Overview
Welcome to the Concurred API documentation
What is Concurred?
Concurred provides a single API to access 9 top AI models plus media generation (speech, music, video). Think of it as a universal AI gateway — one API key, any model.

Available endpoints
Pick the one that matches what you're building.
| Endpoint | What it does |
|---|---|
/api/v1/chat/completions | Chat with one AI model. Works with the OpenAI SDK — change two lines and your existing code runs on Concurred. |
/api/v1/battle | Two models answer the same question side-by-side so you can compare them. |
/api/v1/fight | Up to 8 models answer, see each other's answers, and vote on the best one. |
/api/v1/search | Web search (powered by Exa). Returns a plain list of results — no AI involved. |
/api/v1/themes | 1000+ ready-to-inject design-system themes for AI-generated UI (powered by October). |
/api/v1/image | Generate or edit images. |
/api/v1/video | Generate videos. |
/api/v1/media | Text-to-speech and AI music. |
/api/v1/fashion | Virtual try-on and fashion image AI. |
If you're already using /api/chat, it still works — see the Chat API (Legacy) page for the mode mapping. New projects should use the endpoints above.
