Settle via xerpaai-go

Goal: move from dry-run to real settlement through the xerpaai-go /user/onchainos/* API. xpense never signs or holds keys — it calls that API with a scoped JWT.

Steps

1. Authenticate — await xpense.login() (see Authentication).
2. Set mode — XAGENT_PI_MODE=live (or new Xpense({ mode: "live" })). Only live settles real money.
3. Get the gateway — const gw = await xpense.gateway(). JWT is injected and auto-refreshed.
4. Check the wallet — await gw.walletStatus().
5. Settle — gw.x402Sign(...) for HTTP-402 resources, or gw.mppCharge(...) for machine-payment deduction.

const gw = await xpense.gateway();

await gw.walletStatus();
const signed = await gw.x402Sign({ accepts, resource: "/api/inference" });
const charged = await gw.mppCharge({ challenge });
