# Get Block Query Engine Credentials

`GET /api/v1/block/credentials`

Per-client Polaris credentials for the "Connect Your Query Engine" modal.

Lazy-mints when the client has no Polaris credentials yet — the SQL
editor calls this on load, before a Block request has ever run the
provisioning step. Eligibility (Enterprise plan + Block role) is
already enforced above, so a missing-creds call here is a legitimate
first-time mint, not a leaked admin path.

## Response `200`

Successful Response

- BlockQueryEngineCredentials — Per-client Polaris (Iceberg REST catalog) connection details for the "Connect Your Query Engine" modal. ``client_secret`` is the raw plaintext secret — sensitive, only returned to the client's own users over HTTPS.
  - `client_id` string, required
  - `client_secret` string, required
  - `catalog_uri` string, required
  - `warehouse` string, required
