# Register Server Jwk

`PUT /server-credentials/{client_id}/key`

Register or update a server's RSA public JWK.

Only the server identified by `client_id` may register its own key. The
server presents its platform JWT (from Origin via client_credentials).
`client_id` in the path must match `client_id` in the token so servers
cannot register keys on behalf of other servers.

## Path parameters

- `client_id` string, required

## Request body

- RegisterJwkRequest
  - `public_jwk` object, required

## Response `204`

Successful Response

## Other responses

- `422` — Validation Error
