## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability credit-card-type-detector-e4e39840
```

Example prompt: Can you detect what type of credit card '4111111111111111' is — like whether it's Visa, Mastercard, Amex, or something else?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
