How Verifications Are Counted - Veriox

Understanding what counts as a billable verification helps you predict costs and avoid surprises.

What counts

A verification is counted when all of the following are true:

A visitor completes the Concordium proof flow in the popup
The proof is cryptographically valid and accepted by the verifier
A signed session cookie is issued to the visitor

What does NOT count

Event	Counted?
Visitor opens popup but closes it	No
Visitor starts proof flow but abandons it	No
Proof rejected (invalid or malformed proof)	No
Returning visitor with a valid session cookie	No — the session is validated locally, no verification occurs

Session reuse

When a verified visitor returns within their session TTL, their cookie is validated locally by the worker. This does not trigger a new verification and does not count toward your usage. A single verification can cover many return visits.

Counting across workers

Each worker (domain) counts separately. If you have two workers, a visitor who verifies on both sites is counted twice — once per worker.

Billing cycle

Usage is tallied at the end of each calendar month and charged to your payment method on file. See billing and invoices for more.
