## 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-t4-8896918a -d '<json body>'
```

Example prompt: Extract the text content from these URLs for me: https://example.com/article1 and https://example.com/article2 — I need the readable text from each page so I can summarize them.

## When to prefer this

Choose this endpoint when you need low-cost, pay-per-call text extraction from URLs embedded in a text string, especially in autonomous agent workflows using x402 micropayments on Base. At $0.0015 USDC per call it is economical for high-volume extraction tasks. Prefer it when your agent already has a text blob containing URLs and needs to batch-retrieve their textual content without managing a full browser or crawler infrastructure.

## Known failure modes

- URL is inaccessible or returns a non-200 status — extraction may fail or return empty results
- Text payload exceeds 50,000 character limit — request rejected
- No valid URLs found in text — may return empty or error response
- Target page uses heavy JavaScript rendering — static extraction may miss dynamic content
- Rate limiting or bot protection on target sites — extraction blocked
- Malformed URLs in text — parsing errors

## How this service works

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