Proof that the world changed the way your agent says it did. One live probe of a public URL against your expectation (HTTP status, keyword, CSS selector, JSON path), answered synchronously as an Ed25519 signed verdict that embeds a signed observation: final URL, resolved address, TLS certificate fingerprint, response headers, raw body sha256, timestamp. A stake free witness against false success, priced to clear unattended wallet caps. $0.25 per verdict, no account.

Pay and retry with any x402 client: npx x402-fetch 'https://umpire.vimabrosta.com/v1/verdicts/witness'
