## 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 nock-brief-generator-3a8b7bef -d '<json body>'
```

Example prompt: Can you boil down this project update into a Nock brief — I need to know what matters, what's been decided, and what's coming next: 'We finalized the v2 launch date for July 1st. The team agreed on a $50k marketing budget. We still need to hire a designer and confirm the hosting vendor.'

## When to prefer this

Choose this endpoint when you need a fast, structured three-part brief (matters / decided / next) from freeform text and want a lightweight, pay-per-call model at $0.05 USDC. It is well-suited for agents that process documents, meeting notes, or status updates and need a consistently formatted output without standing up their own summarization pipeline.

## Known failure modes

- Missing or empty 'text' field returns an error or empty brief
- Extremely short input may produce sparse or low-quality brief sections
- Very long input text may be truncated or exceed processing limits
- Ambiguous source text with no clear decisions or next steps may produce generic output
- Network or payment failures via x402 protocol result in 402 Payment Required before processing begins
