Models - HarnessRouter Docs | HarnessRouter

Endpoints

• GET /v1/models returns the global model catalog keyed by backend.
• GET /v1/harnesses/{id}/models returns the model set allowed for one configured agent.

Backend map

GET /v1/models is keyed by backend. The base harness claude-code corresponds to backend key claude; other base harnesses generally use the same key as the base name.

Both catalogs this page documents — GET /v1/models and the per-agent GET /v1/harnesses/{id}/models — are model discovery endpoints the Unified Harness Protocol assigns to its Harnesses chapter. See models in UHP's Harnesses chapter.
