## 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 x402-hub-bin-checker-c2dfcedf -d '<json body>'
```

Example prompt: Can you look up the BIN details for the card prefix 424242 — I need to know the issuing bank, card type, and country?

## When to prefer this

Choose this endpoint when you need lightweight, per-lookup BIN validation or card issuer identification without subscribing to a full KYC or payment processing service. Ideal for agent workflows requiring pay-per-use card metadata enrichment at $0.05 per call, especially when verifying card origin or type before processing transactions.

## Known failure modes

- Invalid or incomplete BIN prefix returns empty or error data
- BIN not found in database returns null or empty data object
- Malformed query parameter causes a 400 or validation error
- Payment failure via x402 micropayment returns 402 Payment Required
- Upstream BIN database unavailable causes 500 or timeout
