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 decision envelope with: a 'valid' boolean, a 'normalized' VAT number string, an 'issue' field (e.g. 'none'), and a nested 'decision' object containing 'status' (e.g. 'ready'), a human-readable 'summary', 'canProceed' boolean, 'warnings' array, 'blockingReasons' array, 'nextActions' array, and a 'requiresHumanReview' boolean — plus a signed receipt for audit purposes.
Example use cases
Pre-invoice VAT check for new customer
“Before I issue the invoice, check if VAT number DE811197711 is valid and VIES-registered — I need to know if I can proceed or if there's a problem I should flag.”
Automated AP onboarding validation
“We just received a supplier form with VAT number FR40303265045 — can you verify it's valid and invoice-ready so we can approve their vendor account?”
Bulk e-invoicing readiness audit
“I'm about to send e-invoices to a new Dutch client with VAT number NL123456782B01 — validate it against VIES and tell me if there are any blocking reasons or if it's good to go.”
Technical details
Endpoint
POSThttps://mcp.jithox.com/x402/mainnet/paycall/tools/validate_vat_number?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, machine-readable go/no-go decision on a VAT number — not just a raw VIES API response. It is ideal for AI agents that need to autonomously decide whether to proceed with invoicing without human intervention, as it returns normalized data, warnings, and blocking reasons in a single signed response. Prefer it over raw VIES lookups when you need auditability, structured decision logic, or Peppol/e-invoice readiness context alongside the VAT check.
Side effects
- Invalid VAT format returns a decision with canProceed=false and blockingReasons populated
- VIES service unavailability may cause lookup failure or timeout
- Unsupported country prefix returns an error or unresolvable decision
- Malformed request body returns a 4xx error
- Payment failure (insufficient USDC) blocks the call before validation occurs
