# Sources

Every source the Assyro API serves (14), with its publisher and licence: FDA databases, clinical trials, labels, EU and UK law and guidance, and more.

Source: https://www.assyro.com/docs/sources

`GET https://api.assyro.com/v1/sources`

> **Note:** Preview: `api.assyro.com` is not serving production data yet. This page follows the API's published description and may change before launch.

Each source is searched and read the same way: `GET /v1/sources/{id}/search` with the source's own parameters, and `GET /v1/sources/{id}/records/{recordId}` for one record. Every record carries its source link; sources whose licence asks for attribution carry it on every record.
