Using the Bioregistry to check for prefixes

[cthoyt]

The Bioregistry (https://bioregistry.io; https://github.com/bioregistry/bioregistry) integrates the resources mentioned on the readme as well as several more. You could ping its API to see if there is a prefix (or synonym of a prefix) already available:

import requests

prefix = ...
res = requests.get(f'https://bioregistry.io/api/registry/{prefix}').json()

I just realized it gives a 500 if there's no entry so I need to make an update. Alternatively you could pip install the package that holds the data and do

import bioregistry

resource = bioregistry.get('nope')
assert resource is None
