Use this endpoint when you need the complete, verbatim rules text for a specific D&D 5th Edition rule section identified by its slug index. Prefer this over general web search when you want structured, machine-readable JSON of official rules content for use in game tools, chatbots, or character assistants.

## Known failure modes

- Invalid or unknown index slug returns an error or empty result
- Missing ?index= parameter may return a 400 or default error
- Typo in index slug (e.g. 'ability-check' vs 'ability-checks') yields no match
- Non-existent rule sections return 404 or empty JSON
