Por ejemplo, aquí está usando el primer tag (probablemente tendrás solo un tag) y el nombre de la *path operation* (el nombre de la función).

Puedes entonces pasar esa función personalizada a **FastAPI** como el parámetro `generate_unique_id_function`:

/// tip

When raising an `HTTPException`, you can pass any value that can be converted to JSON as the parameter `detail`, not only `str`.

You could pass a `dict`, a `list`, etc.

They are handled automatically by **FastAPI** and converted to JSON.

### Per-bucket Metrics

Metrics with a `/bucket` component in the path return results for each specified bucket in the deployment. These endpoints **require** providing a list of buckets as a `bucket` query parameter.  The endpoint then returns only metrics for the given buckets, with the bucket name in a `bucket` label.
