FBI API (Danish Public Libraries / DBC)

About

DBC (Danmarks Biblioteker Center) operates FBI API, a GraphQL API covering bibliographic search, work/manifestation metadata, library holdings, and availability across the Danish public library system. This replaced the older "DBC Open Platform" (openplatform.dbc.dk), which was retired at the end of 2024 and now returns HTTP 410 Gone — any integration still pointed at the old platform is broken. FBI API honors the same OAuth2 access tokens.

Agent Use Cases

• 01Search Danish public-library holdings and availability from an agent
• 02Build a reading-recommendation tool against DBC's bibliographic metadata

Notes

GraphQL, not REST. OAuth2 bearer-token auth — historically a library had to sponsor a client_id for third-party access; the exact current self-serve registration flow for independent developers was not fully confirmed, so don't assume open signup without checking. IMPORTANT: openplatform.dbc.dk is dead (410 Gone) — use fbi-api.dbc.dk for any new integration.
