# Call extension endpoint (GET)

`GET /api/v1/ext/{namespace}/{path}`

Proxy route for custom extension GET endpoints. The namespace uses reverse-domain notation (e.g. `com.example.diagnostics`). Available extensions and their self-describing tools are discoverable via `GET /api/v1/agent/capabilities`. This generic OpenAPI template represents a single path segment; clients should use each descriptor's concrete `path` value when an extension advertises a nested sub-path.

## Path parameters

- `namespace` string, required
- `path` string, required

## Response `200`

Extension-defined response.

- unknown

## Other responses

- `404` — Resource not found.
- `500` — Internal server error.
