Agentlink

Appearance

Getting Started ​

Agentlink lets AI agents prove they're backed by a real, verified human so platforms can offer a trusted human-backed tier, selective linked-only access, and softer onboarding when agents pay for services via the x402 protocol.

Think of it as a verified-human badge that agents carry automatically, based on a one-time wallet approval by their owner.

Building an agent? Point it at one file — agentlink.id/skill.md walks an agent through registering, getting human-linked, and calling free partner endpoints.

bash
curl -s https://agentlink.id/skill.md

Then see the Freemium Endpoints it unlocks.

How it works ​

Every path through Agentlink uses the same four-step handshake:

  1. A runtime or platform creates a short-lived owner approval URL.
  2. The agent's owner opens it with their Biomapper-verified wallet.
  3. The service checks on-chain: is this agent linked to an active biomapped human?
  4. The result drives access mode — usually a linked-only tier first, then optional onboarding or paid behavior on top.

Agentlink is live on Base mainnet and Base Sepolia. See Profile Support for current status. Reach out to @tech_digger on Telegram for integration.

Canonical audience map:

Two sides of the marketplace ​

For platform operators and x402 providers — you run the paid route or platform integration, issue hosted approval links, and check verified-human status in real time to decide trusted access, premium plans, and onboarding flows. This is the x402 Service Providers path.

For owner approval and agent operators — you want an agent to carry human-verified status everywhere it pays. Most self-hosted operators are also the owner: you generate the approval URL from your runtime and approve it yourself with your biomapped wallet. Use Self-Hosted Agent Operators for the full path. If you already have the URL and only need the wallet step, use Link Your Agent.

Packages ​

Core library — required for service providers and self-hosted operators:

bash
pnpm add @techdigger/humanode-agentlink

Optional framework adapters — add these if you want native tool surfaces for your agent:

bash
pnpm add @techdigger/humanode-agentlink-langchain langchain   # LangChain
pnpm add @techdigger/humanode-agentlink-ai-sdk ai             # Vercel AI SDK
pnpm dlx @techdigger/humanode-agentlink-mcp                           # MCP server

Not a developer? If your agent runs on a hosted platform, you do not need to install anything. Go to Link Your Agent.

Quick rules of thumb ​

  • Start on base-sepolia while base registry support is being finalized.
  • Start with one linked-only route or feature first, then add free-trial only where a softer onboarding funnel helps conversion.
  • Keep the agent wallet, network, and registry choice inside the runtime or platform that creates the approval URL.
  • If you need LangChain, AI SDK, or MCP adapters on top of the self-hosted path, see Framework Integrations.
  • For the on-chain contract surface, see Contracts Reference.
  • For supported profiles, see Profile Support.
