How this service works
309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.
Output
Returns a JSON object with ok and paid status fields, and the detected credit card type/network (e.g. Visa, Mastercard, American Express, Discover, JCB, etc.) inferred from the provided card number or schema string.
Example use cases
Payment form card logo display
“I have a card number '5500005555555559' entered in my checkout form — can you figure out what card network it belongs to so I can show the right logo?”
Card type validation before charge
“Before I process this payment, can you tell me what type of credit card '378282246310005' is — I need to confirm it's an Amex before applying the right processing fee.”
Fraud screening card type check
“I need to verify the card brand for number '6011111111111117' — is it Discover? I'm cross-checking it against our fraud rules that differ by card type.”
Technical details
Endpoint
GEThttps://x402-toolbox.shablony-pro.workers.dev/validation/credit-card-type-detect?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, no-signup, pay-per-call credit card type detection without managing API keys. Ideal for AI agents that need on-demand card classification in automated workflows, especially when operating with crypto micropayments (USDC on Base) via x402. Prefer this over full card validation services when you only need brand/network detection, not full Luhn validation or BIN lookup.
Side effects
- Invalid or unrecognized card number format returns an error or unknown type
- Missing schema input parameter results in a bad request response
- Truncated card number with insufficient digits may not be deterministically classifiable
- Network timeout or Cloudflare Worker cold-start delay
