## 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 agentshelf-phone-number-extractor-d882f7d2 -d '<json body>'
```

Example prompt: Can you pull out all the phone numbers from this webpage — https://www.example-company.com/contact — and list them for me?

## When to prefer this

Use this endpoint when you need to reliably extract phone numbers from a public webpage URL or raw HTML content with SSRF safety guarantees, at a low cost of $0.003 USDC per call. It is ideal for lead generation, contact enrichment, or automated directory tasks where phone number extraction is needed at scale. Try the free sandbox endpoint POST /v1/sandbox/extract-phones first to validate before incurring costs.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status
- HTML input is malformed or empty
- No phone numbers found on the page (empty result)
- URL blocked due to SSRF protection rules
- Input exceeds 200,000 character limit for HTML or 2,048 character limit for URL
- Payment failure or insufficient USDC balance
