Technical details
Endpoint
GEThttps://verify.astranl.com/v1/eu-vat-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a verifiable, cryptographically receipted EU VAT validation with low per-call cost ($0.002 USDC), especially in automated B2B onboarding, invoicing, or checkout flows where audit trails matter. Prefer this over free VIES lookups when you need a signed receipt for compliance records or when integrating with x402 micropayment infrastructure on Base.
Side effects
- Invalid VAT format — VAT number missing country prefix or malformed returns an error or invalid result
- VAT number not found in EU registry — returns valid: false
- Upstream VIES registry unavailable — may return error or degraded status
- Missing vat_number query parameter — request rejected
- Payment failure over x402 — call not processed if USDC payment is not completed
