Why we charge per successful verification

By The Authevo Team5 min read

Most verification pricing punishes you for things outside your control. You get billed for every send attempt, every retry, and every undelivered message — so when a carrier drops traffic, you pay for the failure. We took the opposite stance: we center your bill on the outcomes you actually get, not on every attempt — with a transparent per-message starting tier while a new account builds history (more below).

One number: $0.01 per success

A verification is “successful” when the code is delivered and the user enters it correctly. On the pay-per-success tier that single event costs $0.01, and failed deliveries, expired codes, and wrong guesses don’t. New accounts start on a per-message tier — $0.006 per message sent — until their first 500 successful verifications, then switch to pay-per-success automatically. Either way, there’s no monthly subscription on top.

Prepaid credit, no subscriptions

No card is required to sign up, and your first 50 verifications are free. When you’re ready to send to real users, you add prepaid credit and draw it down as you verify — top up from your dashboard via InstaPay and we credit your balance, usually within 30–60 minutes. A $2 minimum balance keeps sending active. The credit tiers:

  • Prepaid credit in $5, $20, $50, and $100 tiers — the balance never expires into a subscription.
  • No seats and no monthly tiers — a side project and a scaling startup pay the same per-success rate.
  • Spend only as you grow — credit draws down per verification, so cost tracks real usage.

The Safety Floor keeps abuse off your bill

Pay-per-success could be gamed by floods of junk traffic, so the Safety Floor watches for abuse patterns and runaway spend and throttles suspicious requests automatically. It protects your balance from bots without you configuring anything.

The result is an incentive we’re happy to live with: we only earn when your users actually get verified. If WhatsApp delivery slips, that’s our problem to fix — not a line item we quietly bill you for.
