# List Model Metadata

`GET /v1/models/metadata`

Per-model metadata for the dashboard's detail view, from models.dev.

Covers every model models.dev lists under a configured provider, keyed by the
``instance:model`` selector the dashboard uses. ``available`` is false when
enrichment is disabled (``models_dev_metadata``) or models.dev could not be
reached; the response is then empty and the UI falls back to bundled data.
Master-key gated: it describes the gateway's configured providers.

Answers from the cached catalog, kept warm by a background refresher, so the
dashboard never waits on the models.dev fetch timeout.

## Response `200`

Successful Response

- ModelMetadataResponse — models.dev metadata keyed by ``provider:model``.
  - `available` boolean, required — False when metadata could not be loaded (enrichment disabled or models.dev unreachable).
  - `models` object
  - `source` string
