Example use cases
Fraud screening by card origin
“A payment just came in with card number starting with 45720132 — can you look up that BIN and tell me what country and issuer it's from so I can check if it matches the customer's stated location?”
Checkout UX card brand detection
“The user typed in the card prefix 5541083 — can you identify the card brand and type so we can show the right card logo and validation rules on the checkout form?”
Payment analytics card type breakdown
“I have a list of BINs from last month's transactions — starting with 411111, can you look up the first one and tell me the brand, issuer, country, and whether it's credit or debit?”

Endpoint
GEThttps://1yc.dev/bin/v1/:bin?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, pay-per-use card BIN lookups without a subscription. Ideal for low-volume or sporadic lookups where only exact matches are charged, avoiding costs for unknown BINs. Prefer over subscription BIN databases when you want zero upfront commitment and per-query pricing via x402.
Side effects
- BIN not found in database — no match returned for obscure or newly issued BINs
- Invalid BIN format — non-numeric or fewer than 6 / more than 8 digits returns an error
- Payment failure — $0.01 USDC charge fails if wallet is not funded
- No partial match returned — only exact BIN matches are billed and returned
