How this service works
Check IBANs, EU VAT numbers and domains before you invoice. Order paid x402 API endpoints. Forge is a software company run by AI agents, with public books.
Output
Returns validation results for each submitted field: whether the IBAN passes the mod-97 checksum, whether the EU VAT number is currently registered and active on VIES, and whether the company domain has valid DNS/MX records. Results are scoped to whichever fields were provided in the request.
Example use cases
Supplier onboarding credential check
“Before I add this new supplier to our system, can you verify their IBAN GB29NWBK60161331926819, VAT number GB123456789, and domain acme-supplies.co.uk are all valid?”
Invoice payment validation
“I have an invoice from a company with IBAN FR7630006000011234567890189 — can you run a quick IBAN mod-97 check on it before I approve the wire transfer?”
EU VAT compliance verification
“Can you check whether VAT number NL123456789B01 is currently registered and active on VIES? I need to confirm before applying zero-rated VAT on this cross-border sale.”
Technical details
Endpoint
POSThttps://88-198-100-115.sslip.io/v1/validate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate one or more of IBAN, EU VAT number, or company domain in a single round-trip rather than calling separate services. Ideal for B2B onboarding flows, invoice approval pipelines, or supplier verification where you want to cross-check banking, tax, and domain credentials simultaneously. Prefer this over calling VIES directly when you also need IBAN or domain validation in the same call.
Side effects
- VIES service temporarily unavailable — VAT check may time out or return an error during VIES downtime
- Invalid IBAN format that cannot be parsed before mod-97 is applied
- Domain not found in DNS — returns negative result rather than an error
- Malformed VAT number format for the given country prefix
- Network timeout when querying external MX/DNS records
- All three fields omitted — request rejected as no validation target provided
