List span groups
Group spans by a supported dimension and return one aggregate row per group. trace and thread roll spans up through their dedicated entity views.
Authentication
AuthorizationBearer
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.
OR
AuthorizationBearer
Use a dashboard JWT only for dashboard-authenticated endpoints. Respan API-key endpoints use the respanApiKey auth field instead.
