Crossref
Let AI connect your sources for you
Skip the manual setup — run this in your project and the wizard auto-detects your databases and APIs and connects them to PostHog.
Connect Crossref to PostHog to sync your data into the PostHog data warehouse for analysis and modeling.
Crossref's API is free and public — no API key needed. Add a contact email to get routed to Crossref's faster "polite pool".
The Works table covers Crossref's full DOI registry (160 million+ records), so set a member ID, funder ID, or journal ISSN below to scope which works sync. The Members, Funders, Types, and Licenses tables always sync in full.
