# Sources

Detail information from the sources, where our compound references are pointing to, can be access programatically through our web services:

* Single source: `https://www.ebi.ac.uk/unichem/api/v1/sources/{source_id}`
* All sources: `https://www.ebi.ac.uk/unichem/api/v1/sources/`

### Single Source

Every source is assigned a unique numeric identifier in our database, with this ID a single source details can be fetch.

A <mark style="color:blue;">**GET**</mark> call to /sources/{source\_id} where {source\_id} is the unique identifier for that source.

{% tabs %}
{% tab title="Curl" %}

```shell

  --url https://www.ebi.ac.uk/unichem/api/v1/sources/1
