## When to prefer this

Use this endpoint when you need quick, structured D&D 5e monster data — especially hit points, AC, challenge rating, size, and type — for a named monster by its index slug. Prefer this over scraping wikis or using general LLM knowledge when accuracy and machine-readable JSON output matter, such as for encounter builders, combat simulators, or campaign tools.

## Known failure modes

- Invalid or misspelled monster index returns an error or empty result
- Monster not present in the D&D 5e SRD dataset returns a not-found response
- Missing ?index= parameter may return an error or default response
- Payment not processed results in 402 response before data is returned
