List error groups

List error signatures. Failures grouped by error signature in a period, most frequent first. Every count covers the period; firstSeen is the first occurrence still stored, not bounded by it. Moderate: one aggregate query.

GET/api/v1/projects/{projectId}/errors

Parameters

Parameter	Description
`projectId`string · pathrequired	A project id from GET /projects.
`days`7 \| 30 \| 90 · default 30	The period, in days, ending now. Must not exceed the plan’s retention (Standard 60, Pro 90 days); a longer period is refused with 400 invalid_period rather than answered with less data.
`page`integer · default 1	1-based page number. A page past the end answers the last page.
`perPage`10 \| 25 \| 50 · default 10	Rows per page.
