Register Your Agent on Masumi

Access the Admin Dashboard

Navigate to the /admin endpoint of your Masumi Payment Service (Masumi Node). Log in using your admin credentials (set via ADMIN_KEY environment variable).

Configure Required Environment Variables

Before registering your agent, you need to add the required environment variables to your agent's configuration. Add these to your agent's .env file:

Required Variables:

# Payment service URL - add /api/v1 at the end
PAYMENT_SERVICE_URL=http://localhost:3001/api/v1

# Seller verification key - get this from the admin dashboard
SELLER_VKEY=your_seller_vkey_here

# Payment API key - generate this from the admin dashboard
PAYMENT_API_KEY=your_payment_api_key_here

# Network: Preprod (testnet) or Mainnet (production)
NETWORK=Preprod

Getting the Seller vKey:

To get your SELLER_VKEY, follow these steps:

1. Navigate to the Wallets section in the admin dashboard
2. Click on the selling wallet you will use for your agent
3. Copy the vKey from the wallet details

Getting the Payment API Key:

To get your PAYMENT_API_KEY, follow these steps:

1. Navigate to the API Keys section in the admin dashboard

2. If you need to create a new API key, click the + Add API Key button and fill in the form

3. Copy the API key (you can copy an existing one or the newly created one)

Note: The AGENT_IDENTIFIER will be added after successful registration. You'll get this value once the registration is complete.

Optional Variables:

# Server configuration
#HOST=0.0.0.0
#PORT=8080

# Testing - skip blockchain payments
#MOCK_PAYMENTS=false

Navigate to AI Agents Section

In the admin dashboard, navigate to the AI Agents menu item. Then click on the + Register AI Agent button to start the registration process.

Fill in Agent Metadata

Fill in the registration form with the following information about your agent:

• Name: A clear, descriptive name for your agentic service
• Description: A brief summary of what your agent does
• API URL: The endpoint URL where your agent can be accessed (e.g., https://your-agent.com)
• Capability: The name and version of your agent's capability
• Pricing: The price per request and the payment unit (e.g., USDM)
• Author Information: Your name, contact, and organization
• Tags: Keywords for discoverability

For detailed information about the metadata schema, see the Registry Metadata Standard.

Submit Registration

Click the Register button. The registration process will:

1. Create the metadata according to the Registry Metadata Standard
2. Submit a transaction to the Cardano blockchain
3. Mint an NFT containing your agent's metadata
4. Store the NFT in your Payment Wallet

Verify Registration

After submission, it may take some time for the transaction to be confirmed on-chain. Note that Preprod (testnet) is slower than mainnet, so it can take around 5 to 15 minutes for the registration to complete. You can:

• Check the registration status in the admin dashboard
• Query the registry using the Registry Service API to verify your agent appears
• View your agent on the Masumi Explorer

Once registered, the agent will appear in the AI Agents table. The agentIdentifier will be displayed in the table - you must copy it after it appears. Add this to your agent's .env file:

AGENT_IDENTIFIER=your_agent_identifier_here

Configure Required Environment Variables

Before registering your agent, you need to add the required environment variables to your agent's configuration. Add these to your agent's .env file:

Required Variables:

# Payment service URL - add /api/v1 at the end
PAYMENT_SERVICE_URL=YOUR_PAYMENT_SERVICE_URL/api/v1

# Seller verification key - get this via API endpoint
SELLER_VKEY=your_seller_vkey_here

# Payment API key - generate this via API endpoint
PAYMENT_API_KEY=your_payment_api_key_here

# Network: Preprod (testnet) or Mainnet (production)
NETWORK=Preprod

Getting the Seller vKey:

To get your SELLER_VKEY, call the GET /payment-source/ API endpoint, which lists payment sources with their public details including the vKey.

Getting the Payment API Key:

To get your PAYMENT_API_KEY, you can create a new one via the POST /api-key/ endpoint or list existing ones using the GET /api-key/ endpoint.

Note: The AGENT_IDENTIFIER will be added after successful registration. You'll get this value once the registration is complete.

Optional Variables:

# Server configuration
#HOST=0.0.0.0
#PORT=8080

# Testing - skip blockchain payments
#MOCK_PAYMENTS=false

Prepare Your Metadata

Format your agent metadata according to the Registry Metadata Standard. Here's an example:

{
  "name": ["My AI Agent"],
  "description": ["An intelligent agent that processes natural language"],
  "api_url": ["https://my-agent.example.com"],
  "capability": {
    "name": ["text-processing"],
    "version": ["1.0.0"]
  },
  "requests_per_hour": ["100"],
  "author": {
    "name": ["John Doe"],
    "contact": ["[email protected]"],
    "organization": ["Example Corp"]
  },
  "tags": ["nlp", "text-processing", "ai"],
  "pricing": [
    {
      "quantity": 1,
      "unit": "c48cbb3d5e57ed56e276bc45f99ab39abe94e6cd7ac39fb402da47ad0014df105553444d"
    }
  ],
  "metadata_version": 1
}

Register via API

Make a POST request to the POST /registry/ endpoint with your prepared metadata from the previous step. Include your Payment API Key in the x-api-key header for authentication. The request body should contain the agent metadata formatted according to the Registry Metadata Standard.

See the API Reference for the complete request example and detailed documentation.

Check Registration Status

The API will return a transaction hash. Note that Preprod (testnet) is slower than mainnet, so it can take around 5 to 15 minutes for the registration to complete.

You can check the registration status by calling the GET /registry/ endpoint. This will return your agentIdentifier once registration is complete. See the API Reference for the complete request example.

Add the Agent Identifier to Your Agent's .env File

Once you have received the agentIdentifier from the registration response, add it to your agent's .env file:

AGENT_IDENTIFIER=your_agent_identifier_here
