Fingerprint a public page so agents can detect changes: final url, etag, lastModified, sha256 contentHash of normalized visible text, raw byteLength, and fetchedAt. POST JSON {"url":"https://example.com"}. Public http(s) only; private hosts blocked. $0.04 USDC on Base (eip155:8453). No API key.
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
