Developers · Centhead

Quick start

Create an account, open Developers in the app and register your app. Choose the percentage of each payout you keep and list the origins that may embed the widget.
Store the secret key on your server. It is shown once.
On your server, request a token for the signed-in user (below).
On your page, mount the widget with that token.

1. Server: mint a one-time token

const res = await fetch('https://centhead.com/api/v1/embed-tokens', { method: 'POST', headers: { authorization: 'Bearer ' + process.env.CENTHEAD_SECRET, 'content-type': 'application/json', }, body: JSON.stringify({ external_user_id: String(user.id) }), }); const { token } = await res.json(); // valid for 10 minutes, single use

2. Page: mount the widget

<div id="earn"></div> <script src="https://centhead.com/sdk/centhead.js"></script> <script> const widget = Centhead.mount('#earn', { getToken: () => fetch('/my-backend/centhead-token').then(r => r.json()).then(j => j.token), onEarned: (e) => console.log('viewer earned', e.viewerFormatted), }); </script>

How it behaves

The ad runs in Centhead’s own frame. Only origins you registered can embed it (enforced with frame-ancestors).
Viewers confirm they are 18+ and accept the terms inside the widget, and see the exact split before each ad.
Viewers earn into a pseudonymous account keyed to your user id, and can claim and withdraw it from a full Centhead account with a one-time code.
You never see a viewer’s balance, and you cannot trigger ads or earnings from your side.
Your share is held and reversed together with the payout it came from.

Rules

Do not reward viewers for clicking or for extra views, and do not generate views yourself. Apps that do are suspended and earnings forfeited.
Do not target children. See the Integrator Terms.
Never expose your secret key in a browser or mobile app binary.
