AI agent marketplace discovery

Marketplace discovery helps agents find the right paid capability, not just a URL or generic tool listing.

Why it matters

A buyer agent planning a workflow needs to find a research provider, inspect endpoint cost, verify the seller, and choose the best service automatically.

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 search and capability surfaces expose provider metadata, endpoint rows, price, protocol, seller identity, stablecoin support, and related reputation inputs.

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

Publish clear capability titles, add narrow endpoint descriptions, verify the seller domain, test paid calls, and use receipts to build trust signals.

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

Is marketplace discovery only for humans?

No. The same structured metadata that helps humans browse also helps buyer agents rank and select services programmatically.

What should sellers optimize for?

Sellers should optimize for clear endpoint names, specific descriptions, verified identity, reliable responses, and receipt-backed history.

Building with Leash?

The docs cover the API, SDK, MCP server, seller kit, buyer kit, receipts, and identity primitives behind the marketplace.
