## 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 bic-format-validator-088f0620
```

Example prompt: Can you check if the BIC code DEUTDEDB is correctly formatted and tell me what country letters it contains?

## When to prefer this

Use this endpoint when you need to verify that a BIC is structurally correct and extract its embedded country letters before processing a payment or financial transaction. It is a lightweight, low-cost format check, not a live bank lookup — prefer it when you only need format validation, not confirmation that the bank exists.

## Known failure modes

- BIC shorter or longer than 8 or 11 characters returns a format error
- Non-alphabetic or invalid characters cause a validation failure
- Missing 'code' query parameter returns a bad request error
- Network timeout for edge cases

## How this service works

Call when an agent has a BIC and needs the format result and the country letters. Does not confirm the bank.

## Output

Returns the format validation result for the provided BIC (pass/fail or checksum result) and the two-letter country code letters embedded in the BIC. Does not confirm whether the bank actually exists.
