# Mixen API

> OpenAI-, Anthropic- and Gemini-compatible API to 100+ models — text, images, video, music, speech, embeddings and files — paid in roubles from one balance. Docs are bilingual: Russian at /docs/ (the sets below), English at /docs/en/ (the EN sets under Optional).

- OpenAI-compatible base URL: `https://api.mixen.ai/v1` (Chat Completions, Responses, images, audio, video, embeddings, files). Auth: `Authorization: Bearer mxn-...`.
- Anthropic-compatible base URL: `https://api.mixen.ai` (the SDK and Claude Code append `/v1/messages` themselves — do not add `/v1`).
- Gemini-compatible base URL: `https://api.mixen.ai/v1beta`. MCP server: `https://api.mixen.ai/v1/mcp`.
- Model ids come from `GET https://api.mixen.ai/v1/models` (public, with prices in RUB and USD); vendor prefix is optional (`openai/gpt-5.6-sol` or `gpt-5.6-sol`).
- Every docs page is also available as raw Markdown at `https://api.mixen.ai/docs/<slug>.md` (e.g. `/docs/quickstart.md`, `/docs/en/connect.md`) — same slugs as the HTML pages.
