Quick verdict

Free API: Not confirmed in the current snapshot
Rate limits: N/A
Best model starting point: GPT-5.5
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

Production readiness checklist

Quota gate No confirmed free API quota is recorded; verify ChatGPT (OpenAI) docs before collecting keys.

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: 2026-05-21; official quota and pricing can change without notice.

cURL smoke test

Use this to verify endpoint, auth header, model name, response shape, and quota before adding SDK abstractions.

curl https://api.provider.example/v1/chat/completions \
  -H "Authorization: Bearer $CHATGPT_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "GPT-5.5",
    "messages": [{"role": "user", "content": "Hello from yangmao.ai"}]
  }'

Free API and pricing notes

API requires payment, no free tier. Codex (cloud coding agent) now available for enterprises.

Access and production risk

Relay or proxy may be needed

Requires proxy in China. Recommend API relay services or self-hosted Cloudflare Workers proxy.

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.
