# List call sessions

Lists your calls and file analyses, newest first. Filter with `call_id` to find the session of a provider call (Twilio `callSid`, Plivo `callUuid`, taken from the start message) or of your own call id. Page with `limit` and `cursor`. Requires scope `noesis:read`.

## Authentication

Send your API key as `Authorization: Bearer <your API key>`.

| `500` | Something went wrong on our side. |

Error bodies use the shape described in [Errors](https://platform.detectif.ai/docs/noesis/errors/), with a stable `error.code`.
