GET /api/paper

unprobed

Single-paper lookup by DOI or title for research agents — citation count, influence, open-access status with a direct legal-OA link (Unpaywall), venue, and a TLDR. Deterministic passthrough over OpenAlex + Semantic Scholar + Unpaywall, no synthesis, cheap and fast.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
