Any OpenAI-compatible client¶

Claudin.io implements the OpenAI API surface, so any tool, SDK, or library that lets you set a custom base URL works. If your editor isn't listed in this section, use these generic settings.

The three values¶

Setting	Value
Base URL	`https://api.claudin.io/v1`
Model	`claudinio`
API key	your `sk-...` key

Most tools call the base URL field one of: Base URL, API Base, OpenAI Base URL, Endpoint, or Custom provider URL. Always include the /v1 suffix.

Environment variables¶

Many CLIs and SDKs read the standard OpenAI variables — set these and you're done. If you've exported your key, reuse $CLAUDINIO_API_KEY:

export OPENAI_BASE_URL=https://api.claudin.io/v1
export OPENAI_API_KEY=$CLAUDINIO_API_KEY

Supported endpoints¶

Claudin.io routes these OpenAI-style paths:

Endpoint	Purpose
`POST /v1/chat/completions`	Chat completions (the main one)
`POST /v1/completions`	Legacy text completions
`POST /v1/messages`	Anthropic Messages format
`POST /v1/responses`	Responses API (used by Codex)
`POST /v1/embeddings`	Embeddings
`GET /v1/models`	List available models

Authentication¶

Send your key as either:

Authorization: Bearer YOUR_API_KEY

or

x-api-key: YOUR_API_KEY

Both are accepted — pick whatever your client emits.
