## Common Questions

Do I need a Crossref account or API key?

No. You need only your Anysite key — Anysite talks to Crossref on your behalf, so there’s no separate registration and no second key to manage across the 12 endpoints.

How many works are covered?

The index spans over 183.7 million DOI-registered works from 25,000+ member organizations — journal articles, books, book chapters, conference papers, datasets, reports, and preprints across every discipline. The type filter on works search restricts results to one kind.

Can I trace which works a funder supported?

Yes. Look the funder up in the Crossref Funder Registry by name or id, then call /api/crossref/funders/works to list everything it funded — with grant and award details attached to each work.
