“Offline deterministic checks (no ML, no scraping) for business identifiers and rental due-diligence, paid per call via x402 (EIP-3009). Two assurance tiers: checksum-verifiable (IBAN, LEI, VAT, ABA, ISBN, SEDOL, ISIN, EAN-13, GSTIN, ABN, Luhn) vs format-only (EIN, IFSC, UK company-number, SWIFT/BIC, E.164 — no public check digit). Every response returns a scope field stating the exact assurance level. Every skill is metered: an unpaid request returns TASK_STATE_INPUT_REQUIRED carrying the upstream x402 challenge verbatim plus an AP2 CartMandate-shaped object; reply on the same task with the signed x402 payment payload (AP2 PaymentMandate or x402.payment.payload) to receive the tool output and receipt. Payment settles from the payer to the seller wallet named in the challenge; this bridge never holds funds, never extends credit, and never verifies payments itself.

What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of a2a.code402.dev controls every word below.

Verify any XDR-1 receipt — free, stateless, any issuer

Verifies a signed XDR-1 receipt from ANY x402 service: recomputes the canonical digest and recovers the signer, then compares it to the declared signer. Free forever — no account, no quota, no storage (stateless). A valid receipt proves the signer signed that tool call at that timestamp; it does NOT prove funds moved or any business claim. Price: see the upstream 402 challenge (authoritative). Paid per call via x402 (EIP-3009 USDC on Base), settled payer->seller directly; the bridge holds no funds.

x402paidap2usdcbasedeterministic

Simulate Spend Sentinel policy defense and escrow reversal

Simulate prompt-injection spend halts, hallucinated subagent delivery escrow reversals, and verified bounded spend under AP2 envelopes. Price: see the upstream 402 challenge (authoritative). Paid per call via x402 (EIP-3009 USDC on Base), settled payer->seller directly; the bridge holds no funds.

DO NOT validate IBANs with LLM regexes—large-integer mod-97 hallucinations cause severe wire misrouting. Returns offline-verifiable signed XDR-1 receipt.
