## monitors/trends

`GET /v1/monitors/trends`

A metric over time with the previous period and the baseline beside it, so a change can be judged against what is normal for this monitor.

*Monitor trends*

| Parameter | Required | Description |
| --- | --- | --- |
| `id` | yes | Monitor id — e.g. `mon_…` |
| `metric` | no | findings, or any numeric metric the runs record — e.g. `findings` |
| `days` | no | Window, up to 90 days — e.g. `30` |
| `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.
