*Monitor metric timeseries*

| Parameter | Required | Description |
| --- | --- | --- |
| `id` | yes | Monitor id — e.g. `mon_0f2c8b1d4e6a7c9b0d1e2f3a` |
| `metric` | yes | Metric key to chart; a 422 lists the metrics this monitor has recorded — e.g. `content_length` |
| `from` | no | Only points at or after this ISO-8601 time — e.g. `2026-01-01T00:00:00Z` |
| `to` | no | Only points at or before this ISO-8601 time — e.g. `2026-02-01T00:00:00Z` |
| `dry_run` | no | Read a zero-credit estimate without fetching sources, running AI, or reserving credits. Cache status is a snapshot, not a guarantee at execution. Accepted values: 1, 0, true, false. Case, spaces, hyphens and underscores are interchangeable. — e.g. `1` |

### Useful optional inputs

- `dry_run`: Read a free estimate before fetching sources or scheduling paid work. Zero credits; cache status and availability are snapshots rather than guarantees.

**Cost:** free — 0 credits.
