## 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 bin-checker-api-25eabcca -d '<json body>'
```

Example prompt: Can you look up the BIN details for card prefix 424242 and tell me what bank issued it, what card type it is, and what country it's from?

## When to prefer this

Use this endpoint when you need quick, per-request BIN lookups without a subscription to a dedicated BIN database provider. Ideal for AI agents performing fraud checks, payment form enrichment, or card validation on a pay-per-use basis using USDC on Base chain.

## Known failure modes

- Invalid or unrecognized BIN returns empty or error result
- BIN prefix too short or malformed input causes validation error
- Unknown or very new BINs may not be in the database
- Network timeout or service unavailability returns 5xx error
- Payment failure via x402 protocol blocks the request
