## 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-extract-from-urls-9c7bbf39 -d '<json body>'
```

Example prompt: Extract the text content from all URLs in this block of text: 'Check out the latest findings at https://example.com/report and the summary at https://example.com/summary for more details.'

## When to prefer this

Choose this endpoint when you need to extract readable text from one or more URLs that appear inline within a text block, especially in an agentic pipeline where you receive raw messages or documents containing hyperlinks and need their content without manually fetching each URL. It is particularly useful for autonomous agents that process text from emails, notes, or documents containing links and need to retrieve referenced content cheaply at $0.004 per call via x402 on Base.

## Known failure modes

- URLs in the text are inaccessible or return non-200 responses, resulting in empty or error entries
- Text exceeds 50,000 character limit, causing a validation error
- No valid URLs found in the submitted text, returning empty extraction results
- Target webpage blocks scraping (e.g. bot protection, CAPTCHAs), resulting in partial or no content
- Payment failure via x402 protocol prevents the call from completing

## How this service works

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

## Output
