# Observability

Observability spans are records of agent runs that capture timing, model usage, token consumption, and error details for every run. Use these endpoints to query spans across runs or retrieve the full detail of a specific span by ID.

For SDK walkthroughs, see [Observability](/flow/sdk/observability).
