# Data-source licensing & attribution catalogue

`GET /data-sources`

Returns the licensing and attribution catalogue for every data source.
Public — no API key required.

Use this to render the credits your application must display. Sources
under open licenses that require attribution (CC-BY, OGL v3.0, ODbL,
NLOD, Licence Ouverte, DL-DE→BY) carry the exact credit string in
`attribution`. List responses (`/events`, `/features`) also embed an
inline `attribution[]` for the sources present in that response.

## Response `200`

The data-source catalogue

- object
  - `data` SourceCredit[]
    - `attribution` string — The exact credit string this source's license requires you to display.
    - `license` string
    - `license_url` string, uri
    - `source_code` string — Jurisdiction or program code (e.g. `ESP`, `OSM`, `EIA`).
    - `source_name` string
