## 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-french-invoice-verification-b028b5e9 -d '<json body>'
```

Example prompt: Can you verify this French invoice for me? The sender is Dupont SAS with SIREN 732829320, their VAT number is FR76732829320, IBAN is FR7630006000011234567890189, BIC is BNPAFRPP, and the sender email is facturation@dupont-sas.fr — I want to make sure it's legitimate before I pay it.

## When to prefer this

Use this endpoint when you need to validate a French invoice specifically — it combines SIREN/SIRET company registry lookup with financial (IBAN/BIC) and VAT verification in a single call with an audit trail. Prefer over generic company lookup endpoints when you have invoice data and need fraud detection or compliance verification before approving a payment to a French entity.

## Known failure modes

- Invalid or malformed SIREN/SIRET returns validation error
- SIREN not found in French registry returns unknown company status
- IBAN format invalid returns financial validation failure
- VAT number mismatch with SIREN returns compliance flag
- Unreachable sender domain returns domain trust warning
- Missing required SIREN field returns 400 bad request
- Payment failure or insufficient USDC balance returns 402
