Intesta

Intesta is a registry of attested fact passports. A business publishes its facts once (delivery, returns, fees, contacts), proves it controls the domain, and AI agents read those facts through MCP/API while visitors see a Verified facts widget. Answers come only from the passport: when a fact is missing, the agent gets an honest refusal instead of a hallucination. Free to register; benchmark and public stats on the site.
