Overview

Institutional ("site-license") access check by IP address. Given the requester's IP, this returns the membership-type subscriptions on the site whose authorized IP ranges include it — access granted to a whole IP range rather than to a named member. This is how an institution (library, campus, office) unlocks content for any visitor on its network.

Example:

curl --request GET \
  --url 'https://www.pelcro.com/api/v1/sdk/members/ip/authorization?site_id=1025'

Notes

• Public — no authentication required.
• The requester's IP is detected automatically; site_id is required.
• Returns 404 No subscriptions found when no membership grants access to the IP.
