## 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 1yc-dev-bin-lookup-f250db5f
```

Example prompt: Can you look up the BIN 453201 and tell me what card brand, issuing bank, country, and card type it belongs to?

## When to prefer this

Use this endpoint when you need fast, pay-per-use card BIN lookups without a subscription. Ideal for low-volume or sporadic lookups where only exact matches are charged, avoiding costs for unknown BINs. Prefer over subscription BIN databases when you want zero upfront commitment and per-query pricing via x402.

## Known failure modes

- BIN not found in database — no match returned for obscure or newly issued BINs
- Invalid BIN format — non-numeric or fewer than 6 / more than 8 digits returns an error
- Payment failure — $0.01 USDC charge fails if wallet is not funded
- No partial match returned — only exact BIN matches are billed and returned

## How this service works

Card BIN lookup: brand, issuer, country and type for a 6 to 8 digit BIN. Only an exact bundled match is charged.

## Output

Returns the card brand (e.g. Visa, Mastercard), issuing bank name, country of issuance, and card type (e.g. credit, debit, prepaid) for the provided 6-8 digit BIN. Only exact bundled matches are charged.
