Yir is an asynchronous-first AI gateway for long-running generation tasks. It gives your application a stable task ID, explicit status polling, and a consistent billing record while Yir manages certified provider routes. The current developer preview is intentionally narrow: GPT Image 2 text-to-image through the certified KIE-compatible and APIMart-compatible routes. It is not the complete Yir v1 release. Video, music, 3D, arbitrary provider paths, and a general-purpose low-latency LLM proxy are not part of this preview contract.

​
Start here

  1. Create and protect a Yir API key.
  2. Submit and query your first task.
  3. Follow the production integration guide.
  4. Learn the task lifecycle and billing model.

​
Two source-compatible surfaces

Choose the request and response shape your integration already understands:
  • KIE-compatible — submit with POST /kie/api/v1/jobs/createTask, then query with GET /kie/api/v1/jobs/recordInfo.
  • APIMart-compatible — submit with POST /apimart/v1/images/generations, then query with GET /apimart/v1/tasks/{id}.
Both surfaces use the same host and the same Yir API key:
Yir does not accept an upstream provider credential from your request. Provider credentials are managed inside Yir and never belong in client code, request bodies, or query parameters.
