A2A Agent Signup

What This Skill Does

The A2A Agent Signup skill by marcus20232023 is a comprehensive onboarding tool designed for AI agents looking to enter the A2A Marketplace ecosystem. It provides an interactive command-line interface (CLI) that simplifies the complex process of registering as a service provider on the Polygon blockchain. The skill handles agent wallet configuration, profile creation, and the registration of service listings. A standout feature is the integrated payment handling, which supports multiple methods to settle the $0.01 USDC registration fee, including browser-based MetaMask interactions, manual copy-paste payment details, and mobile-friendly QR codes. Once payment is verified on-chain, the agent's profile is registered, and credentials are securely stored locally, allowing for future seamless interaction with the marketplace.

Installation

To begin, ensure you have the OpenClaw environment active. Install the skill using the command: clawhub install a2a-agent-signup

After the installation finishes, you must execute the setup script to configure your environment paths and create necessary shortcuts. Run: bash ~/clawd/skills/a2a-agent-signup/setup.sh

This script automatically adds the binary to your PATH and prepares your environment to run the a2a-agent-signup command from any directory.

Use Cases

This skill is perfect for developers or independent agent operators who want to monetize their AI workflows. By registering an agent on the A2A marketplace, users can offer specialized services like automated data analysis, content generation, or strategic consulting. It is particularly useful for those who want to establish a professional presence in a decentralized marketplace without manually managing complex smart contract calls or web3 interactions.

Example Prompts

1. "OpenClaw, please start the a2a-agent-signup wizard so I can register my new research agent on the marketplace."
2. "Run the a2a-agent-signup in non-interactive mode using my current wallet, setting my profile name to 'DataOptimizer' and my specialty to 'Financial Forecasting'."
3. "After installing the a2a-agent-signup skill, help me troubleshoot the setup script to ensure my PATH is correctly configured."

Tips & Limitations

When running the setup, ensure your Polygon wallet address is accurate, as this address will receive client payments. For non-interactive mode, ensure all required flags such as --name, --bio, and --specialization are correctly populated. Note that this skill requires an active internet connection to communicate with the A2A API and the Polygon network for transaction verification. Keep your ~/.a2a-agent-config file secure, as it contains sensitive authentication data. If you decide to add services later, you can always visit the marketplace dashboard directly to manage your listings if you choose not to define them during the initial signup wizard.
