MetisRouter API Docs

Copy production-ready API examples for text, responses, image, video, audio, embeddings, and developer tools.

Use MetisRouter with OpenAI-compatible chat, Responses-style requests, Anthropic Direct, Gemini Direct, image, video, audio, embeddings, and agent workflows. Copy exact model IDs from the model catalog before sending production traffic.

API base URL

Use https://api.metisrouter.com/v1 as the API base URL and send your MetisRouter API key in the Authorization header. For OpenAI-compatible text requests, call POST /v1/chat/completions; use Responses, image, video, audio, embedding, Anthropic, or Gemini endpoints only when the selected model lists that endpoint family.

Model IDs

Browse Models or Model IDs for the published API model IDs available on the platform. Display names can be prettified, so production requests should copy exact API model IDs and the endpoint family shown in the catalog.

Production calling path

Confirm the model ID, endpoint, output limit, and pricing unit before sending a short request. Do not force image, video, audio, embedding, or direct-provider models through an incompatible chat endpoint.

Verification path

After the first request, use Usage Logs to confirm request id, model id, endpoint, latency, token or asset usage, and charged USD. That record is the primary evidence for debugging and billing review.

Conversion and support path

Before increasing traffic, use the cost calculators to estimate request reserve and monthly workflow cost; send production issues with request IDs to support@metisrouter.com and high-volume planning to hello@metisrouter.com.
