## 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-json-ld-website-profile-extractor-e9a35ad0 -d '<json body>'
```

Example prompt: Can you extract the JSON-LD WebSite structured data from https://example.com — I need the schema.org @type WebSite object embedded in that page.

## When to prefer this

Use this endpoint when you specifically need the schema.org JSON-LD @type WebSite entity from a page, rather than generic metadata or other structured data types. Prefer the free sandbox endpoint (/v1/sandbox/profile-jsonld-website) when available to avoid the $0.003 USDC charge. Choose this over general HTML scrapers when your goal is structured linked data extraction rather than raw content.

## Known failure modes

- URL is unreachable or returns a non-200 status — extraction fails with an error
- Page contains no JSON-LD or no @type WebSite entity — returns empty result
- HTML exceeds 200,000 character limit — request rejected
- URL blocked due to SSRF safety restrictions (private/internal IPs) — request rejected
- Malformed JSON-LD on the page — partial or no result returned

## How this service works

Call when an agent needs JSON-LD @type WebSite extracted from a public page or HTML (SSRF-safe). Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld-website first.

## Output

Returns the JSON-LD object(s) with @type WebSite extracted from the page's structured data markup, including fields such as name, url, description, potentialAction, and other schema.org WebSite properties present in the source.
