## 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 two-sentence-horror-story-generator-5f324d6e -d '<json body>'
```

Example prompt: Give me a two-sentence technological horror story in English — split it into the setup and the payoff so I can pause between them — and use seed 'midnight-42' so I get the same one if I ask again.

## When to prefer this

Choose this endpoint when you need short-form horror fiction specifically structured for dramatic narration — two sentences split into setup and payoff. It is ideal for storytelling agents, audio narration apps, Halloween content generators, or any scenario requiring deduplication across sessions and reproducibility via seed. Unlike a generic LLM call, it handles story IDs, deduplication, theme filtering, and bilingual output out of the box at a fixed flat rate.

## Known failure modes

- Invalid theme value returns an error or unexpected story
- Unsupported language code falls back to English or errors
- Providing all known IDs in exclude may result in repeated content if the pool is exhausted
- Missing or malformed exclude array in GET format may cause parsing errors
- Seed parameter not preserved correctly leads to non-reproducible results

## How this service works

60 paid endpoints with no metering, no API key and no account. Each endpoint has one flat price per call, whatever the size of the request: LLM completions with automatic failover across several large models, read-only EVM tooling over Base, Ethereum, Polygon, Arbitrum and Optimism, and pure crypto utilities that touch no network.

## Output

Returns a JSON object with a unique story ID (for deduplication), the full joined horror story, the setup sentence alone, the payoff sentence alone, the theme used, the language, and a total count. The split format lets a narrating agent deliver the setup, pause, then land the payoff for dramatic effect.
