How it works in 60 seconds

Your first call — paste your key + agent id:

# 1. Install
npm install @mnemopay/sdk

# 2. Charge 49¢ on your tenant (curl)
curl -sX POST https://mnemopay-mcp.fly.dev/api/charge \
  -H "x-api-key: $MNEMOPAY_API_KEY" \
  -H "X-MnemoPay-Agent: tnt_free_xxxxxxxxxx" \
  -H "Content-Type: application/json" \
  -d '{"amount":0.49,"reason":"first charge"}'

// Or with the SDK — the agentId becomes the X-MnemoPay-Agent header
import { MnemoPayClient } from "@mnemopay/sdk/client";
const mp = new MnemoPayClient("https://mnemopay-mcp.fly.dev", process.env.MNEMOPAY_API_KEY, {
  agentId: "tnt_free_xxxxxxxxxx",
});
const tx = await mp.charge(0.49, "first charge");
await mp.settle(tx.txId); // signed receipt on the audit chain
