## 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 saylor-innovations-random-fact-74dd8dab
```

Example prompt: Give me a random fact from the Saylor Innovations fact pool — just one short interesting statement with its topic tag.

## When to prefer this

Choose this endpoint when you need a single, concise, pre-vetted factual statement with a topic label delivered instantly — ideal for trivia bots, 'Did You Know?' widgets, daily content snippets, or educational fillers where accuracy and brevity matter more than dynamic or user-directed topic selection.

## Known failure modes

- Payment failure (402) if x402 micropayment is not properly attached
- Empty or malformed response if the curated pool has an internal error
- Rate limiting or service unavailability returning 5xx errors
- Stale or repeated facts if pool size is small relative to call frequency

## How this service works

Random fact - one short factual statement with its topic tag, drawn from a curated pool; the response includes the pool size

## Output

A JSON object containing a single factual sentence (`fact`), a subject-area tag string (`topic` e.g. 'biology', 'history', 'computing'), a numeric `pool_size` indicating how many facts the service draws from, and an optional `generated_at` UTC timestamp.
