npm install erc-800claw

Quick Start

CLI

# Get agent details
npx erc-800claw agent 1

# Check if agent exists
npx erc-800claw exists 1

# Get agent count for an address
npx erc-800claw owner 0x9ce7082814bDA389F3ba548BDf2626006279569c

# Register a new agent (requires private key)
PRIVATE_KEY=0x... npx erc-800claw register --name "My Agent" --network sepolia

# List networks and contracts
npx erc-800claw networks

# Show contract addresses
npx erc-800claw contracts mainnet

# Use testnet
npx erc-800claw agent 1 --network sepolia

# JSON output
npx erc-800claw agent 1 --json

JavaScript/TypeScript

const { createClient } = require('erc-800claw');

const client = createClient({ network: 'mainnet' });

// Get agent by ID
const agent = await client.getAgent(1);
console.log(agent);
// {
//   agentId: 1,
//   tokenURI: 'ipfs://...',
//   owner: '0x...',
//   metadata: { name: 'My Agent', ... },
//   explorerUrl: 'https://etherscan.io/...'
// }

// Check if agent exists
const exists = await client.agentExists(1);

// Get agent count for an address
const count = await client.getAgentCount('0x...');
console.log(`Address owns ${count} agents`);

// Register a new agent (no IPFS needed - uses data URI!)
const result = await client.registerAgent(process.env.PRIVATE_KEY, {
  name: 'My Autonomous Agent',
  description: 'Handles customer support',
  services: [{ name: 'support', endpoint: 'https://myagent.com/api' }]
});
console.log(`Registered agent #${result.agentId}`);

// Give feedback to an agent
await client.giveFeedback(process.env.PRIVATE_KEY, agentId, {
  value: 4.5,     // Score out of 5
  decimals: 1,
  tag1: 'support',
  tag2: 'fast'
});

API

createClient(options?)

Create a client instance.

const client = createClient({
  network: 'mainnet',  // or 'sepolia'
  rpcUrl: 'https://...'  // optional custom RPC
});

Read Methods

client.getAgent(agentId)

Get agent details by ID. Returns null if agent doesn't exist.

{
  agentId: 1,
  tokenURI: 'ipfs://...' | null,
  owner: '0x...',
  metadata: { ... } | null,  // Fetched from tokenURI if available
  explorerUrl: 'https://...'
}

client.agentExists(agentId)

Check if an agent exists. Returns true or false.

client.getAgentCount(ownerAddress)

Get number of agents owned by an address.

client.getReputation(agentId, options?)

Get reputation summary for an agent.

const rep = await client.getReputation(1, {
  clientAddresses: ['0x...'],  // Required: specific reviewers to query
  tag1: 'support',             // Optional: filter by tag
  tag2: ''
});

client.getNetworkInfo()

Get current network configuration.

Write Methods

All write methods require a private key for signing transactions.

client.register(privateKey, agentURIOrMetadata?)

Register a new agent. Pass a URI string or metadata object (auto-converted to data URI).

// With metadata object (recommended - no IPFS needed)
const result = await client.register(privateKey, {
  name: 'My Agent',
  description: 'Does cool stuff'
});

// With custom URI
const result = await client.register(privateKey, 'ipfs://...');

// Without URI (can set later)
const result = await client.register(privateKey);

client.registerAgent(privateKey, options)

Convenience method with structured options.

const result = await client.registerAgent(privateKey, {
  name: 'My Agent',           // Required
  description: 'Agent desc',  // Optional
  image: 'https://...',       // Optional
  services: [{                // Optional
    name: 'api',
    endpoint: 'https://...'
  }],
  supportedTrust: ['reputation']  // Optional, default: ['reputation']
});
// Returns: { agentId, txHash, owner, explorerUrl }

client.setAgentURI(privateKey, agentId, newURIOrMetadata)

Update an agent's metadata URI.

await client.setAgentURI(privateKey, agentId, {
  name: 'Updated Name',
  description: 'New description'
});

client.giveFeedback(privateKey, agentId, feedback)

Submit reputation feedback for an agent.

await client.giveFeedback(privateKey, agentId, {
  value: 4.5,              // Score value
  decimals: 1,             // Decimal places (default: 2)
  tag1: 'quality',         // Primary category
  tag2: 'fast',            // Secondary tag
  endpoint: '/api/chat',   // Which endpoint was used
  feedbackURI: '',         // Optional: link to detailed feedback
  feedbackHash: '0x...'    // Optional: hash of feedback data
});

Helper Functions

createDataURI(metadata)

Create a data URI from a metadata object (no IPFS upload needed).

const { createDataURI } = require('erc-800claw');
const uri = createDataURI({ name: 'My Agent', description: '...' });
// Returns: data:application/json;base64,...

parseDataURI(dataUri)

Parse a data URI back to a metadata object.

createRegistrationMetadata(options)

Create standard ERC-8004 registration metadata.

What is ERC-8004?

ERC-8004 provides on-chain identity, reputation, and validation for autonomous agents:

• Identity Registry - ERC-721 agent identities with registration metadata
• Reputation Registry - Signed feedback scores between agents/clients
• Validation Registry - Independent verification (zkML, TEE, stakers)
