## 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 crypto-shark-fleet-ai-worker-341705fb -d '<json body>'
```

Example prompt: Run this text through the Crypto Shark Fleet AI worker and give me the result: 'Summarize the key risks in the following DeFi protocol whitepaper: [whitepaper text]' — pay the $0.08 USDC fee on Base.

## When to prefer this

Choose this endpoint when you need a pay-per-call AI text generation worker billed directly in USDC on Base mainnet via the x402 protocol, and want to avoid subscription-based API keys. Ideal for autonomous agents that need to call AI capabilities on demand with crypto-native micropayments. Best suited for text inputs up to 14,000 characters where a GPT-class model response is sufficient.

## Known failure modes

- Insufficient USDC balance or failed x402 payment — payment rejected before processing
- Input exceeds 14,000 character limit — request rejected with validation error
- Model unavailability or upstream API failure — 500 error with no result
- Malformed input JSON — missing or invalid 'input' field returns a schema error
- Network or DNS instability on duckdns.org domain — connection timeout or unreachable host
