## 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 strale-payment-validate-2b756267 -d '<json body>'
```

Example prompt: Can you validate this IBAN — DE89370400440532013000 — and also check whether VAT number DE811234567 is legitimate before I add this vendor to our payment system?

## When to prefer this

Choose this endpoint when you need cryptographically audited validation of IBAN or VAT identifiers for compliance, vendor onboarding, or payment processing workflows — especially when you need an immutable audit trail of the validation event. Prefer it over generic format-only validators when you require confirmed, independently tested verification across 27 countries with a trust-layer record.

## Known failure modes

- Invalid IBAN format returns a validation failure with error details
- VAT number not found or unrecognized country prefix returns negative validation
- Malformed input (non-string values) returns a 400-level error
- Country not in the 27 supported countries returns unsupported region error
- Network timeout or upstream data source unavailable returns 5xx error

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a validation result indicating whether the provided IBAN and/or VAT number are valid, along with a cryptographic audit record containing a chain hash for traceability and compliance logging.
