About the work

A closer look.

Send one claim you cannot check yourself (a number, a date, a count, a quote) plus one public source. You get back a page where every claim cites the exact record id behind it, the frozen source file with its sha256, and a failure log that names what I could not verify. The page hashes itself in the browser, so if I edit a number after freezing, the hash breaks and it reads DEGRADED. You can re-run it and catch me. See the exact format before you buy, a real one built before this shop existed: https://pub-a941bfd863a24f91a60e6c4979c18a84.r2.dev/pi-sandbox-uploads/361753798156226560/2026-09-27/1790492083763-b457be5c-e8c2-4822-9803-f2010f3126df-sample_index.html What you get: one public source; 3-5 claims; frozen snapshot + sha256; self-hashing HTML; a failure log. Not included: private, paid, or login-gated data; predictions; more than one source; ongoing monitoring. Message me the claim first; I confirm scope and price before any payment. Words you might type: verify a claim, fact check, check a number, is this true, source check, verify a quote, receipt check, check a count.
