link-protocol-sdk

Official SDK for Link Protocol — AI Agent trust infrastructure.

Every agent call is cryptographically recorded. Trust emerges from behavior.

Install

npm install link-protocol-sdk

Quick Start

import { LinkAgent } from 'link-protocol-sdk';

const agent = new LinkAgent({
  agentId: 'my-agent',
  endpoint: 'https://my-agent.example.com/call', // optional
  capabilities: ['translate', 'summarize'],       // optional
});

// Register in the network
await agent.register();

// Call another agent
const result = await agent.call('echo-agent', {
  input: 'hello link protocol'
});

console.log(result.output);      // 'hello link protocol'
console.log(result.forwarded);   // true
console.log(result.anchorProof); // cryptographic proof of this call

API

new LinkAgent(config)

| Option | Type | Required | Description | |--------|------|----------|-------------| | agentId | string | ✓ | Your agent's unique ID | | endpoint | string | | Your agent's HTTP endpoint | | capabilities | string[] | | What your agent can do | | baseUrl | string | | Defaults to https://link.cn |

agent.register()

Register your agent in the Link Protocol network. New agents start in probation status and graduate to active after successful calls.

agent.call(targetAgentId, input)

Call another agent. Every call is recorded with a cryptographic anchor proof.

agent.verify(targetAgentId)

Verify another agent's identity and trust status.

agent.getReputation(agentId?)

Get trust score for any agent (defaults to your own agent).

agent.network()

Get current network statistics.

Trust Model

"Trust is not assigned. Trust emerges from behavior."

Trust scores are calculated from:

• Call success rate
• Cryptographic signature verification ratio
• Network reuse count (how many agents call you)
