| **Address**   | `https://api.hanzo.ai/v1/o11y/query_range` |
| **Method**    | `GET`                                      |
| **Operation** | `get_o11y_query_range`                     |
| **Auth**      | `Authorization: Bearer $HANZO_API_KEY`     |

Runs a Prometheus-style range query over metrics — the
legacy read that predates the v5 querier — and returns the matrix, vector or
scalar the query resolved to.

Callers need the viewer role; the runtime's own gate enforces it.

## Request

6 fields.

| Field     | In    | Type   | Required | Description                                                                                         |
| --------- | ----- | ------ | -------- | --------------------------------------------------------------------------------------------------- |
| `start`   | query | string | yes      | Start is the window start — a unix timestamp (seconds, with optional fraction) or an RFC 3339 time. |
| `end`     | query | string | yes      | End is the window end, in the same form as Start, and not before it.                                |
| `step`    | query | string | yes      | Step is the query resolution, e.g. 60s, 1m, 1h — a positive duration.                               |
| `query`   | query | string | yes      | Query is the PromQL expression to evaluate.                                                         |
| `stats`   | query | string | —        | Stats, when "all", asks for query statistics alongside the result.                                  |
| `timeout` | query | string | —        | Timeout caps how long the query may run, e.g. 30s, 1m — a positive duration.                        |

## Response

| Status    | Body                          | Meaning           |
| --------- | ----------------------------- | ----------------- |
| `200`     | o11y.O11yMetricsQueryRangeOut | ok                |
| `202`     | Approval                      | held for approval |
| `default` | problem-details               | refused           |

`200` body — 2 fields.

| Field    | In   | Type   | Always | Description                                                                  |
| -------- | ---- | ------ | ------ | ---------------------------------------------------------------------------- |
| `data`   | body | any    | —      | Data is the result — its result type, the value, and query stats when asked. |
| `status` | body | string | —      | Status is "success".                                                         |

Failure carries the platform error shape — see [Errors](https://docs.hanzo.ai/docs/errors).
