The Errors report: distinct JavaScript error messages ranked by occurrence, a single error’s detail, its chart, and its individual occurrences. Rows in the Events log carry an error_id — the same fingerprint id used here — so an error event links straight into this report. An error is addressed by {error}, its deterministic fingerprint (a UUID derived from the site and the exact error message; the id field returned by the endpoints below). Fingerprint resolution is range-independent — a known fingerprint always resolves, even for a range with zero matching occurrences — but a fingerprint that has never belonged to the site returns 404 Not Found, so one team can never probe another’s errors. A site is addressed by {siteKey} (UUID or domain). All endpoints require Authorization: Bearer {token} and accept the shared range/from/to and filter query parameters described in Conventions.

List error names

Distinct error messages ranked by occurrence count over the resolved range, with session counts. Scroll-paginated with the standard data/meta/links envelope — see Conventions. Query parameters Filter dimensions are also accepted. Response — each item in data: Status: 200 OK.

Get an error

A single error group’s summary over the resolved range/filters. Path parameters Query parameters Filter dimensions are also accepted. A recognized fingerprint outside the requested range/filters still returns 200 OK with occurrences/sessions at 0, not 404 — only an unknown fingerprint 404s. Response — flat object: Status: 200 OK (404 for an unknown fingerprint).

Error timeseries

Per-bucket occurrence counts for one error — the “Errors over time” chart on the error’s detail page. Path parameters Query parameters Filter dimensions are also accepted. Response — flat object: Status: 200 OK (404 for an unknown fingerprint).

List error events

Individual occurrences of one error, newest first, with the full stack detail. Scroll-paginated with the standard data/meta/links envelope. Path parameters Query parameters Filter dimensions are also accepted. Response — each item in data: Status: 200 OK (404 for an unknown fingerprint).
