As answered by people managing DeveloperTools.Tech and VATnode.dev.
VATnode.dev's answer:
vatnode returns the official VIES consultation number for qualified checks — a piece of evidence most commercial VAT validation APIs don't surface. Combined with checkId and verifiedAt fields in every response, it gives finance and engineering teams a defensible record they can store with each invoice. When VIES is unavailable, vatnode falls back to national tax authority APIs across multiple EU countries instead of just failing the check.

Secondary audience: accountants and tax advisors who want a reliable API behind their workflows.
VATnode.dev's answer:
vatnode was built by a Finland-based former CTO with 25+ years of experience shipping B2B software, VAT-aware e-commerce, invoicing systems, and payment integrations across European markets. The recurring pattern in those projects was the same: every commercial VAT validation tool returned a boolean, but finance teams needed an actual paper trail — the kind tax authorities expect when reviewing reverse-charge invoices. vatnode is the API that should have existed years ago: VIES consultation number, structured audit fields, national fallback, EU-hosted, developer-friendly.
