Marketplace Service Template

Turn AI agent traffic into passive USDC income.

Fork this repo → edit one file → deploy → start earning.

You provide the idea. We provide 148 mobile devices across 6 countries (DE, PL, US, FR, ES, GB), x402 payment rails (Solana + Base), and the marketplace to find customers.

Reference implementation included: This repo ships with a working Google Maps Lead Generator (src/service.ts + src/scrapers/) built by @aliraza556. Use it as-is or replace with your own service logic.

The Economics

You're arbitraging infrastructure. Buy proxy bandwidth wholesale, sell API calls retail.

Proxy cost: flat $4/GB — one simple rate, all 6 countries, mobile + residential (live pricing). Duration is free; you only pay for the GB you actually use.

Your margin depends on what you're scraping:

Use Case	Avg Size	Reqs/GB	Cost/Req	You Charge	Margin
JSON APIs	~10 KB	100k	$0.00004	$0.001	97%
Text extraction	~50 KB	20k	$0.0002	$0.005	96%
HTML (no images)	~200 KB	5k	$0.0008	$0.005	84%
Full pages	~2 MB	500	$0.008	$0.02	60%

Example: Text scraper at 10k req/day

• Traffic: ~0.5 GB/day → $2/day proxy cost
• Revenue: $0.005 × 10k = $50/day
• Profit: $48/day (~$1,400/mo)

Key: Optimize response size. Return text, not full HTML. Skip images. The template's proxyFetch() returns text by default (50KB cap).

Why This Works

1. AI agents pay automatically — x402 protocol, no invoicing, no chasing payments
2. Real mobile IPs — bypass blocks that kill datacenter scrapers
3. Zero customer support — API works or returns error, agents handle retries
4. Passive income — deploy once, earn while you sleep

Quick Start

# Fork this repo, then:
git clone https://github.com/YOUR_USERNAME/marketplace-service-template
cd marketplace-service-template

cp .env.example .env
# Edit .env: set WALLET_ADDRESS + PROXY_* credentials

bun install
bun run dev

Test it:

curl http://localhost:3000/health
# → {"status":"healthy","service":"my-service",...}

curl http://localhost:3000/
# → Service discovery JSON (AI agents read this)

curl "http://localhost:3000/api/run?query=plumbers&location=Austin+TX"
# → 402 with payment instructions (this is correct!)

Edit One File

src/service.ts — change three values and the handler:

const SERVICE_NAME = 'my-scraper';       // Your service name
const PRICE_USDC = 0.005;               // Price per request ($)
const DESCRIPTION = 'What it does';      // For AI agents

serviceRouter.get('/run', async (c) => {
  // ... payment check + verification (already wired) ...

  // YOUR LOGIC HERE:
  const result = await proxyFetch('https://target.com');
  return c.json({ data: await result.text() });
});

Everything else (server, CORS, rate limiting, payment verification, proxy helper) works out of the box.

Security

Built in by default:

• On-chain payment verification — Solana + Base RPCs, not trust-the-header
• Replay prevention — Each tx hash accepted only once
• SSRF protection — Private/internal URLs blocked
• Rate limiting — Per-IP, configurable (default 60/min)
• Security headers — nosniff, DENY framing, no-referrer

See SECURITY.md for production hardening.

Open Source, Public Good (fixed $SX bounties discontinued)

This is an open-source, community-maintained project (MIT). Build and run useful public scrapers on shared mobile-proxy infrastructure — for the public good and for your own benefit.

Your income comes from your customers, not from us. When AI agents call your service, they pay you USDC directly via x402 — you keep 100% of that (see "The Economics" above). That is the real, honest upside, and it's uncapped: a good service earns while you sleep.

Fixed $SX bounties are discontinued. We no longer post guaranteed-amount bounties. Instead:

• Discretionary $SX rewards. We may grant $SX to maintainers whose contributions we find genuinely valuable — at our discretion, when warranted. It is a thank-you for outstanding work, not a promised or guaranteed payout. Don't build expecting a fixed reward; build because the service earns you USDC and is useful.
• Existing submissions made under the previous bounty terms will be reviewed and handled in good faith — see the pinned transition notice in Issues.

AI agents welcome. Fork it, build a clean public scraper, deploy it, and maintain it. Open a PR or a "New Service" issue. The bar is real, useful, well-documented services — quality over quantity.
