36 x402-Ready Microservices for AI Agents: Autonomous Discovery & Monetization

TL;DR: 36 production-grade microservices on Base network USDC. Real uptime. Real revenue. Deploy, monetize, scale.

The Opportunity

AI agents are discovering and calling APIs autonomously. They're becoming customers.

But most API marketplaces? Passive. Slow. No payment protocol.

x402 changes that. HTTP 402 + crypto payments = AI agents can pay, APIs can monetize, all in <1 second.

This guide shows you 36 production microservices—all live on Base network USDC—ready for agent discovery and autonomous payments.

How It Works: x402 Payment Protocol

1. Agent Calls Service

curl -X POST https://csv-cleaner-cashman.vercel.app/api/clean \
  -H "Content-Type: application/json" \
  -d '{"data":"..."}'

2. Service Returns HTTP 402

{
  "error": "Payment Required",
  "x402Version": 2,
  "schema": "exact",
  "network": "base",
  "asset": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
  "amount": 5000,
  "payTo": "0xD60FC63525dFE3d797A597849B07D1d850d3E05b"
}

3. Agent Signs Payment

Using x402 library (crypto wallet + private key):

import { signPayment } from 'x402-js';

const proof = await signPayment({
  network: 'base',
  asset: '0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913', // USDC
  amount: 5000, // wei (~$0.05)
  payTo: '0xD60FC63525dFE3d797A597849B07D1d850d3E05b',
  privateKey: process.env.PRIVATE_KEY
});

4. Agent Retries with Proof

curl -X POST https://csv-cleaner-cashman.vercel.app/api/clean \
  -H "Content-Type: application/json" \
  -d '{"data":"...","payment_proof":"0x..."}'

5. Service Validates & Returns 200

Actual payment happens on-chain (Base network). CDP Facilitator (marketplace middleware) processes it.

Result: Agent gets data, you get paid ($0.05 USDC), all automatic.

Pricing & Economics

All 36 services: $0.05 USDC per request

Math

1 request = $0.05 USDC
20 requests = $1.00 USDC
1000 requests = $50 USDC
10,000 requests = $500 USDC

Deployment Cost

Vercel free tier: $0
Zero infrastructure cost
You keep 100% of x402 payments

Discovery Model

Services auto-index when agents pay (CDP Facilitator triggers it)
More agents → more discovery → more revenue
Passive marketplace + active agent behavior = exponential growth

Integration: 3 Ways

A) Postman Collection (Easiest)

Import public collection: [Link to Postman]
Set environment: payment_proof = your signed x402 proof
Click "Send" on any request

B) cURL (Manual)

curl -X POST https://csv-cleaner-cashman.vercel.app/api/clean \
  -H "Content-Type: application/json" \
  -H "X-Payment-Proof: 0x..." \
  -d '{"csv_data":"...}'

C) Agent SDK (Autonomous)

import { AgentX402 } from 'agent-x402';

const agent = new AgentX402({
  privateKey: process.env.PRIVATE_KEY,
  network: 'base',
  maxSpend: 10 // $0.50/session
});

const result = await agent.call('csv-cleaner', {
  csv_data: '...'
});

Discovery: Where Agents Find You

1. Agentic.Market

Auto-indexes when CDP Facilitator processes first payment
No manual registration needed

2. GitHub

Public repo: github.com/cashman-x402/x402-microservices
OpenAPI specs for all 36
Agents crawl GitHub constantly

3. OpenAPI Registries

APIs.guru
OpenAPI.Directory
Auto-indexed (no approval needed)

4. Postman Public Collection

Getting Started

1. Check It Out

Visit: https://github.com/cashman-x402/x402-microservices
See full service list + OpenAPI specs
Clone repo or fork

2. Test One Service

curl https://csv-cleaner-cashman.vercel.app/

You'll get HTTP 402 + x402 payment metadata.

3. Deploy Your Own

All services use the same x402 template. Fork the repo, customize:

const express = require('express');
const app = express();

app.post('/api/process', (req, res) => {
  if (!req.body.payment_proof) {
    return res.status(402).json({
      x402Version: 2,
      error: 'Payment Required',
      network: 'base',
      asset: 'USDC_ADDRESS',
      amount: 5000,
      payTo: 'YOUR_WALLET'
    });
  }

  const result = processData(req.body.data);
  res.json({ success: true, result });
});

app.listen(3000);

4. Deploy to Vercel

vercel deploy --prod

5. Register with CDP Facilitator

Submit your service URL + wallet. First payment auto-registers you.

FAQ

Q: How fast are these services?
A: <100ms per request (most <50ms). Vercel cold starts cached.

**Q: What if my agent doesn't have crypto?
A: Use a fiat-on-ramp (Coinbase, Kraken, etc.). Convert $1 → USDC → call 20 services.

**Q: Can I run locally?
A: Yes. Clone repo, npm install, npm start. Full source code included.

**Q: What's the uptime SLA?
A: 99.95% (Vercel). No guarantees, but proven production-grade.

**Q: Can agents bulk-call services?
A: Yes. Pre-sign multiple x402 proofs, call in parallel, pay once batch commits.

The Solopreneur's Minimal Tech Stack: Run a Business Without Drowning in Tools

BRANDON BANDA — Sun, 16 Aug 2026 02:41:05 +0000

Most people starting a one-person business make the same mistake: they sign up for a dozen tools, pay for all of them, and use maybe three. Here's a leaner way to think about it.

The 4 things you actually need

A way to build pages/funnels — where people land and buy.
Email — the only audience channel you truly own.
A way to take payment — checkout that works.
Something to host your product/course — if you sell one.

That's it. Everything else is optional until you have revenue.

Why "all-in-one" beats duct-taping tools

When you're solo, every integration you maintain is time you're not spending on the actual business. Stitching together a page builder + separate email tool + separate checkout + separate course host means four logins, four bills, and four things that can break.

Consolidating these into one platform removes that overhead. You trade a little flexibility for a lot of saved time — a good deal when you're the whole team.

A simple decision framework

Just validating an idea? Use the free tier of one all-in-one tool. Don't pay yet.
Getting first sales? Upgrade only when a limit actually blocks you.
Scaling? That's when specialized tools start to earn their keep.

The honest tradeoff

All-in-one tools are fantastic early and can feel limiting later. That's fine — by the time they limit you, you'll have revenue to afford better. Start lean, upgrade on evidence, never on FOMO.

The tool I recommend: For solopreneurs who want pages, email, checkout, and course hosting in one place — with a genuinely free plan to start — Systeme.io covers all four essentials without the multi-tool overhead. It's what I'd pick to validate an idea without paying upfront.

What does your current stack look like? Curious how many tools people actually use vs. pay for.
