Fact-check and review an AI agent's draft before a human sees it: a hallucination check and second opinion on any email, report, summary, or PR description. Returns pass or specific issues with fixes. Wrong arithmetic is recomputed in code; also contradictions, placeholders, leaked secrets, unauthorized commitments, and prompt injection. Send sources to verify citations and claims against them. Signed receipt. $0.02.

Input

The full text to review, exactly as the human will see it. Up to 48000 characters.
Optional: also fetch the links the draft cites (up to 3 pages in all, +$0.01 each). A cited link that is gone fails the draft.
Optional: let a qualified reviewer from the open review network take this job. Not routed yet: crosscheck's own reviewer does it and the receipt says so.
Optional: the hash of a crosscheck receipt that referred you. Its wallet earns check credits from your first 90 days of spend.
Optional: what the human asked for. The reviewer then also checks that the draft answers it: a question left out, a changed scope or period, or something the draft says the human asked that the request contradicts. Counts toward the size.
Source urls
Optional: up to 3 public web pages crosscheck fetches after payment and checks the draft against. +$0.01 each.
Sources
Optional: the text the draft relies on. Each claim is then checked against it.
