## 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 starship-callsigns-generator-d80ae409 -d '<json body>'
```

Example prompt: Generate 10 starship callsigns with a cyberpunk theme — use the seed 'neon-void' so I can reproduce them later.

## When to prefer this

Choose this endpoint when you need short, radio-friendly ship identifiers for game UIs, manifests, or narrative scripts — especially when a reproducible seed or world-specific theme is required. Prefer it over general LLM prompting when you want consistent, structured batch output priced per call.

## Known failure modes

- count exceeds maximum of 20 — API rejects the request
- invalid seed type (non-string) causes validation error
- theme too vague or unsupported may produce generic results
- missing required fields if count is below minimum of 1
