# 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.

![Example of get source](/files/iGLeP8fcjkS2AWeVueNp)

#### Simple usage example

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

```shell
curl --request GET \
  --url https://www.ebi.ac.uk/unichem/api/v1/sources/1
```

{% endtab %}

{% tab title="Python" %}

```python
import requests

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

payload = ""
response = requests.request("GET", url, data=payload)

print(response.text)
```

{% endtab %}
{% endtabs %}

Detail information on the response payload and usage [here](https://www.ebi.ac.uk/unichem/beta/api/docs#/Sources/get_unichem_beta_api_v1_sources_).&#x20;
