## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability dialogue-opener-generator-ae1e85c3 -d '<json body>'
```

Example prompt: Generate 3 NPC opening dialogue lines for a suspicious city guard encounter in a dark fantasy setting — the lore is that magic is illegal and the guard has seen the player casting spells nearby. Use seed 'guard42' so I can reproduce the results.

## When to prefer this

Choose this endpoint when you need quick, varied NPC encounter-opening lines for game scenes and want optional lore/theme grounding and reproducibility via seed. It is purpose-built for game narrative workflows and pairs naturally with sibling endpoints like NPC profile generator and dialogue choice seed for a full encounter pipeline.

## Known failure modes

- Invalid count value outside 1–5 range returns a validation error
- Overly vague context may produce generic or off-theme dialogue
- Payment failure via x402 protocol returns 402 status before content is delivered
- Conflicting theme and context inputs may yield inconsistent results
