Why GPTBuilder Ads
Revenue you can account for.
Revenue you can account for.
Rewards you can trust.
A focused survey network with the financial and security plumbing a serious reward integration needs.
Surveys worth taking
Filter inventory below your payout threshold, set rating rules and prioritise higher-quality, shorter surveys — with a preference for 1–2 minute completions.
Postbacks that fit
GET or POST, JSON or form data, custom field mapping, HMAC signatures, retries with backoff and delivery logs on every integration.
An auditable ledger
Actual CPX revenue, publisher earnings and platform margin are recorded in an immutable double-entry ledger. Pending, available and reserved are separate.
A graceful empty state
When no qualifying surveys exist, show an optional video fallback. It never creates a reward or publisher earnings — the player can simply continue.
Docs, not archaeology
A lightweight SDK, a clean REST API, server-side verification endpoints and copy-paste postback examples. Ship an integration in an afternoon.
How it works
From application to first reward.
Manual publisher review keeps the network healthy. The technical integration stays deliberately small.
STEP 011
Apply and get approved
Tell us about your game or website, traffic and reward mechanics. We review every integration before it can serve a single survey.
STEP 022
Install the reward gate
Use the lightweight SDK to require a qualifying survey at chosen moments. Explain the reward, let players skip, and never reward a skip.
STEP 033
Verify and get paid
CPX sends a signed completion to our server. We credit your ledger, notify your postback endpoint and release earnings after the hold period.
Built for the people wiring it up
One script. One clear reward moment.
The SDK creates a server-side session, opens the reward overlay and waits for a verified completion. Survey links stay on our domain. Publisher API secrets never enter the browser.
✓Site key identifies the approved integration
✓User ID and custom parameters travel with the session
✓Publisher servers verify completions with a secret API call
✓Reversal and retry events are part of the contract
