Licensing & SDK

Sell your software, we handle the keys. After a webhook-confirmed payment we issue a license key; your software validates it against our API on launch. Keys are machine-bound and tied to the buyer's subscription — access ends automatically on cancellation, expiry, or refund.

How it works

1Customer buys your app — Stripe processes the payment.
2Our webhook confirms it and issues a unique license key instantly.
3Customer pastes the key into your software (or we provision web/TradingView/Discord access).
4Your software calls POST /api/licenses/validate on launch; bind to machine on first use.
5We keep the key valid while the subscription is active — and revoke it when it isn't.
