Two-sided offerwall network

Only pay for
what’s real.

of/fair is the offerwall ad network where advertisers pay only for verified completions and publishers monetize with a rewarded offerwall. Every conversion is confirmed server-to-server, via your MMP or our signed S2S, then screened by a five-layer fraud pipeline.

For advertisers

Buy outcomes, not impressions

Fund a campaign, define the checkpoints that matter, and pay only when a real user hits them.

  • Pay per verified install or in-app event
  • Multi-checkpoint offers (install, level 3, purchase)
  • AppsFlyer & Adjust, or our own signed S2S
  • Budgets, caps, and fraud protection built in
For publishers

Monetize with a rewarded offerwall

Drop in a JSON feed or a hosted webview, set your own exchange rate, and reward users on approval.

  • JSON offer feed or hosted HTML offerwall
  • Set your own reward exchange rate per app
  • Reward-granted callback on every approval
  • Transparent earnings, conversions & payouts
How it works

One clean loop, verified end to end

From offer to reward, every step is server-authoritative. The client is only ever a trigger.

01

Advertiser posts an offer

A rewarded task with budget, targeting, and one or more checkpoints: install, reach level 3, make a purchase.

02

We serve the right users

Eligible offers only. Targeting, budget and frequency caps are enforced server-side, ranked deterministically.

03

Completion is verified

Every checkpoint is confirmed server-to-server, via your MMP or our signed S2S, then screened for fraud.

04

Everyone gets paid, fairly

The user is rewarded, the publisher earns their share, and we take a transparent, configurable cut.

Verification

Two ways to prove it, one source of truth

Attribution comes in through the source you already trust: your MMP pushes postbacks, or you send our HMAC-signed S2S. Each campaign has one primary source; the other corroborates, never a second payout.

  • AppsFlyer & Adjust ingested as a verified partner
  • Our own /v1/postback: HMAC-signed, replay-proof
  • Deduped by a single idempotency key
  • MMP fraud flags fold in as signals, not sole truth

Your demand, extended to partner networks

of/fair can act as a demand source for other networks. Partners consume your eligible offers through a signed feed plus an S2S and pull conversion API, net of our margin, governed by per-partner rules. More verified reach for advertisers, with the same clean pipeline end to end.

Why of/fair

Built like infrastructure, not an afterthought

Verified-only billing

Conversions are confirmed server-to-server and pass fraud checks before payout. No spend on phantom installs.

Five-layer fraud pipeline

Signature and replay checks, dedup, structural validation, velocity limits, then human-reviewable adjudication, with versioned, explainable rulesets.

Money that never drifts

Every amount is an exact integer micro-unit with an explicit currency. No floating-point rounding across millions of micro-payouts.

Multi-checkpoint offers

Split a reward across events, install, level 2, level 3, each paying its own verified amount.

Attribution your way

Ingest AppsFlyer and Adjust as a partner, or send our signed S2S. One primary source per campaign.

A demand source, too

Syndicate demand outward to partner networks through a signed feed and conversion API, net of margin.
