# The source roster, by class

`GET /api/sources`

## Request

- Base URL: `https://api.signalbureau.ai`
- URL: `https://api.signalbureau.ai/api/sources`
- Auth: none declared

The roster the /sources/ page shows, as data: each source class with its sources' names and publisher homepages, plus the domains and regions we cover. `asOf` is the date the roster last changed, not the time of the request. Names and homepages only: feed addresses, per-feed volume and per-source grading are not published (the `policy` field says so). Feed health by lane is served to identified callers at /api/source-health. Free, no key.

## Response `200`

The roster (schema `sb.sources.v1`).
