Two plans, one difference: volume

How many requests a month, and nothing else. The endpoints, the fields, the country coverage and the response envelope are identical.

A call to GET /v1/vat/{number} that receives an answer. A 400 format error is not counted, since a malformed number is rejected before any source is consulted; neither is a 503, where a member state failed to answer. GET /v1/countries and GET /health never count.

The API answers 429 with the same error envelope as every other code. Nothing is billed on overage: calls resume when the monthly quota renews at the start of the next month.

No. The Free plan takes an email address and gives you 100 requests a month, for as long as you like.

14 € excluding VAT per month, billed monthly. A compliant invoice is issued on every payment, and the reverse charge applies to VAT-registered customers outside France.

Yes, with no notice and no fee. The subscription stays active until the end of the period you already paid for, then falls back to the Free plan.

From official national registers wherever one can be keyed by a VAT number — SIRENE for France, PRH for Finland, RIK for Estonia, the business register for Latvia, and the tax administrations of Poland, Czechia and Romania — and from VIES everywhere else. GET /v1/countries answers with the current list, which is the authoritative one.

Every answer carries meta.sourceUpdatedAt, the timestamp of the record served, and meta.origin, which says whether it came from our database, a national API or VIES — so you never have to assume.
