How It Works

Three steps to real-time API settlement

Step 1

Point to Settlex

Change one line of config. Replace the provider base URL with your Settlex gateway URL. Your existing code works as-is.

Step 2

We Proxy & Meter

Every API call flows through our gateway. We authenticate, meter usage, and forward requests to the provider transparently. Zero latency impact.

Step 3

On-Chain Settlement

Your spend is recorded on Canton's ledger and cryptographically verifiable. No invoices, no credit risk.

Switch from direct provider calls to settled API calls by changing the base URL

Before — Direct API call
// Direct call — your API key, your subscription
const res = await fetch(
  "https://pro-api.coinmarketcap.com/v1/cryptocurrency/quotes/latest?symbol=ETH",
  {
    headers: {
      "X-CMC_PRO_API_KEY": "your-cmc-api-key",
    },
  }
);

const data = await res.json();
After — Settled via Settlex
// Through Settlex — one key, usage-based settlement
const res = await fetch(
  "https://settlex-gateway.luganodes.com/gateway/coinmarketcap/v1/cryptocurrency/quotes/latest?symbol=ETH",
