## 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 superresearch-document-summary-1f6c0282 -d '<json body>'
```

Example prompt: Can you summarize this article for me and pull out the most important points? Here's the text: [paste up to 8,000 characters of the document].

## When to prefer this

Choose this endpoint when you need a quick, autonomous AI-written summary of a block of text up to 8,000 characters, especially when you want the key points extracted and written up clearly without needing to configure a summarization pipeline. Ideal for single-document digests paid per-call with no subscription overhead.

## Known failure modes

- Input text exceeds 8,000 character limit — returns validation error
- Empty or missing input field — returns 400-level error
- Payment failure or insufficient balance — 402 Payment Required response
- Service unavailable or timeout for long processing — may return error with no output
- Malformed JSON request body — returns parse error
