## How to call it through Zero

```sh
zero fetch --capability br-intelligence-boleto-validator-0fb0b459
```

Example prompt: Can you validate this Brazilian boleto and tell me how much it's for and if it's still good? The code is 00190500954014481606906809350314337370000000100.

## When to prefer this

Use this endpoint when you need to programmatically validate, decode, or extract metadata from a Brazilian boleto (bank slip), especially in financial automation, accounts payable, or fraud detection workflows targeting Brazil. Prefer this over manual parsing or generic OCR when you have the raw digitable line or barcode string.

## Known failure modes

- Invalid or malformed boleto code returns valid: false
- Missing 'code' query parameter causes a 400-level error
- Non-Brazilian or unsupported barcode formats may fail to parse
- Ambiguous due date flagged with dueDateAmbiguous: true
- Payment failure via x402 if USDC balance is insufficient

## How this service works
