humanode-agentlink
AgentLink gives an AI agent a verified, human-backed on-chain identity. Use it to link and register an agent wallet with a biomapped human owner in BiomapperAgentRegistry, verify active AgentLink status on Base mainnet, sign HTTP requests with the agent key, validate agentlink headers, and access supported partner endpoints. Covers the AgentLink CLI encrypted keystore and external signers through the SDK.
Why this skill is useful
Adds executable scripts for signing HTTP requests and managing on-chain identities that the AI cannot generate on its own.
What it needs
Requires @techdigger/humanode-agentlink, @techdigger/humanode-agentlink-cli installed locally. Requires biomapper account access. About 4k tokens when loaded. Last updated 2026-08-07. 405 stars on the source repository.
What this skill does
AgentLink Skill AgentLink gives an AI agent a verified, human-backed on-chain identity. With this skill the agent can sign any HTTP request, appear in the on-chain registry as a trusted agent, and access free partner endpoints on Base mainnet. Skill Condition An agent holds the AgentLink Skill when both are true: Linked & registered — the agent wallet is linked to a biomapped human owner, which is the same on-chain write that registers it in the BiomapperAgentRegistry. agentlink status --network base --json reports "linked": true and "active": true. Signing — the agent can produce a valid agentlink header, signed by the agent key (held in the encrypted CLI keystore, or by an external signer for the SDK). --- Phase 1 — Acquire Run the CLI with npx (no global install needed) and store your agent private key. No on-chain write happens yet — registration is created during the Linker step in Phase 2. Prefer a global install? npm install -g @techdigger/humanode-agentlink-cli makes the agentlink command available directly (this guide uses the short agentlink ... form from here on). For CI or secret-manager flows use --private-key-stdin instead of the interactive keystore. --- Phase 2 — Verify The human owner must complete biomapping and link their wallet to the agent. The agent cannot complete this phase alone — it generates a URL for the human to open. Human prerequisites The human owner must do these two steps first: 1. Open Biomapper and complete biomapping. 2. Bridge their biomapping to Base. Generate the Linker URL Replace 0x<OWNERADDRESS> with the human owner's biomapped wallet address: This prints (and optionally opens) a self-contained URL. Send it to the human owner. They open it, review the request in the AgentLink Linker at app.agentlink.id, and sign the link transaction. Confirm the skill is active When the JSON output shows "linked": true and "active": true, the skill is acquired and Phase 2 is complete. active tracks the owner's biomapping. …
