## 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 shelf-thirdmade-net-text-summarizer-0517fe50
```

Example prompt: Can you summarize this article and pull out the top keywords? Here's the text: 'Artificial intelligence is transforming industries worldwide. Companies are investing billions in machine learning research. The technology is reshaping how we work, communicate, and solve complex problems.'

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.001 USDC) extractive summary with keyword extraction in a single call. Ideal for text triage, content tagging, SEO analysis, or any workflow where you need to quickly understand large volumes of text without sending it to a heavier LLM. Best for plain text input where extractive (verbatim sentence) summaries are acceptable.

## Known failure modes

- Missing 'text' query parameter returns an error
- Empty or very short text may produce poor-quality summaries or fewer than 5 keywords
- Extremely long texts may be truncated or exceed processing limits
- Non-English text may yield degraded keyword and summary quality
- Payment failure (x402) results in 402 response and no output

## How this service works

Extractive summary (3 sentences) + top-5 keywords from any text.

## Output

Returns a 3-sentence extractive summary of the input text (sentences drawn directly from the source, not paraphrased) along with a list of the top 5 keywords or key phrases that best represent the content.
