# Look up a caller

Two routes answer "who is this?". One is rich, one is lean.

| Route | Answers with | Use it for |
| --- | --- | --- |
| `GET /v1/callers/{number}` | Contacts (up to 5), recent calls with who handled them and the AI summary, texts and WhatsApp messages, and the last call each way | An AI agent or a screen that needs context before hello |
| `GET /v1/contacts/lookup?phone=` | The contact records for the number, up to 10 | Matching a caller to a record in your CRM |

- Any formatting works in the number, and a leading 1 is dropped. It needs at least 7 digits.
- `days` looks back 1 to 365 days, 90 by default. `limit` caps the calls, and the messages, at 1 to 50, 10 by default.
- `last_call`, `last_incoming` and `last_outgoing` repeat an entry from `calls`, or are `null`.
- Transcripts stay out unless you add `include=transcripts`. Every read is written to your HIPAA access log.
