How this service works
400+ paid API endpoints. Social media, AI, crypto, finance, weather, ecommerce, tools. Pay per request with USDC on Base chain.
Output
Returns structured data about the card including the issuing bank name, card brand (Visa, Mastercard, Amex, etc.), card type (credit/debit/prepaid), card tier, and the country where the card was issued.
Example use cases
Card issuer verification at checkout
“I need to check the BIN 411111 before processing this payment — can you tell me the issuing bank, card brand (Visa/Mastercard/etc.), and whether it's a credit or debit card?”
Fraud detection by card origin
“A transaction came in from card prefix 539146 — can you look up the BIN and tell me what country and bank issued this card so I can flag if it's from an unexpected region?”
Payment form card type detection
“The user entered the card number starting with 378282 — use the BIN checker to identify the card network and type so I can show the right card logo on the payment form.”

Use this endpoint when you need quick, per-request BIN lookups without a subscription to a dedicated BIN database provider. Ideal for AI agents performing fraud checks, payment form enrichment, or card validation on a pay-per-use basis using USDC on Base chain.
Side effects
- Invalid or unrecognized BIN returns empty or error result
- BIN prefix too short or malformed input causes validation error
- Unknown or very new BINs may not be in the database
- Network timeout or service unavailability returns 5xx error
- Payment failure via x402 protocol blocks the request
