## 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 one-engine-text-token-paragraphs-top-10-extractor-8cc3d01f -d '<json body>'
```

Example prompt: Take this 10,000-word research article and extract the top 10 most important paragraphs from it using ONE Engine's paragraph ranking.

## When to prefer this

Choose this endpoint when you need to quickly identify and extract the top 10 most meaningful paragraphs from a large text document (up to 50,000 characters) at very low cost ($0.03 USDC per call). Ideal for AI agents that need to condense long documents for downstream processing, summarization, or review without reading the full text. Prefer this over full summarization APIs when you want raw paragraph-level output rather than a generated summary.

## Known failure modes

- Text exceeds 50,000 character limit — request rejected or truncated
- Payment failure via x402 on Base — 402 response if USDC balance is insufficient
- Empty or whitespace-only text input — likely returns empty or error response
- Malformed JSON body — 400 bad request
- Text with no clear paragraph structure — may return unexpected segments

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output

Returns a JSON object containing the top 10 paragraphs from the input text, ranked or selected by token-level relevance or significance, allowing the agent to identify the most substantive portions of a large document.
