A CHECK IS NOT A COMPLETION
Most fraud vendors bill per completion — one finished interview, no matter how many people entered and screened out along the way. We bill per check, at the door, because that is where the check is useful: catching someone after they have finished your survey is too late.
To compare like for like, multiply our rate by your entries per complete. At four — a common ratio, though only you know yours:
- Growth, Server-Side
- 0.8¢
- per completed interview
- Starter, Server-Side
- 1.6¢
- per completed interview
- Typical incumbent
- 2¢ – 10¢
- per completed interview
NO SURPRISES IN THE BILL
- Overage costs the same as the plan
- Go past your included checks and the rate does not change — 0.4¢ on Starter, 0.2¢ on Growth. There is no penalty rate and no cliff.
- Screening the same person repeatedly is free
- We bill at most five Server-Side checks per respondent per month. Check someone at every question if you like — past five, it costs nothing. More checks give us better signal, so charging you for them would be backwards.
- A check we could not run is not billed
- If no signal reached us, the response comes back unmeasured and free. You are never charged for a verdict we did not have the evidence to give.
HONEST COMPARISON
How VerifyHuman differs from the tools you already know.
Most survey-fraud tools are device-fingerprint or behavioral screeners — good at spotting a suspicious device or behavior, but they never confirm a unique, present person. The vendors that do are biometric — and of those, VerifyHuman is the one that runs the face check on the respondent's own device, so no image is ever sent to a server.

Compiled from each vendor's public materials, May 2026. RelevantID = Imperium (device fingerprinting); Research Defender = Rep Data (device + behavioral + open-end NLP; no biometrics); Sentry = CloudResearch (behavioral + DigiPrint device ID); CleanID = OpinionRoute (device / network); Roundtable = behavioral proof-of-human; Verisoul = server-side face match (uploads and stores a selfie photo + video for up to 3 years). Vendors' own accuracy figures are their claims, not independent tests. Spot something wrong? Tell us — we'll fix it.
