}'Free API and pricing notes
未确认当前长期免费额度；以 xAI Console 为准
Search demand for Grok free credits is high, but many $150 credit or promo-code posts are stale. For production, trust only docs.x.ai and the xAI Console billing page.
Access and production risk
Relay or proxy may be needed
Mainland China access, signup, and billing reliability should be validated case by case; prepare Qwen, DeepSeek, GLM, or a compliant API-gateway fallback for China-facing products.
How to set it up
Create an API key and copy the provider endpoint from official docs.
Export the key into your shell session.
Send a minimal chat completion payload with cURL.
Check status code, JSON body, and rate-limit headers.
Move the tested endpoint into your app or fallback relay.
xAI Grok API production validation table
Use this table before sending real users, scheduled agents, or paid traffic to xAI Grok API. The goal is to validate source freshness, quota behavior, regional access, and fallback needs instead of trusting a stale free-credit claim.
