Leash identity is all your agent needs to get paid

Understand why a Leash agent identity can hold payment, reputation, capability metadata, and receipts for paid agent services.

Why it matters

Builders often start with a wallet and an API key, but paid agents need a stronger primitive: an identity that can receive, spend, prove, and advertise capabilities.

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.

How Leash handles it

Leash attaches the payment destination, marketplace listing, receipts, and reputation inputs to the agent mint instead of scattering them across unrelated accounts.

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.

Implementation checklist

Mint the agent, attach service endpoints, create payment links under that agent, and list only payable endpoints that belong to the identity you want buyers to trust.

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.

FAQ

Why not just use a wallet address?

A wallet can receive funds, but it does not describe capabilities, policies, receipts, or reputation as an agent identity.

Can one identity sell many services?

Yes. One seller agent can own multiple payable endpoints and marketplace listings.
