How this service works
14 paid financial API endpoints. Pay with USDC on Base using x402 protocol.
Output
Returns structured data about the BIN including the issuing bank name, card brand (Visa, Mastercard, etc.), card type (debit/credit/prepaid), and country of issuance.
Example use cases
Fraud screening before payment processing
“Before we process this transaction, check BIN 453201 — I need to know the issuing bank, card type, and whether it's from a high-risk country.”
Card validation for e-commerce checkout
“At checkout a customer entered a card starting with 545454 — can you verify what bank and card network that BIN belongs to so we can validate it?”
Analytics on card origin for reporting
“I have a list of card BINs from last month's transactions — start with BIN 411111 and tell me the issuing bank, card brand, and country so I can tag it in our reports.”
Technical details
Endpoint
POSThttps://x402-alert.vercel.app/api/bin-checkerWhen to prefer
Use this endpoint when you need fast, per-call BIN lookups with micropayment pricing via USDC on Base (x402 protocol), especially for agent workflows that need pay-as-you-go card validation without a subscription. Prefer this over subscription BIN databases when call volume is low or unpredictable.
Side effects
- Invalid or unrecognized BIN returns empty or error result
- BIN not found in database returns no data
- Malformed input (non-numeric or too short) causes request failure
- Payment failure via x402 protocol blocks the request
- Network timeout on Vercel serverless function
