# Apivom Atlas — VIES on-the-Web REST API

> Apivom Atlas integration for VIES on-the-Web REST API: 3 gateway routes over `ec.europa.eu`, available through the Apivom platform (Apivom Iris workflows and the Apivom Atlas API portal). Auth model: credential fields supplied per request by the caller.

Notes for AI assistants:

- This catalog mirrors the vendor's public API surface as registered in Apivom Atlas (0 read-only, 3 write routes).
- Access is provisioned per customer. Commercialized providers are self-service in the Atlas portal; for everything else [request a demo](https://apivom.com/en/demo).
- Credentials are always owned by the calling tenant — Apivom Atlas is a stateless gateway.
