Api Endpoint

factstamp.agentrails.workers.dev

Check a whole bibliography or dependency manifest in one round trip, before you rely on the list: up to 12 items at a flat US$0.12 — 1 cent an item, against 2 cents for the same lookups one at a time. Every item is answered by the same door that answers a single call, so the verdicts cannot disagree. Pay per call here, or redeem a prepaid pack code (one answer-pack credit per three items, up to 25 items on that rail).
