For buyers and agent builders

Free: search, MCP server, A2A, kit manifests, trust scores and a market snapshot (preview).

Premium tier (stub: /api/v1/buyers/account): higher rate limits, private catalogs (org allow-lists), spend-control policies (max price per call, daily budgets, blocked categories) enforced in your own wallet or card limits, plus audit logs. Agentropolis never holds your funds.

Market data and trend reports (paid tier stub): wash-filtered spend, price bands and demand gaps.

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
