Web-grounded answer to any question, as clean JSON: a direct answer plus every factual claim tagged to a source URL and a confidence grade -- an answer an agent can trust and act on, not a search dump. Pass ?q=<your question>.

Delivery + integrity verdict for one x402 endpoint: is it live, does its live price match what it advertises, does it pay to the advertised address, and -- the part nobody else sells -- did it DELIVER when agents actually paid it. Pass ?resource=<endpoint-url>. Every field carries its provenance.
