/us and use SEC-native identifiers.
Use company endpoints for identity, financial endpoints for normalized or as-reported statements, and filing endpoints for EDGAR metadata and content. Filing search returns evidence tied to an accession and source location.
/us/news is a separate, publisher-syndicated signal layer over US business, regulator, and macro feeds. It is keyed on the publisher’s own link and timestamp rather than on a CIK or accession, so treat it as a discovery and event surface, not as a filing record. It returns headline, link, publish time, category, and the publisher’s summary — never full article text.
