Detail for one error signature
Drill-down for a single error signature, keyed by fingerprint.
Returns summary stats, a time series, top-N breakdowns across the requested dimensions, and recent sample beacons, all in one request.
bearerAuthAuthentifizierungBearer <fm_… / fmo_…>API token generated from the fastmon dashboard (Account → API Token) or at organization level (fmo_…, one that outlives its creator). Send as Authorization: Bearer fm_... or paste the full token (including its prefix) into the Authorize dialog.

Request for drill-down on a single error signature.
Identified by fingerprint (server-computed canonical key), not the
legacy 4-tuple. Backfillable: if the fingerprint rule changes, an
UPDATE rewrites every row deterministically; old request URLs become
invalid by design rather than silently matching the wrong bucket.

A width under an hour allows at most 1500 buckets.
"auto""auto""minute""five_minutes""fifteen_minutes""hour""six_hours""day"timezone?|IANA time zone whose boundaries start the six_hours, day, week and month buckets, such as Europe/Berlin. A day is 23 or 25 hours long across a DST switch. Bucket timestamps stay UTC. In a zone whose offset is not whole hours a bucket starts at the UTC hour that holds the local boundary. Without it the buckets start at UTC boundaries

request*The request as the server resolved it
status?ErrorSignatureStatusacknowledged while an error_acknowledgement of the organization holds the row's fault key, or its fingerprint where it has no key. Derived, never stored on the row. An acknowledged signature still counts in every total.
"open""open""acknowledged"acknowledged_at?Acknowledged AtWhen a person acknowledged the signature. Absent while open.
date-timenote?NoteThe free text left on the acknowledgement. Absent without one.
acknowledgement_id?Acknowledgement IdThe acknowledgement the row matches, the address of /error-acknowledgements/{acknowledgement_id}. Absent while open.
uuidsummary*Aggregate summary for the selected error.
error_type?Error TypeThe group's error type, repeated here so the detail reads alone.
""message_kind?Message KindThe group's message shape (selector_invalid, not_defined, ...), collected in every mode. '' when the message is one the customer wrote themselves. The field a diagnosis should be built on.
""message_value?Message ValueThe identifier that shape names, '' when it names none.
""sample_message?Sample MessageOne example message of the group, PII-stripped. Empty when the site does not collect messages, which is the default.
""messages_collected?Messages CollectedEvery application in scope stores error messages, so an empty sample_message means the error carried none. False means the message may simply not be collected.
