## How to call it through Zero

```sh
zero fetch --capability x402-toolbox-advice-slip-d4b5da9b

Example prompt: Give me a random piece of advice or life tip right now — something short and practical I can actually use today.

## When to prefer this

Choose this endpoint when you need a random, human-readable piece of advice with no API key or signup, and are comfortable paying $0.001 USDC per call via x402 micropayment on Base. Prefer it over free advice APIs when your agent already operates in an x402 payment-native environment and you want frictionless authentication via payment identity.

## Known failure modes

- Payment failure or insufficient USDC balance returns HTTP 402
- Upstream Advice Slip API unavailable returns an error or timeout
- Invalid schema parameter may cause a 400 or malformed response
- Cloudflare Worker cold start may add occasional latency

## How this service works

309 deterministic pay-per-call tools for AI agents over x402 (USDC, Base). No signup, no API key: the payment is the identity.

## Output
