### Search Proteins by UniProt Accession (Python)

Source: https://www.ebi.ac.uk/proteins/api/doc/exampleScripts.html

Use this script to retrieve UniProtKB information for a specific accession. The request accepts XML format.

```python
import requests, sys

    requestURL = "https://www.ebi.ac.uk/proteins/api/proteins?offset=0&size=100&accession=P21802"

    r = requests.get(requestURL, headers={ "Accept" : "application/xml"})

    if not r.ok:
        r.raise_for_status()
        sys.exit()

    responseBody = r.text
    print(responseBody)
```

### Retrieve All Coordinates by Gene Name (curl)

Source: https://www.ebi.ac.uk/proteins/api/doc/exampleScripts.html

This command retrieves all genomic coordinates for a gene name by setting the page size to -1, which streams all results. The offset parameter is ignored in this mode.

```bash
curl -X GET --header 'Accept:application/json' 'https://www.ebi.ac.uk/proteins/api/coordinates?size=-1&gene=FGFR2'
```

### Search Coordinates by Gene Name (Python)

Source: https://www.ebi.ac.uk/proteins/api/doc/exampleScripts.html

This script fetches genomic coordinates for a given gene name. It defaults to returning JSON format. Optionally, filter by taxid for human-specific results.

```python
import requests, sys

    requestURL = "https://www.ebi.ac.uk/proteins/api/coordinates?offset=0&size=100&gene=FGFR2"

    r = requests.get(requestURL, headers={ "Accept" : "application/json"})

    if not r.ok:
        r.raise_for_status()
        sys.exit()

    responseBody = r.text
    print(responseBody)
```
