Docs — live in three steps

DropIn is a single script plus two API calls. No backend, no SDK build step.

Add the embed

Paste this into your <head>. It exposes window.dropin.

<script
  src="https://dropin.aiskillhub.info/dropin.js"
  data-key="pk_demo_dropin"
></script>

Declarative — no JS needed:

<button data-dropin-checkout="pro" data-dropin-currency="inr">
  Upgrade to Pro
</button>

Or imperative:

dropin.checkout("lifetime", "usd");

After purchase, call dropin.activate(licenseKey). Then gate anywhere:

const { entitled } = await dropin.gate("pro");
if (!entitled) {
  dropin.checkout("pro", "inr");
} else {
  renderProFeature();
}

Licenses are HMAC-signed and verifiable from your own backend:

curl "https://dropin.aiskillhub.info/api/entitlement?key=DROPIN-...&feature=pro"
# -> { "entitled": true, "plan": "pro" }

GET /api/health returns { status, version, uptime } for uptime monitors.
