# Get a peer registry

`GET /admin/peers/{peerId}`

## Request

- The document declares no server URL.
- Auth: none declared

**Experimental.** Gets the details of a single peer registry (by `peerId`).

This endpoint is only available when federation is enabled (`apicurio.federation.enabled`). Returns HTTP 409 (Conflict) otherwise.

This operation can fail for the following reasons:

* The `peerId` is invalid (HTTP error `400`)
* No peer registry with the `peerId` exists (HTTP error `404`)
* Federation is not enabled (HTTP error `409`)
* A server error occurred (HTTP error `500`)

## Response `200`

When successful, returns the details of a peer registry.

- Peer: A peer registry that this registry federates with.
  - `peerId` string, required: Unique id of the peer registry. Lowercase letters, digits, `.`, `_` and `-` only, at most 256 characters. `local` is reserved.
  - `url` string, required: Base URL of the peer registry, for example `https://registry.eu.example.com`.
  - `name` string: Display name of the peer registry.
  - `description` string: Description of the peer registry.
  - `enabled` boolean, required: Whether the peer registry is used for federation.
  - `credentialSecretRef` string: Name of the key in the registry's peer credentials directory that holds the credential for this peer. A reference only: the credential value is never stored or returned.
