## How to call it through Zero

```sh
zero fetch --capability certaindata-bin-lookup-5f2e6f10
```

Example prompt: Can you look up the card scheme, type, issuer bank, and country for BIN 424242?

## When to prefer this

Use this endpoint when you need to identify card metadata — scheme, type, brand, issuer, country, and payout settings — from a card BIN prefix. Ideal for payment routing logic, fraud detection enrichment, form auto-fill on checkout, or compliance checks where issuer country matters.

## Known failure modes

- Invalid or malformed BIN returns an error response
- BIN not found in database returns a not-found error
- BINs shorter than 6 digits or longer than 8 digits may be rejected
- Network timeout or service unavailability returns a 5xx error
- Payment failure (x402) if USDC balance is insufficient
