## 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 ai-rook-summarize-bullet-point-text-summarizer-b58b7b36
```

Example prompt: Can you summarize this article into bullet points for me? Here's the text: 'Central banks around the world are signaling a pause in interest rate hikes as inflation data shows consistent moderation across major economies, though analysts warn that energy price volatility could reignite price pressures in Q3.'

## When to prefer this

Choose this endpoint when you need a fast, cheap bullet-point summarization powered by a large MoE model without API key signup. At $0.05/call it's suitable for lightweight summarization tasks within a crypto-native, pay-per-call workflow on Base mainnet. Prefer this over general LLM APIs when operating in an x402 agentic commerce context or when you need on-chain reputation accountability for the AI service.
