How this service works
Identify a payment card from its BIN/IIN (Bank Identification Number — the leading 6-8 digits). Pass the BIN or the first digits of a card number and get the card brand (Visa, Mastercard, …), card type (debit/credit), category, issuing bank, and country (ISO alpha-2 + name). Longest-prefix match against an open community dataset (CC-BY). The BIN identifies the issuer/brand/country only — never the cardholder or account number. For payment routing, fraud checks, and checkout UX.
Output
Returns a JSON object with ok status and an items array containing the matched BIN record including brand (e.g. VISA, MASTERCARD), cardType (CREDIT/DEBIT), issuer bank name, bank URL if available, country name and ISO alpha-2 country code, and query metadata showing the input and matched BIN. Also includes a source object crediting the open dataset used.
Example use cases
Example prompt
“Can you look up the BIN 424242 and tell me what card brand it is, whether it's credit or debit, which bank issued it, and what country it's from?”
Technical details
Endpoint
GEThttps://2s.io/api/finance/binWhen to prefer
Use this endpoint when you need to identify a payment card's brand, type, issuer, or origin country from its leading digits — particularly when no API key or signup is desired and pay-per-call micropayment via USDC is acceptable. Prefer over scraping or manual lookup when programmatic BIN resolution is needed in an agent workflow.
Side effects
- BIN not found in dataset — found: false returned with empty issuer fields
- Invalid or too-short BIN string — may return no matches
- Network or payment failure via x402 — 402 Payment Required if USDC not sent
- Malformed query parameter — 400-level error
