Get in front of every agent shopping for your category

Full-text search over what machine-payable services actually publish — their descriptions, input schemas, parameter names, prices and settlement networks — across ~18,000 x402 endpoints. Built from their own payment challenges, which a general crawler discards as a dead page: ask for a parameter name, a schema field or a network and you match services whose one-line blurb never mentions it. Filter by price ceiling, by whether the service publishes a call spec, and by payment protocol. Every response states how many documents were searched and how stale the oldest is, because an index that will not tell you its size is asking to be trusted about the one thing you cannot check. Ranked by BM25 — no model, so the same query ranks the same way twice. If the index is empty or nothing matches, you are NOT charged.
