## 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-faq-json-ld-extractor-7474c1b7 -d '<json body>'
```

Example prompt: Can you extract the FAQ JSON-LD structured data from https://example.com/help — I need all the FAQPage schema.org markup from that page.

## When to prefer this

Choose this endpoint when you need to programmatically extract schema.org FAQPage JSON-LD structured data from a live public URL or raw HTML. It is SSRF-safe, making it suitable for agent workflows that fetch third-party pages. Prefer the free sandbox endpoint (/v1/sandbox/profile-jsonld-faq) for testing before committing to the $0.006 USDC paid call.

## Known failure modes

- URL is not publicly accessible or returns a non-200 status — extraction fails
- No JSON-LD FAQPage markup present on the page — returns empty or null result
- HTML exceeds the 200,000 character limit — request rejected
- URL blocked by SSRF safety checks — request rejected
- Malformed HTML prevents parsing — partial or empty result returned

## How this service works

Call when an agent needs JSON-LD @type FAQPage extracted from a public page or HTML (SSRF-safe). Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld-faq first.

## Output

Returns the parsed JSON-LD @type FAQPage object extracted from the page or HTML, including all question-answer pairs structured according to the schema.org FAQPage specification.
