FAQ from Citation & Source Verification

What tools does Citation & Source Verification expose?

Three tools: fact_check (verify a claim), cite_check (verify cited URLs), and source_freshness (check if a source URL is live and its last‑modified date).

How do I get an API key?

Visit the /upgrade page (e.g., ?tier=solo), pay via Dodo Payments, and receive a unique key on the /welcome page. The key is displayed once and can be rotated from the /account page.

Is there a free tier?

Yes. Anonymous callers without an API key can make up to 100 calls per month per IP, with a rate limit of 10 requests per minute.

What data sources does Citation & Source Verification use?

It queries the Wikipedia REST API, Wikidata (CC0), Crossref (free public API), and the Wayback Machine (free public API). The server acts as a caching and auth layer over these sources.
