Added "aba_routing_check", "abn_check", "aci_trust_lookup" and 30 more (24 tools before, 57 now)
ABA Routing Number Check (US Fedwire/ACH) — 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.

ACI-1 Agent Credit & Trust Rating Lookup — 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.

Get B2B invoice status — 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.

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.
Rental Deposit Risk Indicators — Check deposit IBAN checksum and supplied country/viewing indicators. Rule-based risk signals only; no ownership verification, escrow protection or guarantee against theft.
Rental Listing Risk & Fraud Engine — Explainable tenancy fraud risk score evaluated across irreversible payment demands, off-platform pressure, stolen photos, and advance wire signals. Deterministic rule engine.

India UPI Virtual Payment Address (VPA) Validator — 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.
China USCC Check (Unified Social Credit Code / 统一社会信用代码) — 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.

IBAN Structure and Checksum Check — Validate IBAN structure and MOD-97 checksum. Does not establish account ownership, beneficiary identity or absence of fraud.
IFSC Format Check — Check the 11-character Indian IFSC format, including its fifth-character zero. No bank-branch registry lookup or account verification.
