# United States API

> Companies, prices, financial statements, SEC filings, filing items, news, and search for US public companies.

US endpoints live under `/us` and use SEC-native identifiers.

| Identifier | Example | Use |
| - | - | - |
| Ticker | `AAPL` | Convenient company lookup |
| CIK | `0000320193` | Stable SEC company identity |
| Accession number | `0000320193-25-000079` | Stable filing identity |

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.
