OpenAI Python API Setup

Use this page when you need a working Python starting point for OpenAI, then validate quota and model names in the official console before production.

Open official provider → Get one OpenAI-compatible key → Compare API gateway options →

Quick verdict

Free API: $5
Rate limits: 3 RPM (free tier)
Best model starting point: GPT-5.2
Mainland China access: proxy/relay likely needed

Provider fit matrix

Best fit Image generation prototypes, creative automation, and media workflows

Watch out Image/video credits can burn faster than chat tokens; test with small batches first

Production fallback Keep at least one compatible backup provider before shipping

OpenAI API buyer intent notes

Who should care

Best for teams that need frontier OpenAI models, ChatGPT ecosystem compatibility, and official platform features, but can handle billing and regional access friction.

Decision trigger

Use OpenAI directly when model quality and official API support beat free/no-card constraints; otherwise compare compatible fallback routes first.

Watch out: Free-credit claims change often. Confirm billing, API key access, model availability, and China reachability in the platform before production work.

Production readiness checklist

Quota gate Start inside $5; log usage before adding retries or batch jobs.

No-card check Try the free path first, then confirm whether billing is required for API keys, higher RPM, or production endpoints.

Regional smoke test Run signup, dashboard, DNS, TLS, and first API call checks from mainland China before launch.

Source freshness Snapshot date: 2026-06-16; official quota and pricing can change without notice.

Python setup snapshot

Start with the smallest possible chat completion, then move the key to your server-side secret manager before production.

from openai import OpenAI

client = OpenAI(
    api_key="your-openai-key",
    # Check OpenAI docs for its OpenAI-compatible base URL
)

response = client.chat.completions.create(
    model="GPT-5.2",
    messages=[{"role": "user", "content": "Hello from yangmao.ai"}],
)
print(response.choices[0].message.content)

Free API and pricing notes

$5 free credits for new accounts, valid for 3 months, pay-as-you-go after

Access and production risk

Relay or proxy may be needed

Requires VPN, not directly accessible from China

How to set it up

Create or locate your provider API key in the official dashboard.

Install the OpenAI-compatible Python SDK or the provider-supported SDK.

Set the API key in an environment variable instead of hard-coding secrets.

Run a small OpenAI chat completion with GPT-5.2.

Watch free credits, RPM/TPM limits, response shape, and error messages before scaling.

OpenAI production validation table

Use this table before sending real users, scheduled agents, or paid traffic to OpenAI. The goal is to validate source freshness, quota behavior, regional access, and fallback needs instead of trusting a stale free-credit claim.

Check Pass condition If it fails

Signup and billing state Key creation works and the account can spend the recorded $5. Compare OpenAI alternatives or route through a gateway before inviting users.

First request from target region Proxy, relay, or non-mainland deployment path is documented before launch. Do not ship cron jobs or public demos until latency, DNS, TLS, and auth are repeatable.

Quota, retry, and error shape Rate-limit behavior matches the current 3 RPM (free tier) note or official dashboard values. Cap retries, add request logging, and keep a second route for 429/5xx bursts.

Cost per accepted task Real prompts stay within your target token, query, image-credit, or compute budget. Use cheaper primary routes, caching, shorter prompts, or fallback only after validation failure.

FAQ

Does OpenAI have a free API?

Yes. Current yangmao.ai record: $5. Rate limit note: 3 RPM (free tier).

Is OpenAI OpenAI-compatible?

The recorded setup uses an OpenAI-compatible pattern or SDK-style call. Validate the latest base URL and model names in OpenAI docs.

Can I use OpenAI from mainland China?

OpenAI may need a proxy or relay from mainland China. Test latency and signup before production.

What should I do when OpenAI credits run out?

Compare the alternatives below, check /en/free-ai-api/, and shortlist official providers or API gateway options before production.

Should I start with OpenAI or a free API alternative?

Start with OpenAI when official model quality is the priority. Start with Qwen, Gemini, Groq, OpenRouter, or a relay when no-card testing, lower cost, or mainland China access matters more.
