## 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 brasil-dados-api-iban-validation-batch-d5436669
```

Example prompt: Can you check whether the IBAN DE89370400440532013000 is valid and give me a timestamped confirmation?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.001 USDC) mod-97 checksum validation of an IBAN with a timestamped audit receipt — ideal for pre-payment verification flows or compliance logging without needing a full bank account lookup.

## Known failure modes

- Missing or malformed IBAN input returns an error
- IBAN with invalid characters or wrong length fails validation
- Payment not provided or insufficient USDC triggers 402 response
- Service temporarily unavailable on Render cold-start delay

## How this service works

Validate up to 25 IBAN bank account numbers (mod-97 checksum) in a single call. Cheaper per-item than individual requests.

## Output

Returns a validation result indicating whether the IBAN passes the mod-97 checksum, along with a timestamped receipt of the verification.
