## 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 rawgroundbeef-a-cat-fact-04aa3a8f -d '<json body>'
```

Example prompt: Give me a random cat fact.

## When to prefer this

Use this endpoint when you need a quick, single cat fact or trivia statement, especially in x402 micropayment contexts. If you need a picture of a cat instead, use the random-cat-picture endpoint. If you need multiple or truly random rotating facts, consider random-cat-fact sibling endpoint.

## Known failure modes

- Payment failure if USDC balance is insufficient or x402 payment header is missing
- Network timeout if the upstream fact source is unavailable
- Empty or malformed response if the backend data source has an issue
