POST /paid/verify-citations

live

Batch citation check for a whole document, up to 10 citations per call, with the same verdicts and verbatim evidence as /verify-citation. Sources are deduplicated before fetching, so many claims against one paper cost one render. Flat rate: below about 8 citations the single endpoint is cheaper.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
