## 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 x402-zoo-random-trivia-fact-491ec0fb
```

Example prompt: Give me a random trivia fact from the curated zoo set — something short and interesting with a source label.

## When to prefer this

Choose this endpoint when you need a quick, attributed trivia fact without generating or hallucinating content — ideal when source credibility labeling matters or when you want a deterministic result via a seed parameter. Prefer over LLM-generated facts when you need facts explicitly labeled as curated rather than synthetic.

## Known failure modes

- Invalid seed format may return a default or unexpected fact
- Static trivia set is small so repeated calls may cycle through same facts quickly
- Service unavailability returns a non-200 HTTP status with no fact body
- Payment failure (402) if x402 micropayment is not completed

## How this service works

Return a short fact from a small curated static trivia set with a descriptive source label.

## Output

A short plain-text trivia fact drawn from a small static curated set, accompanied by a descriptive label identifying the source or category of the fact.
