Bank Data
Bank Data validates IBANs and looks up SWIFT/BIC codes worldwide, and can also break an IBAN down into its country-specific structure or list every major bank and branch code for a given country. It's an APILayer marketplace product sharing that ecosystem's dashboard, `apikey`-header auth, and billing with siblings like Fixer and Tax Data, with a persistent free tier (100 requests/month, no card) below metered paid plans running up to 60,000 requests/month.
GreatAPIs Score
Auth quickstart
- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
Developer reference
Free trial tier: 100 requests/month; paid tiers each choose a configurable per-month/per-day rate limit at signup (exact paid-tier numbers not publicly listed)
