## 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-clean-joke-27b5986a
```

Example prompt: Tell me a random clean joke — something family-friendly with the setup and punchline separated.

## When to prefer this

Choose this endpoint when you need a pre-curated, family-friendly joke with setup and punchline delivered as structured separate fields rather than a single string. It is ideal for agents building kid-safe, workplace-appropriate, or all-ages experiences where content moderation matters and you want a fast, cheap ($0.01 USDC) single-call response. Prefer it over open joke APIs when you require a guaranteed clean rating field and structured JSON output.

## Known failure modes

- Network or server error returning a non-200 status with no joke payload
- Payment failure or x402 authentication rejection blocking the response
- Null or missing generated_at field if timestamp generation is unavailable
- Occasionally repeated jokes due to random selection from a finite pool

## How this service works

Random clean joke - setup and punchline as separate fields, drawn from a curated family-friendly pool with a rating field

## Output

A JSON object containing: setup (the lead-in line or question), punchline (the payoff), rating (always 'clean'), pool_size (total number of jokes in the service's curated pool), and generated_at (UTC timestamp of the response, may be null).
