5 agent-payable APIs. Every listing carries a tested call recipe - endpoint, auth shape, pricing, and known gotchas - on its detail page. ashesborn.cloud ↗
Audit a bibliography: up to 10 references in one call, each DOI string or full citation line. For every item you get the matched paper, its retraction status from OpenAlex and Retraction Watch (Crossref when an update-to notice exists) with tier and date, the retracted papers it depends on, and an explicit unmatched list for anything not in the snapshot. One x402 payment and one round trip instead of ten. Snapshot updated 2026-10-25: 98,868 papers, 572 retraction assertions.
