Responded
The server completed its last measured handshake. This is an observation, not a guarantee.
Validate a US ABA routing number by its (3,7,1)-weight mod-10 Fedwire/ACH checksum. Catches mistyped or invalid routing numbers before payment; does NOT prevent transfer reversals or establish the recipient. Returns signed XDR-1 receipt.
Measured
Validate an Australian Business Number by its mod-89 checksum (11 digits). Required before invoice payment to Australian contractors. Returns signed XDR-1 receipt.
Measured
Deterministic agent trust scoring and non-custodial unsettled exposure advisory evaluation (ACI-1). Quantifies counterparty grade (T0-T3), historical success rate, and maximum suggested settlement exposure without uncollateralized lending or float.
Measured
One call, one receipt: Kenya KRA PIN + settlement IBAN + SWIFT/BIC. Deterministic structural checks for East African trade corridors.
Measured
Native ETH and one ERC-20 balance (default USDC) for an address on Base, raw and formatted. Result carries a signed receipt.
Measured
Validate up to 50 tax, bank and legal-entity identifiers (IBAN, LEI, VAT, SWIFT/BIC, ABA routing, EIN, IFSC, ABN, GSTIN, ISIN, SEDOL, EAN-13, ISBN, E.164 or Luhn checks) in one batch request. Each result states its scope. Compare the current batch quote with individual quotes; savings depend on batch size.
Measured
Base chain (8453) block header data: block number, timestamp, transaction count and base fee for any block. Result carries a signed receipt.
Measured
Arithmetic comparison of a USDC settlement against comparator percentages YOU supply (bank_fee_pct, custodial_fee_pct) across 14 global fiat currencies. The comparators are assumptions, not measurements of any bank or provider; no protocol fee is deducted on this rail.
Measured
Instant zero-cost pricing hook for code402 tools. Returns the live price, an opaque quote_id, TTL, and the settlement URL. Free forever — feeds the price index into an agent planner's context without creating any financial obligation. If the planner acts on the quote, it hits the settlement_url with an EIP-3009 signed voucher.
Measured
One call, one receipt: USCC + settlement IBAN + SWIFT/BIC for a Chinese counterparty. Deterministic structure and checksum validation with explicit scope per identifier.
Measured
Fetch a public web page by URL (or take your HTML) and return Markdown plus headings. No JavaScript rendering. Result carries a signed receipt.

Measured
Check supported UK company-number syntax. No Companies House lookup, entity-existence check or active-registration verification.
Measured
Deterministic text digest: word count, top-5 most frequent meaningful words (stop words excluded), first sentence, and a keccak-256 content hash. Pure function — no external calls, no ML.
Measured
Create a merchant-direct Base token invoice. New automated payments require a durable EOA authorization journal and a configured provider. No active protocol fee; no generic bank-wire authority, independent delivery or contract-wallet guarantee.
Measured
Spot USD price for a crypto ticker or CoinGecko id from public price feeds, cached 60 s. Result carries a signed receipt.
Measured
Generates cryptographic commitments to commercial terms and formats ERC-5564 dual-key stealth address announcements (CSP-1) for invoice-scale B2B payments on Base L2.
Measured
Validate a phone number's E.164 structure (+CC, 8-15 digits, no leading zero) before dispatching SMS alerts or OTPs. Returns signed XDR-1 receipt.
Measured

Measured
Validate US Employer Identification Number FORMAT (NN-NNNNNNN). Use during US business counterparty KYB verification. Returns signed XDR-1 receipt.
Measured
Raw and formatted ERC-20 balanceOf for an address on Base, with decimals read from the token. Result carries a signed receipt.
Measured
Reference fiat and stablecoin conversion rate from a static table, not a live feed. Returns rate and inverse; result carries a signed receipt.
Measured
Read public recorded invoice status and held-operation next action. Private records and credentials require a separate fresh read-only signature from the durably confirmed original payer; URLs and payment vouchers grant no read authority.
Measured
Validate an Indian GSTIN by structure (2-digit state code + PAN + entity code + 'Z') and its mod-36 cross-sum checksum.
Measured
One call, one receipt: UAE TRN + settlement IBAN + SWIFT/BIC. Deterministic structure validation for Gulf trade corridors, scope stated per identifier.
Measured
Validate IBAN structure and MOD-97 checksum. Does not establish account ownership, beneficiary identity or absence of fraud.
Measured
Check the 11-character Indian IFSC format, including its fifth-character zero. No bank-branch registry lookup or account verification.
Measured
One call, one receipt: GSTIN + PAN + UPI VPA + IFSC for an Indian counterparty. Four deterministic structural checks, each stating its own scope. Built for cross-border procurement where the buyer is an agent that cannot open an INR account.
Measured
Validate JSON data payloads against schema definitions. Preflighted for agent tool call pipelines.
Measured
Validate an ISIN (ISO 6166) by structure and Luhn mod-10 check digit over the A=10…Z=35 converted string.
Measured
Translates validated ISO 20022 payment instructions (pain.001 / pacs.008) into deterministic EIP-712 payment-intent templates for autonomous x402 Base L2 USDC settlement (BAP-1). Zero custody, no fiat leg.
Measured
Deterministic validation for institutional ISO 20022 XML/JSON payment messages (pain.001 credit transfer, pacs.008 customer credit, camt.053 bank statement) with XML DOCTYPE security guards, BigInt CtrlSum decimal sums, and ISO 13616 / 9362 / 17442 checksums (BAP-1).
Measured

Measured
Validate 13-digit Japanese Corporate Number assigned by the National Tax Agency using Mod-9 check digit algorithm. Required for Japanese B2B SaaS and enterprise billing. Returns signed XDR-1 receipt.
Measured
One call, one receipt: 13-digit Corporate Number + settlement IBAN for a Japanese counterparty. Deterministic check digits, explicit scope.
Measured
Validate Kenyan Revenue Authority Tax PIN structure (A/P followed by 9 digits and checksum character). Required for M-Pesa B2B disbursement and Kenyan remote agency invoicing. Returns signed XDR-1 receipt.
Measured
One call, one receipt: Brazilian CNPJ + Mexican RFC + settlement IBAN. Deterministic checks for the two largest LatAm corridors in one paid call.

Measured
Deterministic validation of Indian Permanent Account Number (PAN) issued by CBDT / Income Tax Department with 4th-character entity type classification (Individual, Company, Firm, Trust, HUF).
Measured
Check supplier tax and bank identifiers (IBAN, LEI, EU VAT, UK company number), domain-age evidence and country mismatch signals before vendor payment. Requires a preceding receipt hash. An advisory result is not verified identity, fraud clearance or authorization to release funds.
Measured
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.
Measured
Deterministic reconciliation verdicts: pain.001/pacs.008 instructions vs camt.053 statements or NACHA ACH files, matched by end-to-end id and BigInt-exact amounts. Verdicts: SETTLED, UNPAID, AMOUNT_MISMATCH, DUPLICATE_PAYMENT, plus unmatched statement entries. Facts computed from the documents only — never inferred, never guessed. Returns signed XDR-1 receipt.
Measured
Check deposit IBAN checksum and supplied country/viewing indicators. Rule-based risk signals only; no ownership verification, escrow protection or guarantee against theft.
Measured
Explainable tenancy fraud risk score evaluated across irreversible payment demands, off-platform pressure, stolen photos, and advance wire signals. Deterministic rule engine.
Measured
Combine deposit identifier checks with supplied country, viewing and listing indicators. Does not verify landlord identity, property ownership or safety of payment.
Measured

Measured
Screen an EVM wallet address or ISO country code by exact comparison against the identified sanctions address snapshot and existing operator block policy. Current legal status is unknown; is_sanctioned is null. valid=false preserves a local block; valid=null never authorizes a transaction. Names are not screened. Missing, stale or incomplete evidence is explicit; no UN/EU coverage or sanctions clearance is provided.
Measured
Validate a UK/Ireland security identifier by its (1,3,1,7,3,9)-weight mod-10 checksum. Returns signed XDR-1 receipt.
Measured
Run synthetic prompt-injection halts, malformed-delivery rejection, and bounded-spend eligibility examples under AP2 envelopes. No live escrow, refund, facilitator or chain action occurs.
Measured
Check SWIFT/BIC structure and country code. Does not establish bank existence, active routing or beneficiary identity.
Measured
Deterministic Base contract facts: ERC-20 metadata, proxy slots, owner(), privileged-function selectors and flags. Not a safety verdict. Result carries a signed receipt.
Measured
Outbound transaction count (nonce) and contract-or-EOA check for an address on Base. Result carries a signed receipt.
Measured
Deterministic validation of UAE 15-digit Tax Registration Number (TRN) issued by the Federal Tax Authority (FTA) for VAT purposes.
Measured
Deterministic structural validation of an Indian UPI Virtual Payment Address (VPA / handle): local-part syntax, handle against a LOCAL list of accredited PSP handles (okhdfcbank, okaxis, paytm, ybl and others), and length rules. It is NOT a live registry lookup: no request leaves this worker, and an unlisted handle is reported as unrecognised rather than nonexistent. This does not establish that the VPA is registered, reachable or owned by anyone.
Measured
Validate 18-character Chinese business registration and tax code using GB 32100-2015 ISO 7064 Mod-31-3 checksum. Required for B2B supply chain trade with Chinese manufacturers. Returns signed XDR-1 receipt.
