## 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 jithox-e-invoice-readiness-validate-invoice-8a5b6cf6 -d '<json body>'
```

Example prompt: Check if this invoice is ready to send electronically — validate the VAT numbers for buyer DE123456789 and seller FR987654321, verify Peppol routing, and give me a go/no-go decision with any blocking issues I need to fix.

## When to prefer this

Choose this endpoint when you need a single authoritative go/no-go decision on invoice readiness before submitting to an e-invoicing network or tax authority, especially in EU contexts requiring VAT, VIES, and Peppol compliance checks in one call. Prefer it over generic VAT lookup APIs when you need structured blocking-reason output and a signed audit receipt suitable for automated workflows.

## Known failure modes

- Invalid or malformed VAT number format returns an error issue code
- Buyer or seller information missing triggers 'missing_buyer'/'missing_seller' error codes
- VIES service temporarily unavailable may return inconclusive result
- Peppol directory lookup failure may prevent routing validation
- Malformed invoice payload returns HTTP 400 with validation error
- Payment not accepted (insufficient USDC balance) blocks the call entirely

## How this service works

Decision-grade VAT, VIES, Peppol and invoice readiness for AI agents: five read-only MCP tools that return one machine-readable decision with a signed receipt. Public self-service: free trial, then pay per accepted call.

## Output

Returns a JSON object with a 'valid' boolean, an 'issues' array listing each problem (code and severity), and a 'decision' envelope containing canProceed, blockingReasons, warnings, nextActions, and a requiresHumanReview flag, plus a signed receipt confirming the call was processed.
