Pay-per-call has a quiet tax. Somewhere between the ad click and the buyer's phone ringing, a slice of your traffic stops being people. Spoofed numbers, burner VoIP lines, call centers redialing your promos, bots warming up campaigns. Every one of those calls that connects long enough to bill is margin you earned and then handed back.
Today that tax becomes optional. callersift is live.
What it does
callersift sits in the half-second before a call routes. Your call tracker (TrackDrive, Ringba, Retreaver, or anything that can fire a webhook) pings your callersift lookup URL with the inbound caller's number. We score it against carrier-grade phone intelligence and answer allow or block, in milliseconds. Your tracker routes on the answer.
The caller never notices. Your buyers only notice that the calls got better.
Why before the call, not after
Most fraud tooling in this space is forensic: dashboards that tell you on Thursday which of Monday's calls were junk. Useful for clawbacks, useless for margins. Once a fraudulent call hits a payable duration, the money conversation is already an argument.
Screening before the route flips that. The bad call never rings a buyer, never burns a rep's time, never shows up in a dispute thread. One decision, made early, replaces a week of cleanup.
How teams run it
- Networks put callersift in front of buyer routing, so every affiliate's traffic gets the same gate.
- Buyers screen what networks send them and pay only for humans.
- Performance teams use verdicts as a feedback loop: sources with high block rates get fixed or cut.
Setup is one URL and one key. Sign up, pick a plan, paste your lookup URL into your tracker, done. Most teams see their first blocked call within the hour.
Two ways to pay
- Bring your own Integration, $5 a month. Lookups run on your own credentials with your provider. Flat platform fee, 14-day free trial.
- Pay as you go, $0.010 per ping. No integration to bring. Load a balance, we handle the lookups, auto-recharge keeps you covered.
Both plans include the full product: real-time verdicts, the screening dashboard, team seats, and every report.
