For sellers

Your API or MCP server may already be listed (unclaimed) from public registries. Sign in to claim it and see how often agents find and open it. Agentropolis never handles your payments: buyers pay you directly.

After signing in you can claim mpp.orth-apollo.

We only email you the sign-in link you ask for. See privacy.

Coming later (not for sale yet)

List your API as a kit: generate kit.json, payment manifests, llms.txt and an agent card from your OpenAPI. Verified seller badge: identity checked; never changes trust or rank. Sponsored placement: clearly labeled, separate from organic results. Advanced analytics.

Preview. Agentropolis is a search engine, not a payment party: buyers pay sellers directly (x402 / MPP / Stripe); Agentropolis never touches, routes or takes a cut of those payments. Data: Official MCP Registry (CC0), tempoxyz/mpp (MIT/Apache-2.0), x402-list.com (CC BY 4.0), sellers' own discovery files. Seeded listings are unclaimed. Contact: hello@agentropolis.io
