# Initial HTML

## In short

Initial HTML is the version many agents read, so prices and policies must be in it. Making pages readable goes into the detail. JavaScript rendering and Structured data (JSON-LD) sit beside it in the glossary. Ora's experiment found an answer hidden in JavaScript failed a plain-fetch client on 5 of 5 topics (October 2026).

## Definition
