Variable Layer Platform
Variable Layer is the canonical data layer for Polkadot 2.0. Embed real-time JAM core utilization, XCM flows, governance status, and account data into any parachain site, dApp, or forum with a single line of code.
No Auth Required
All public endpoints are open. No API keys, no registration. Rate-limited at 60 req/min per IP.
CORS Enabled
Every endpoint sends unrestricted CORS headers — embed directly from any browser or client-side app.
Real-Time SSE Streams
Push events for core updates, XCM transfers, and governance votes. No polling required.
TypeScript SDK + CLI
npm install @variablelayer/sdk or npm install -g @variablelayer/cli to get started in 30 seconds.
Webhook Delivery
Register HTTPS endpoints to receive push notifications. HMAC-signed, auto-retried, failure-tracked.
Drop-in Widgets
React components with dark/light/cyber themes and four size presets. Zero configuration required.
