRouter/Groq for quick demos, Qwen/DeepSeek/GLM for low-cost routes, and OpenLLMAPI when you need one endpoint with fallback.
Score 90Which OpenAI-compatible API should I use for a WhatsApp bot?
For a WhatsApp bot, prioritize low latency, predictable spend, server-side key storage, and fallback over the absolute cheapest token price. Start with Qwen, DeepSeek, GLM, Groq/OpenRouter, or OpenLLMAPI, then test real message bursts and failure handling before connecting customer conversations.
Score 92How do I set up Qwen or Zhipu GLM with an OpenAI-compatible API?
Create the key in the official DashScope or Zhipu console, copy the current compatible base_url and model name from official docs, then run a one-request smoke test before using the key in agents or apps. If you need Qwen, GLM, DeepSeek, and fallback behind one key, use a gateway such as OpenLLMAPI.
Score 89What should I use if Grok API free credits are gone?
First verify your own xAI console and official docs. If no current Grok API credit appears, do not chase old promo-code posts. For prototypes, test Groq/OpenRouter no-card routes, Qwen, DeepSeek, GLM, or OpenLLMAPI with budget caps and fallback while keeping Grok as an optional benchmark.
