## 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 mission-brief-generator-8d6fe356 -d '<json body>'
```

Example prompt: Generate 3 mission briefs set in a post-apocalyptic wasteland theme — use the seed 'alpha-7' so I can reproduce them later, and factor in that the player has no vehicle access.

## When to prefer this

Choose this endpoint when you need quick, structured mission outlines with explicit goals, constraints, and exit conditions for games, RPGs, or narrative design — especially when reproducibility via seed values or thematic consistency across multiple briefs is required.

## Known failure modes

- Invalid count value outside 1–5 range returns a validation error
- Malformed JSON body results in a 400 Bad Request
- Payment failure or missing x402 payment header causes a 402 Payment Required response
- Extremely vague or empty context may produce generic or low-quality briefs
