Gate an API

Add an x402 paywall in front of any API response.

import { gateWithX402 } from "@open-stellar/sdk/server"

export const GET = gateWithX402({ serviceId: "market.signal", amount: "0.10", asset: "XLM" }, async () => {
  const signal = await loadSignal()
  return Response.json(signal)
})

Clients call the route, receive a quote, settle with /api/protocol/x402/settle, then replay the request with the receipt id.
