The browser fetches the public Ed25519 key from `.well-known`, hashes the report body, and verifies the signature locally.
Endpoint verification report generated from mapper + payments ledger.
Signature over the SHA-256 hex digest of the report body.
39.6M x402 transactions since April 2026, read live from Base.
Half the volume is wash, decomposed by a transparent 4-rule heuristic — not an accusation.
58,903 endpoints mapped across registries; ~77% still declare the legacy network identifier.
Hover any segment. „unclassified" is classification coverage, not unknown garbage.
This is the part a conventional analytics dashboard does not carry: query, methodology, snapshot, signature, and local verification.
No signup. No dashboard account. Machine-readable evidence over x402.
Returns a signed payer trust score derived from on-chain behavior. Heuristic, reproducible, Ed25519-signed.
