How this service works
Live Steam best-sellers, deals, per-app detail and IGDB metadata, Twitch hype scores, and agent utilities for verification and extraction. From $0.001 a call, free samples on every endpoint, auth-then-capture. MCP and HTTP.
Output
A JSON object with nested validation results per identifier type: VAT (format_valid boolean), IBAN (valid boolean, country string), and card BIN (scheme string such as 'Visa'). Each field appears only when that identifier type was queried.
Example use cases
Validate customer IBAN before payout
“Before I send this bank transfer, can you verify that GB29NWBK60161331926819 is a valid IBAN and tell me what country it belongs to?”
Check VAT number for invoice compliance
“I need to invoice a new EU client — can you check if their VAT number FR12345678901 is valid and correctly formatted?”
Identify card network from BIN
“I have a card BIN 411111 — can you tell me what card scheme that belongs to, like Visa or Mastercard?”
Technical details
Endpoint
GEThttps://api.borisinc.com/paid/util/finidWhen to prefer
Use this endpoint when you need lightweight, pay-per-call financial identifier validation without setting up an account or API key. Ideal for one-off checks of IBANs, VAT numbers, or card BINs in compliance workflows, invoice processing, or payment routing. Prefer this over full KYC or bank verification services when you only need format and scheme validation, not account ownership confirmation.
Side effects
- Missing or malformed 'input' field returns a 400 error
- Unrecognized identifier format may return format_valid: false without error
- Payment failure via x402 results in 402 response before processing occurs
- Unsupported HTTP method (e.g. POST) returns 405
- Network timeout or upstream data unavailability returns 503
