Returns

Every response uses the same envelope, {data, meta, links}. The data field carries the answer (an object for a single snapshot, a list when there is one row per entity). The meta field carries the trust contract: the reference periods, retrieved_at, the per-source attribution you reproduce on publish, and the stale flag. The links field offers a csv alternative when one is available.

Draws from

This signal joins data from one source. Each source page lists the underlying datasets and canonical series.

Cross-source signals join multiple sources into one response. Reliability: a signal returns current data or a clear 503; it never serves an older vintage as the current answer.
