How billing works

Designed to be predictable at small scale and rewarding at large scale.

01

Pay your monthly minimum

Each paid plan has a minimum commitment (e.g. $99 Growth, $999 Scale). This covers a baseline number of verifications and ensures predictable baseline revenue for SLA maintenance.

02

Only billed on success

Every successful verification beyond the included baseline is billed at your plan's per-check rate. Errors, timeouts, 'not found' responses, and sandbox calls are zero-cost.

03

Volume brackets cut your rate

As monthly successful verifications climb past bracket thresholds, each subsequent batch is billed at the lower rate automatically. No contracts needed — just grow.

Per-verification rates by volume

Brackets apply within each calendar month and reset on the 1st.

Rates apply only to successful verifications. Failed taps, errors, and sandbox calls are never billed. Monthly minimum is charged first; overages are billed at the bracket rates above.
