Mixen API

Quickstart

Key, base URL and a working call in five minutes.

Models and pricing

170+ models across every modality, and what they cost.

API Reference

27 /v1 endpoints with parameters and responses, Responses and Anthropic Messages included; Gemini and MCP live in the guides.

Connect your tool

Claude Code, Codex, Cursor, Cline, OpenCode, SDKs and no-code — a tile per client, the base URL for its protocol, a two-minute guide. Plus an MCP server for agents.

What it does

Text

Chat with streaming, tool calling, structured JSON output, image and PDF input, tunable reasoning effort, web search.

Images

Generation, reference-based editing and upscaling: aspect ratios, resolutions up to 4K.

Video and music

Async jobs: create, poll, download. Image-to-video and video upscaling included.

Speech and vectors

Synthesis, transcription and embeddings through the familiar OpenAI endpoints.

Files and artifacts

File storage with a quota, generation history with artifact download, balance and transaction log — all programmatic.

Why it is drop-in

Requests and responses match OpenAI, error envelope included. Any compatible SDK, and any client that lets you set a custom base_url, works unchanged. Need the Anthropic protocol — there is /v1/messages; an agent on GoogleGenAI — /v1beta. MCP agents get a single URL and key.

Schema and sandbox

• openapi.json — the machine-readable schema: feed it to an SDK generator, to Postman, or to your own agent.
• Interactive reference — Scalar with a “send request” form; Swagger UI and ReDoc render the same data.

The schema is dumped from the code when the docs are built, so it cannot run ahead of or lag behind what is deployed.
