## 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-invoice-verify-ca-2837f52b -d '<json body>'
```

Example prompt: Can you verify this invoice I received from a Canadian company called Maple Tech Solutions — their VAT number is 123456789RT0001, the sender email is billing@mapletech.ca, the domain is mapletech.ca, and the payment details show IBAN CA12345678901234567890 and BIC ROYCCAT2?

## When to prefer this

Use this endpoint when you need to verify invoices specifically from Canadian companies, combining company registry lookup, tax number validation, banking detail verification, and sender authenticity in a single audited call. Prefer this over generic invoice validators when Canadian-specific compliance (BN/GST numbers, Canadian banking details) is required, or when you need a cryptographic audit trail for each verification for regulatory or internal compliance purposes.

## Known failure modes

- Company name or corporation number not found in Canadian registry — returns not-found status
- Invalid or malformed IBAN format — returns format validation error
- BIC/SWIFT code does not correspond to a known financial institution — returns unrecognized BIC error
- VAT/BN number checksum fails — returns invalid number error
- Sender domain or email unresolvable — returns domain lookup failure
- Incomplete invoice_data object — returns missing fields error
- Rate limiting or payment failure on x402 micropayment — returns 402 or 429 status

## 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 structured verification result indicating whether the Canadian company exists and matches the invoice details, whether the VAT/business number is valid, whether the IBAN and BIC are legitimate and consistent, whether the sender email and domain are authentic, and an audit record with a cryptographic chain hash for compliance traceability.
