# Get project factory failure rates

`GET /experimental/projects/{projectId}/factory/metrics/failure-rates`

## Request

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

Counts the finished runs of the project's Loops created 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, and how many of them failed, by cause. `series` has one point per UTC day that the current window touches, with its finished and failed runs and zeros included, so the points add up to `current`.

## Path parameters

- `projectId` string, uuid, required

## Query parameters

- `filter[timestamp][gte]` string, date-time
- `filter[timestamp][lt]` string, date-time

## Headers

- `Authorization` string

## Response `200`
