Response

No fixed example. This service returns live data from an upstream source. A stored example would be a snapshot presented as a current figure, so none is published.

Every response is wrapped in the same envelope: data plus warnings, sources, confidence, informational_only and a measured processing_ms. See the envelope reference.
