Retrieve a JWT-compliant access token for use with all other endpoints.

📘

All tokens currently expire after 24 hours (86,400 seconds), but we suggest refreshing tokens every 12 hours (43,200 seconds).

Here's an example of using the returned token in an API call:

curl \
  --url "https://api.ocrolus.com/v1/books" \
  --oauth2-bearer "eyJhbGciOiJ...2hUye_4CpIvQ"

See our guide on using API credentials for more details.
