# Test Stored Provider

`POST /v1/provider-credentials/{instance}/test`

Verify a stored provider's key by listing its models, without exposing the key.

## Path parameters

- `instance` string, required

## Response `200`

Successful Response

- TestProviderResponse — Result of a live provider connection test.
  - `discovery_unsupported` boolean — True when the test failed only because this backend serves no model-listing endpoint, so the credentials could not be verified this way but may still work for requests.
  - `error` string, nullable
  - `model_count` integer, required
  - `ok` boolean, required

## Other responses

- `422` — Validation Error
