# Card BIN Lookup

> Card BIN Lookup is a paid API for AI agents from x402.agentutility.ai, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Looks up card network metadata (type, scheme, issuing country) from a payment card BIN/IIN prefix

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-c674a756 -d '<json body>'
```

Example prompt: Can you look up the BIN 411111 and tell me whether it's a credit or debit card, which network it's on like Visa or Mastercard, and what country it's issued from?

## When to prefer this

Use this endpoint when you need to classify a payment card by its BIN prefix — especially for fraud checks, routing logic, or checkout UX that needs to display the card brand and type. Prefer this over full card validation services when you only have the first 6-8 digits and need quick network/type/country metadata.

## Known failure modes

- Invalid or unrecognized BIN returns empty or null result
- BIN not found in database returns no card type or scheme
- Malformed input (too short/long prefix) may return an error
- Payment failure via x402 if insufficient USDC balance
