Agentropolis

Search the Agentropolis index of 41,806 agent-usable listings (MCP servers, x402/MPP pay-per-call HTTP APIs, A2A agents and kits) by task keywords, with optional filters. Use it first when you need a tool for a task; then use get_kit for one listing's trust evidence and price, or get_kit_manifest for how to call it. Not for browsing categories (list_categories) or market totals (get_market_snapsho

Get the full Agentropolis record for one listing by id: summary, pricing, payment-verified trust evidence (verified buyers, settlements, wash flags, disclosed test sales), badge tiers, sources and links. Use it after search_kits to judge whether a listing is worth using; use get_kit_manifest instead when you need the machine-readable invoke contract (endpoints, schemas, payment offers). Read-only,

Get the kit.json v0.1 manifest for one listing: how to call it (HTTP, MCP or A2A endpoints), input/output schema references, payment offers (rail, network, asset, payTo, amount), discovery files and a trust summary. Use it when you are about to call a listing yourself; use get_kit for human-readable details and trust evidence, or call_kit to call an x402 listing through Agentropolis. Read-only, no

Send a request to a listing's x402 endpoint through Agentropolis and get the seller's raw response back (status, headers, body). Use it only for listings whose search result has buy='relay_x402' (links.call present); for any other listing, call the seller directly using get_kit_manifest. Flow: call without payment, receive HTTP 402 with the seller's payment requirements unchanged, sign a payment w

List every category in the Agentropolis index with its listing count, largest first (about 18 snake_case ids such as web_search, crypto_onchain_data, llm_inference). Use it to pick a valid value for search_kits' category filter or to see what the index covers; for paid-usage numbers per category use get_market_snapshot. Read-only, no parameters. Category pages with prices and verified buyers: /cat

List the registries and directories Agentropolis ingests or deliberately excludes, with each source's license or terms decision, robots handling and listing count (e.g. Official MCP Registry CC0, x402-list.com CC BY 4.0; Coinbase Bazaar link-out only). Use it to check provenance or the attribution required before citing results; it does not search listings (use search_kits). Read-only, no paramete

Explain how Agentropolis computes trust scores (method hub-trust-v0.1) and ranks search results: which payment evidence counts, wash-trading exclusions, low-sample caps, why our own test purchases never count, and what a null score means. Use it to interpret the trust and badge fields from search_kits or get_kit; it returns the method, not any listing's score. Read-only, no parameters.

Build a URL that searches Coinbase's x402 Bazaar (Agentic.Market) for a query. Use it when you want x402 services that may be missing from the Agentropolis index; it only returns a link for you or your user to open. Agentropolis makes no request to Coinbase and does not cache or republish Bazaar data (their terms forbid it). Read-only. Example: {"q":"web search"}.

Get 30-day x402 paid-usage statistics per category, with wash trading filtered out: services with paid usage, verified buyers, settlements, median listed price and listings excluded for wash signals. Use it for market sizing or price benchmarking; to find individual tools use search_kits. Read-only, no parameters. Data: x402-list.com measured settlements (CC BY 4.0, attribute when quoting) plus Ag

List Agentropolis platform features with status (live, partial, stub, planned), endpoint and guardrails: badges, the x402 relay, seller claims and analytics, sponsored placement, market data, billing. Use it to check whether a platform capability exists before relying on it; it describes Agentropolis itself, not listings. Read-only, no parameters. Stub endpoints answer HTTP 501; payments_enabled s
