aixyz for openclaw Users

This guide is written for openclaw users who want to ship a live, paid AI agent using aixyz. You do not need prior coding experience or knowledge of crypto infrastructure — every step is explained from scratch.

Quick reference: The general aixyz skill lives at skills.sh/agentlyhq/aixyz. Consult it for full CLI flags and advanced topics. This guide focuses on the path that matters most to openclaw users.

What You Are Building

An AI agent that:

1. Runs on the internet at a public URL
2. Accepts work requests from other agents (A2A protocol) and from AI clients like Claude Desktop (MCP protocol)
3. Gets paid per request in crypto via the x402 micropayment protocol
4. Is discoverable on-chain via the ERC-8004 registry

Step 1 — Install Bun

aixyz requires Bun (not Node). If you already have Bun ≥ 1.3, skip this step.

# macOS / Linux
curl -fsSL https://bun.sh/install | bash

# Windows (PowerShell, requires WSL or Windows 10+)
powershell -c "irm bun.sh/install.ps1 | iex"

Verify:

bun --version   # should print 1.3 or higher

Why Bun? The aixyz build pipeline uses Bun's native build API and plugin system — this is a hard architectural requirement, not a preference. The CLI (@aixyz/cli) cannot run on Node. Bun also includes a built-in test runner, which means no extra test framework is needed. Curious about the full rationale? Read Why Bun.

Step 2 — Scaffold Your Agent

# Create a new agent project (uses all defaults)
bunx create-aixyz-app my-agent --yes

cd my-agent

This creates:

my-agent/
  aixyz.config.ts   ← agent name, description, payment config
  app/
    agent.ts        ← your AI agent logic
    tools/          ← tool files (optional)
  package.json
  .env.local        ← API keys (never commit this file)

Open .env.local and add your LLM provider's API key. The default scaffold uses @ai-sdk/openai, so add:

OPENAI_API_KEY=sk-...

If you prefer a different provider (Anthropic, Google, Amazon Bedrock, etc.), swap the @ai-sdk/* adapter in package.json and app/agent.ts, then set the corresponding env var instead. See ai-sdk.dev for the full list of providers.

Run locally to test:

bun run dev
# Agent is now live at http://localhost:3000

Testing with an AI agent client? Install the use-agently skill so your AI agent can call your local agent in dev mode:

npx skills add https://github.com/agentlyhq/use-agently --skill use-agently

This skill lets any AI agent discover and call your locally running agent at http://localhost:3000. While testing locally, set "scheme": "free" so callers are not charged (see Step 7). Before going to production, switch to "scheme": "exact" so your agent earns from every request.

Step 3 — Deploy to the Internet

Your agent needs a public HTTPS URL so other agents and clients can reach it. If you already have a preferred hosting platform, use it. If you are starting fresh, here are our recommendations.

Option A — Vercel (recommended, no server knowledge needed)

Vercel gives you a free HTTPS URL with zero configuration. It is the easiest path.

1. Push your project to a GitHub repository
2. Go to vercel.com → Add New Project → import your repo
3. Set the Build Command to bun run build and the Output Directory to .vercel/output
4. Add your LLM provider API key (e.g., OPENAI_API_KEY) in the Vercel dashboard under Settings → Environment Variables
5. Click Deploy — Vercel gives you a URL like https://my-agent.vercel.app

Vercel auto-deploys on every push. Your agent is serverless and scales automatically.

Option B — Railway / Render / Fly.io (persistent server)

Use these if your agent needs to hold state between requests or run background jobs.

For all three: push your repo, connect the platform, set your LLM provider API key (e.g., OPENAI_API_KEY) as an environment variable, and follow their deploy wizard. They all detect Bun automatically.

Option C — Cloud Platform Ingress or Local Tunnel (advanced)

If you are already running OpenClaw on a cloud platform (AWS, GCP, Azure, DigitalOcean, etc.), the simplest path is to expose the agent through that same platform:

• AWS — use an Application Load Balancer or API Gateway in front of the process
• GCP — use Cloud Run (zero-config container deploy) or a load balancer
• Azure — use Azure Container Apps or App Service
• DigitalOcean — use App Platform or a Droplet with nginx as a reverse proxy

🔒 Least-privilege rule: When exposing the agent process, only open the port the agent listens on (default 3000). Do not grant the process broader network, IAM, or filesystem access than it needs to serve HTTP requests.

If you just need a quick tunnel for local testing, use ngrok:

# ngrok — creates a public HTTPS URL that forwards to localhost:3000
npx ngrok http 3000

⚠️ Security warning: Local tunnels are fine for short-lived testing but should never be used for a production agent. Anyone who discovers the URL can send requests to your machine. Always use a proper hosting provider for live traffic.

Step 4 — Get a Crypto Wallet

You need a wallet to:

• Receive payments from callers of your agent
• Pay gas fees when registering on ERC-8004

Option A — Use use-agently (simplest, recommended for openclaw users)

use-agently is the simplest wallet for the aixyz ecosystem. It is designed for the circular economy of agents paying agents.

When prompted during aixyz erc-8004 register, select "Generate a new wallet" and the CLI will create one for you and display the private key.

🔐 Private key security — read this carefully:

• Never share your private key with anyone. Anyone who has it controls your funds.
• Never commit it to git or paste it in public channels (Discord, Slack, GitHub, etc.).
• Write it down offline and store it somewhere safe (e.g., a password manager).
• For a production agent that earns significant income, consider a hardware wallet (Ledger, Trezor).

Option B — MetaMask (browser extension)

1. Install MetaMask in your browser
2. Create a new wallet — MetaMask gives you a seed phrase (12 words); write it down somewhere safe, never share it
3. Copy your wallet address (starts with 0x…)

Option C — Any EVM-compatible wallet

Any wallet that supports Ethereum-compatible networks works: Coinbase Wallet, Rabby, Frame, etc.

Your wallet address is your "bank account number." You share it publicly. Your private key / seed phrase is your password — never share it, never commit it to code.

Step 5 — Get Crypto for Registration

Registering on ERC-8004 costs a small gas fee (a fraction of a dollar). You need the native coin of your chosen network.

Recommended network: Base. The x402 payment facilitator is primarily deployed on Base, so your agent will receive payments most reliably there. Base also has very low gas fees — registration typically costs a few cents. Ethereum mainnet gas varies widely and is usually not worth it for getting started. Gas prices on all networks can fluctuate; the amounts above are rough guides only.

Steps to fund your wallet:

1. Create an account on any exchange above (identity verification required)
2. Buy a small amount of the relevant coin (a few dollars is enough for registration)
3. Withdraw to your wallet address
4. Wait for the transaction to confirm (~1–5 minutes)

No crypto yet? You can still build and run your agent locally and on Vercel without registration. Register once you are ready to be publicly discoverable.

Step 6 — Register on ERC-8004

ERC-8004 is an on-chain registry that makes your agent discoverable by other agents, platforms, and users. It is like a DNS entry but for AI agents.

Once your agent is deployed (Step 3) and you have a funded wallet (Steps 4–5), run:

# Interactive mode (will prompt you for each setting)
aixyz erc-8004 register

# Non-interactive mode (all values as flags)
aixyz erc-8004 register \
  --url https://my-agent.vercel.app \
  --chain base \
  --broadcast

The CLI will ask for (or accept as flags):

See all flags:

aixyz erc-8004 register --help

After registration, your agent appears in the ERC-8004 registry and becomes discoverable by the ecosystem.

Step 7 — Set Up Payments

Add an accepts export to app/agent.ts so callers are charged per request:

import type { Accepts } from "aixyz/accepts";

// During local testing — callers are not charged
export const accepts: Accepts = { scheme: "free" };

// Production — callers pay $0.005 per request
// export const accepts: Accepts = { scheme: "exact", price: "$0.005" };

Testing tip: Use "scheme": "free" while developing and testing locally (install the use-agently skill to call your local agent from an AI client). Before going to production, switch to "scheme": "exact" with a price so your agent earns from every request.

Set the wallet address that receives payments in aixyz.config.ts:

export default {
  name: "my-agent",
  // ...
  x402: {
    payTo: "0xYourWalletAddress", // ← paste your address from Step 4
  },
} satisfies AixyzConfig;

Or pass it at scaffold time:

bunx create-aixyz-app my-agent --yes --pay-to 0xYourWalletAddress

Payments flow directly to your wallet — no platform takes a cut.

Step 8 — Go Live Checklist

Before announcing your agent, verify:

• bun run dev works locally and the agent responds correctly
• Agent is deployed to a public URL (Vercel or similar)
• LLM provider API key (e.g., OPENAI_API_KEY) and any other secrets are set as environment variables on the platform, not committed to your repo
• aixyz.config.ts has the correct name, description, and payTo address
• ERC-8004 registration is complete and the registry shows your agent URL
• accepts export is set so your agent earns from requests

Step 9 — Market Your Agent

Registration is only half the work. Getting on-chain doesn't automatically bring users. You need to actively promote your agent.

Make it discoverable

• Write a clear, specific description in aixyz.config.ts — this appears in the A2A agent card and on-chain registry
• Add an app/icon.png — a good icon makes your agent stand out in listings
• Post your agent URL and ERC-8004 agent ID in the openclaw community

Reach potential callers

• Share your /.well-known/agent-card.json URL — it is the standard entry point for agent-to-agent discovery
• Add your agent to relevant directories and marketplaces (check aixyz.sh for current listings)
• Write a short demo showing what your agent does and how much it costs — post on X/Twitter, Farcaster, or Discord communities

Think about pricing

• Too expensive → no callers; too cheap → not worth running
• Start with $0.001–$0.01 per request and adjust based on demand
• Monitor your wallet — incoming transactions tell you who is using your agent and how often

Keep improving

• Add more tools to make your agent more useful
• Respond to issues and feedback
• Update your on-chain registration if your URL changes: aixyz erc-8004 update --help

Troubleshooting

"command not found: bun"

Restart your terminal after installing Bun, or run source ~/.bashrc (Linux) / source ~/.zshrc (macOS).

"API key is not set" / "OPENAI_API_KEY is not set"

Add your LLM provider's API key to .env.local (local dev) or to your platform's environment variable settings (production).

"Transaction failed" during ERC-8004 registration

Your wallet does not have enough gas. Add a few more dollars of the relevant coin and retry.

Agent is deployed but not responding

Check that your platform's build command is bun run build and that all environment variables are set. Check the platform's deploy logs for errors.

Payment not arriving

Verify your payTo address in aixyz.config.ts is correct and that you rebuilt and redeployed after changing it.
