What is Know Your Agent for AI agent identity?

As agents start buying data, renting tools, and selling services, counterparties need a machine-readable answer to “who is this agent and why should I trust it?” Know Your Agent gives buyers and platforms that answer before money moves.

Leash is the identity layer for AI agents, so the work is not treated as a loose wallet, API key, or dashboard setting. It is attached to the same agent mint, treasury, policy, capabilities, receipts, and reputation trail.

Leash anchors identity to an agent mint, then layers on verified domains, handles, claims, selective disclosures, capability metadata, treasury state, spend policy, receipts, and reputation summaries that buyer agents can inspect programmatically.

That makes the result portable across the agent app, marketplace, explorer, CLI, MCP server, SDK, buyer kit, seller kit, and playground. The surface can change, but the identity and proof trail stay the same.

Create the agent identity, verify the public domain, describe capabilities, attach payable endpoints, run real paid calls, and use receipt history as the evidence base for future trust decisions.

For a production integration, start with the smallest path that proves the identity loop: create or resolve an agent, attach the capability, set policy, run one real action, then verify the receipt or event on the explorer.
