Paste the full JSON response from /api/iso-receipt. Everything runs in your browser — no API key, nothing leaves this page except a read-only lookup of the transaction on a public chain RPC.
What this proves: the artifacts are byte-identical to what OnchainPulse signed (Ed25519, published key at /.well-known/receipt-signing-key.json), the bundle hash is correctly derived from its contents, and the referenced transaction really exists on chain with the stated block. Generated from public chain state; not a bank-issued document.
