Bank Data API

API

Instant global IBAN and SWIFT number validation API

Overview

The Bank Data API offers RESTful endpoints for real-time validation of IBANs and SWIFT/BIC codes across 200+ countries. Key endpoints include /validate/iban (checks structure, checksum, and bank details) and /lookup/swift (retrieves institution info like name and location). Responses are JSON-formatted, delivering actionable data to verify bank details. Ideal for fintech apps, payment gateways, and accounting tools to reduce transaction errors, prevent fraud, and ensure compliance with global banking standards by validating details upfront.
