# List project factory PR costs

`GET /experimental/projects/{projectId}/factory/metrics/cost/prs`

## Request

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

Lists the factory PRs behind the Cost per PR card (`GET .../factory/metrics/cost`) for the requested window (`filter[timestamp][gte]` to the exclusive `filter[timestamp][lt]`, at most 90 days, the last 7 days when neither is given), counted as the card counts them: one row per PR whose opening run, or any follow-up, is counted in the window. `firstRunCredits` and `followUpCredits` are the credits counted in the window, so the rows add up to the card’s `current.prCredits`, and the rows with `openedInWindow` number its `current.prsOpened`. `openedAt` is when the opening run was created, and `loop` and `skill` are the opening run’s project Loop (null when no Loop of the project started it) and its skill without its version. `runs` lists the PR's counted runs, oldest first, at most 20, and `runsTruncated` says there are more. `filter[opened]` keeps the PRs whose opening run is counted in the window (`inRange`, the rows with `openedInWindow`) or the rest (`earlier`), so an opening run still unfinished counts as `earlier`. `sort` is `-credits` (the default) or `-openedAt`, ties broken by URL; page links carry the resolved window.
