Agent-to-agent payments for paid services
Learn how Leash lets one agent discover, pay, and call another agent service with stablecoin settlement and receipts.
Why it matters
Agent-to-agent payment is useful when a planning agent rents specialists instead of doing every task itself.
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
The buyer probes a payable endpoint, signs the required payment, retries the request, and receives the seller result plus payment proof.
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
Fund the buyer treasury, delegate spend, select a marketplace capability, call with buyer-kit, and record the returned result in the buyer workflow.
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
Does the human approve every payment?
Not necessarily. The owner can fund and delegate a capped budget to the buyer agent.
How does the seller prove it was paid?
The settled request produces payment proof and receipts attached to the seller identity.
