## 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 agentbit-app-ai-summarizer-b32fac81 -d '<json body>'
```

Example prompt: Can you summarize this article in bullet points, keeping it under 150 words? I want the key takeaways with the tone preserved — it's a 3,000-word op-ed on climate policy.

## When to prefer this

Choose this endpoint when you need a semantically rich, LLM-generated summary that captures tone and nuance — not just keyword extraction. Prefer it over the sibling extractive summarizer when the source text contains implicit meaning, sentiment, or rhetorical structure that a sentence-ranking algorithm would miss. Best for articles, reports, meeting notes, research papers, or any prose where comprehension matters. Use the 'bullets' style for scannable output, 'paragraph' for narrative continuity, and 'tweet' for ultra-compact one-liners.

## Known failure modes

- Text exceeds ~40 KB limit — returns an error indicating input is too long
- Invalid style enum value — returns a validation error; must be 'paragraph', 'bullets', or 'tweet'
- max_words exceeds 400 — capped or rejected with an error
- Empty or missing text field — returns a 400 bad request
- Payment failure via x402 protocol — returns 402 before processing

## How this service works

LLM-quality summary of long text as a paragraph, bullets or a one-liner. Reads for meaning (nuance, tone) — unlike the free extractive summarizer.

## Output

A fluent, abstractive summary of the input text in the requested style (paragraph, bullet list, or tweet/one-liner), generated by an LLM to preserve nuance and tone. The word count is guided by the optional max_words soft limit (up to 400 words).
