Lists failed spans grouped by fingerprint, most failures first, with each group's reach and triage state. Counts come from a rollup refreshed every 10 minutes, so the range is widened to whole hours.

Authentication

Use your Respan API key for Respan API authentication. Enter only the Respan API key value; clients send Authorization: Bearer <RESPAN_API_KEY>. For /api/responses, provider credentials such as Perplexity, OpenAI, or Azure OpenAI go in Settings -> Providers or respan_params.credential_override in the request body, not in this authentication field.
