## 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-content-summarizer-4271ed8e -d '<json body>'
```

Example prompt: Can you summarize the following article into 5 sentences? [paste of a 2,000-word news article about renewable energy policy]

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call text summarization with no API key setup — ideal for agent pipelines that process variable volumes of text and need concise digests of articles, documents, contracts, or scraped web content. Particularly useful when you need to control the exact number of output sentences. Prefer this over heavier LLM calls when the sole goal is summarization and cost-per-call predictability matters.

## Known failure modes

- Text exceeds 100k character limit — request rejected or truncated
- Sentences parameter out of range (less than 1 or greater than 20) — validation error
- Empty or whitespace-only text input — may return empty summary or error
- Payment failure via x402 — 402 response, no summary returned
- Extremely short input text that cannot meaningfully fill the requested sentence count — output may be shorter than requested

## How this service works

Extractive summary of any text, computed offline (no LLM): ranks sentences by term significance and returns the top ones in reading order. Set how many sentences you want. Key-less, instant, $0.002.

## Output

A JSON object containing a condensed summary of the provided text, expressed as the requested number of sentences (1–20, defaulting to 3). The summary captures the main points of the input in natural language.
