## 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-urls-t5-f90e60f9 -d '<json body>'
```

Example prompt: Can you pull out all the URLs from this text for me? Here's the content: 'Check out our blog at https://example.com/blog and our docs at https://docs.example.com — also mentioned in the thread was http://forum.example.org/post/123.'

## When to prefer this

Choose this endpoint when you need a cheap, fast, pay-per-call URL extraction from raw text without setting up a heavier NLP pipeline. Ideal for autonomous agents that encounter blobs of text and need to enumerate all embedded links programmatically. At $0.0025 USDC per call via x402 on Base, it's cost-effective for high-frequency agent workflows. Prefer this over regex-based self-implementation when reliability and structured output matter.

## Known failure modes

- Input text exceeds 50,000 character limit — request rejected
- No URLs found in text — returns empty list
- Malformed or non-HTTP URLs may not be detected
- Payment failure via x402 — 402 response returned before processing
- Ambiguous or partial URLs (e.g. www.example.com without scheme) may be missed or inconsistently included

## How this service works

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

## Output
