● healthy

Use before you name a company in a contract or quote a number you did not compute yourself. FactStamp returns verified, stale, contradicted or unknown, cited to a dated primary source, with an Ed25519-signed receipt that verifies offline. $0.02-$0.05 a call in USDC on Base, or drawn from a prepaid pack bought by card. Unknown is a first-class answer, never a guess.
