Banking & Payments Validators Suite

by Info Inlet Inc.

Validate every payment identifier before money moves: IBAN, BIC, SWIFT, US ACH routing numbers, AU.

Banking & Payments Validators Suite — Validate every payment identifier before money moves: IBAN, BIC, SWIFT, US ACH routing numbers, AU BSB, credit-card numbers (Luhn + scheme), card BIN lookup, and EU VAT numbers. Deterministic, reproducible, audit-friendly.

🏦 Rules-based — NOT AI

🚀 Newcomer launch pricing — limited-time introductory rates while we earn our first reviews.

Built for fintech developers, accounts-payable and payments teams, billing and treasury platforms.

Why this exists

A single mistyped IBAN, routing number, or VAT ID causes failed payments, compliance flags, and costly reconciliation — and each check ships from a different vendor.

What you get

One API key validates every banking and payment identifier with check-digit and scheme rules, plus card BIN lookups, in one consistent response shape.
