API reference essentials
Authentication
Every request needs an Authorization header with your API key as a Bearer token. Keys are created in the console under API Keys and start with your account prefix. Keep keys server-side; never ship them in client-side code.
Authorization: Bearer $CLAUDEN_API_KEY
Streaming
Both endpoints support server-sent events. Set "stream": true in the request body and read the response line by line; chunks follow the OpenAI delta format on /v1/chat/completions and the Anthropic event format on /v1/anthropic. Remember to handle the final [DONE] line and network timeouts.
Model naming
The model parameter routes your request: claude-* names go to Anthropic, gpt-* to OpenAI, gemini-* to Google. The exact list of enabled model names and per-token prices is always on the pricing page — use those strings verbatim.
Error codes
| HTTP | 类型 |
|---|---|
401 | Invalid or missing API key. Check the Authorization header. |
402 | Insufficient balance. Top up to continue; requests resume immediately after credit. |
404 | Unknown model name or wrong endpoint path. |
429 | Rate limited. Slow down or retry with exponential backoff. |
500+ | Upstream or gateway error. Safe to retry once with backoff; contact support if it persists. |
