## 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 npc-profile-generator-c6be35b9 -d '<json body>'
```

Example prompt: Generate 3 NPC profiles for a dark fantasy setting with established lore that the thieves guild controls the city — include their roles, motives, secrets, and voice cues, and use seed 'thieves-city-01' so I can reproduce them later.

## When to prefer this

Choose this endpoint when you need quickly usable, structured NPC character sketches for tabletop or video game contexts — especially when you want each character to have a role, motive, secret, and distinct voice cue in a single compact payload. Prefer it over manual writing when you need to rapidly populate a world or when repeatable seeded results are important for consistency across sessions.

## Known failure modes

- count out of range (must be 1–5) returns a validation error
- malformed JSON body returns a 400 error
- seed collision may produce identical profiles when used with the same parameters
- overly vague context may yield generic profiles that don't fit the intended setting
- payment failure via x402 protocol returns a 402 Payment Required response

## How this service works

NPC profile generator: Generate compact NPC profiles with a role, motive, secret, and voice cue.

## Output

Returns one or more compact NPC profiles (up to 5), each containing a role (the NPC's function or occupation), a motive (what drives them), a secret (a hidden fact about them), and a voice cue (a distinctive speech pattern or phrase) suitable for immediate use in a game or narrative.
