Example prompt: Can you generate 3 shopkeeper NPC dialogue lines for greeting, refusal, and rare stock in a gritty steampunk setting? Use the seed 'ironvault' and keep the tone gruff and suspicious.

## When to prefer this

Choose this endpoint when you need quick, reproducible transactional NPC shopkeeper dialogue — particularly greeting, refusal, and rare-stock lines — for game development, tabletop prep, or narrative design. It is especially useful when you want themed output tied to a specific world or lore, or when repeatability via a seed string matters.

## Known failure modes

- Invalid count outside range 1–5 returns a validation error
- Conflicting theme and context inputs may produce inconsistent dialogue tone
- Missing required fields may result in generic, unthemed output
- API payment failure (402) if USDC payment is not processed correctly
