# United States API

> Companies, prices, financial statements, SEC filings, filing items, 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.
