Quinn's Conveyance puts APIs behind HTTP 402 (the x402 protocol) so agents pay per call in USDC on Base — no API keys to issue, no signup forms, no cards, no invoicing, no billing stack to build. The wallet is the identity; the payment is the authorization.

This repo is the working proof: the live demo's source, and the SDK we ship to clients.

Live proof

  • Demo — an MCP server with 5 paid tools at $0.005/call: demo.quinnsconveyance.com
  • Insights — every challenge and settlement, public: demo.quinnsconveyance.com/insights
  • Settlement proof — a real mainnet payment, settled via Coinbase CDP: Basescan
  • Listings — Coinbase Bazaar + Agentic.market (all 5 tools), MCP Registry (io.github.jkomalleyjr/quinns-conveyance), PayAI Bazaar

The SDK — quinns-x402

The same code the demo runs, packaged. Paywall an Express API or an MCP server in minutes:

npm install quinns-x402
import { x402, createSettlementLogger } from "quinns-x402";

const logger = createSettlementLogger(process.env.DATABASE_URL!, { verify: true });

app.use(x402({
  payTo: "0xYourBaseWallet",               // settlements land here, directly
  price: "$0.005",
  resourceBaseUrl: "https://api.yourco.com",
  routes: { "GET /api/weather": { description: "Current weather for a city" } },
  onChallenge: logger.onChallenge,
  onSettlement: logger.onSettlement,
}));

What you get beyond the official @x402 packages:

  • Dual facilitators — Coinbase CDP (JWT auth) or PayAI, one config line
  • Discovery built in — Bazaar extension declared automatically; your endpoints index after their first paid call
  • A settlement ledger — every 402 challenge and settlement in Postgres: payer wallet, amount, latency, conversion funnel
  • Verification on every settlement — Flow Executor's 4 checks (signature, nonce, transfer log, validity window) recorded as verify_status, fail-open-but-loud, with a delayed re-check that corrects propagation-race false failures

How the demo works

demo/server.ts — an Express + MCP (StreamableHTTP) server. Paid calls flow: 402 challenge → EIP-3009 signed authorization → facilitator settlement on Base → response. Settlements are logged to Postgres, verified, and rendered on the public Insights dashboard. Payments settle directly to the operator's wallet — the service never holds funds.

Services
Implementation$500 flat — one API behind 402, dual facilitators, MCP wrapper, registry/Bazaar listings, settlement logging. Waived with a 12-month Operate plan.
Operate Core$150/mo — settlement logging & monitoring, facilitator failover, monthly agent-traffic report.
Operate Insights$350/mo — Core plus the live analytics dashboard.

Pilot program (3 slots): free implementation + 90 days of Operate Insights, in exchange for a logo, a quote, and a case study with real numbers. Terms: sales/pilot-agreement.md · sales/pilot-offer.md

Writing

Principles

  • No custody, ever. Settlements go straight to the API owner's wallet.
  • Customer data is never sold. The settlement database exists to operate and improve the service — it is not a data product.
  • Measure commerce, not transaction counts.
