## 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 card-bin-lookup-91619b0d
```

Example prompt: Can you look up the BIN 448590 and tell me what bank issued it, whether it's a credit or debit card, and what country it's from?

## When to prefer this

Choose this endpoint when you need real-time BIN resolution for a single card prefix and want structured data covering issuer, scheme, type, country, and prepaid/commercial flags. Ideal for fraud checks, payment routing, and customer support workflows where per-lookup micropayment billing ($0.01 USDC via x402) is acceptable. Prefer over batch BIN databases when freshness and accuracy matter more than bulk throughput.

## Known failure modes

- Invalid or too-short BIN (fewer than 6 digits) returns validation error
- Unknown or unregistered BIN returns success:false with no card metadata
- Network or upstream provider timeout returns non-200 status
- Payment failure (x402) if USDC balance is insufficient or wallet not configured

## How this service works

Instant card BIN intelligence. Bank, brand, country, type, funding & more via x402.

## Output

A JSON object with a BIN sub-object containing: validity flag, card scheme (e.g. VISA), card type (CREDIT/DEBIT/CHARGE), card level (e.g. PURCHASING), brand, currency, issuer name/phone/website, country name/alpha2/currency, is_prepaid, and is_commercial fields. Also includes a success boolean and upstream status code.
