Common questions on API usage, quota, sourcing and error diagnosis.
Q: Can one key be shared?
A: It can, but sharing a single key across systems is not recommended. Separate keys per service or environment make usage traceable and let you revoke one without affecting the rest.
Q: What should happen on a 429?
A: Back off and retry, and reduce short-term concurrency. If you sit near the ceiling persistently, the query strategy or the plan needs to change.
Q: How do I tell how current the data is, and where it came from?
A: Read the freshness, source_role and lineage fields. Where a row came from a helper or fallback source, the response keeps that role marked.
Q: A field will not parse — what should I check first?
A: Confirm the dataset and the type of the data, then the period/date field, the field's own type, and the source metadata.
