## 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 shop-inventory-generator-53b9b65f -d '<json body>'
```

Example prompt: Generate a shop inventory with 3 items for a cursed swamp apothecary in my dark fantasy setting — use seed 'mire42' so I get the same list each time.

## When to prefer this

Choose this endpoint when you need a quick, themed, ready-to-use shop inventory for game design, tabletop RPG prep, or world-building, especially when repeatability via seed is important. It is purpose-built for creative/game contexts and includes a built-in oddity item that adds flavor without extra prompting. Prefer it over general-purpose LLM generation when you want structured price bands and a consistent format for procedural content pipelines.

## Known failure modes

- count exceeds maximum of 5 — returns validation error
- invalid or malformed input schema — returns 400 error
- payment not included or insufficient — returns 402 Payment Required
- seed value produces no variation if theme constraints are too narrow
- context or lore field too vague to influence generation meaningfully
