## When to prefer this

Use this endpoint when an AI agent or user needs to look up official D&D 5e rules text by topic keyword — e.g. combat, conditions, spellcasting, resting — and wants structured JSON results from the Open5e reference. Prefer this over general web search when you need structured, machine-readable rules data specifically from the 5e SRD.

## Known failure modes

- Empty result set if the keyword matches no rules sections
- HTTP 402 if payment header is missing or invalid
- Malformed or missing query parameter returns error or empty results
- Rate limiting or service unavailability returns 4xx/5xx error
