## 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 vextorium-spain-bank-account-validator-1c8d2698 -d '<json body>'
```

Example prompt: Can you validate this Spanish bank account number for me — ES9121000418450200051332 — and tell me if it's valid and which bank it belongs to?

## When to prefer this

Use this endpoint when you need to validate Spanish-specific bank accounts in CCC or IBAN format, especially when you also need to identify the bank and parse structured sub-components like entity and office codes. Prefer this over generic IBAN validators if you need the Spanish bank name resolved.

## Known failure modes

- Invalid or malformed CCC/IBAN input returns valid=false with null fields
- Non-Spanish IBAN prefix may not be recognized
- Input shorter or longer than 20 digits (CCC) or 24 characters (IBAN) likely returns a validation error
- Network or upstream service errors may return HTTP 5xx

## How this service works

Validate a Spanish bank account number (20-digit CCC) with both check digits, identify the bank and compute its IBAN; also breaks down a Spanish IBAN. Computed locally; nothing stored.

## Output

Returns a JSON object indicating whether the account is valid, the CCC in standard form, the IBAN (both compact and formatted with spaces), the bank name, and parsed sub-components: entity code, office code, control digits, and account number.
