# Get project factory utilization

`GET /experimental/projects/{projectId}/factory/metrics/utilization`

## Request

- Base URL: `https://api.tessl.io`
- URL: `https://api.tessl.io/experimental/projects/{projectId}/factory/metrics/utilization`
- Auth: none declared

Counts the PRs opened in the project's repository, from GitHub webhooks, in the requested window (`filter[timestamp][gte]` to the exclusive `filter[timestamp][lt]`, at most 90 days, the last 7 days when neither is given) and in the window of the same length just before it, by open time. `factoryPrs` counts those a launch run produced. Counts cover the whole repository, whatever the project’s subpath. `trackedSince` is when the repository’s record starts, null before its first PR; earlier PRs are not counted. `series` has one point per UTC day that the current window touches, zeros included, and its points add up to `current`.
