## 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`):

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) AI-generated summary of a text passage and are already operating within an x402 payment-capable agent framework. Suitable for single document or passage summarization; prefer this over full LLM API calls when cost and simplicity matter.

## Known failure modes

- Empty or missing input text returns an error
- Input text that is already very short may return unchanged or near-identical output
- Extremely long inputs may be truncated or rejected due to token/size limits
- Non-text or binary content will fail
- Network timeout for very large inputs

## Output

Returns a shortened, coherent summary of the input text, capturing the main points and key ideas in a condensed form.
