Aggregate dataset coverage snapshot

Aggregate snapshot of the served dataset.

Pure aggregate counts (entities/filings/sources/ countries + fiscal-year range): no per-entity provenance, no mapping.

API error details.

API response metadata.

Pagination fields (page / per_page / total) are populated on collection endpoints only. They are omitted from the payload on single-resource endpoints.

HATEOAS-style pagination cursors.

Host-relative path + query links for a collection page. Present on collection endpoints, null fields where a page doesn't exist (next on the last page, prev on the first). The whole links object is omitted from single-resource responses (see ApiResponse serializer).
