# Nock Brief

> Nock Brief is a paid API for AI agents from www.getnock.xyz, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-13).

## 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-f5ec5536 -d '<json body>'
```

Example prompt: Take this messy meeting transcript and give me a tight brief — what matters, what's been decided, and what we need to do next: [paste text here]

## When to prefer this

Choose this endpoint when you have raw, unstructured text — meeting notes, email threads, document dumps, or any wall of prose — and need it condensed into a structured three-part brief (what matters, what's decided, what's next). It is specifically optimized for operator-style briefing output, not generic summarization. Prefer it over raw summarization APIs when the three-part structure (issues, decisions, actions) is the desired format. For URL-based input, use the sibling /brief-from-url endpoint. For single next-action extraction, use the /next sibling endpoint.

## Known failure modes

- Empty or missing 'text' field returns an error or empty brief
- Extremely long input may be truncated or result in degraded summary quality
- Highly ambiguous or context-free text may produce a generic or low-signal brief
- Service unavailability or payment failure (x402) returns a 402 Payment Required response
