## 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 text-summarization-with-style-and-word-limit-19664fbb -d '<json body>'
```

Example prompt: Can you summarize this 3,000-word article into bullet points, keeping it under 150 words? [paste article text here]

## When to prefer this

Choose this endpoint when you need structured, style-controlled text summarization with a strict word cap — especially when you need to choose between paragraph prose, a bulleted list, or a TL;DR format. Ideal for agents processing long documents, articles, emails, or contracts where output length must be predictable and controlled. The 24,000-character input limit makes it suitable for large documents.

## Known failure modes

- Text exceeds 24,000 character limit — request rejected
- Invalid style value not in enum (paragraph, bullets, tldr) — validation error
- max_words outside 20-400 range — validation error
- Empty or missing text field — request fails
- Payment not included or insufficient — x402 payment required error
