## 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 syntexa-agentshelf-profile-json-ld-review-extractor-f0b058e7 -d '<json body>'
```

Example prompt: Can you pull out any JSON-LD Review structured data from this product page — https://www.example.com/product/widget-pro — and give me the rating, reviewer name, and review body?

## When to prefer this

Choose this endpoint when you need to reliably extract @type Review JSON-LD structured data from a public webpage or already-fetched HTML, and you want an SSRF-safe, paid-per-call service. Prefer the free sandbox variant (/v1/sandbox/profile-jsonld-review) first; use this paid endpoint when the sandbox is unavailable or rate-limited. Best suited for pipelines that need structured schema.org Review metadata rather than raw review text scraping.

## Known failure modes

- URL is inaccessible or returns a non-200 status — extraction fails with error
- No JSON-LD Review objects found on the page — returns empty result or error
- HTML input exceeds 200,000 character limit — request rejected
- SSRF-blocked URL (internal/private IP range) — request denied for security
- Malformed or non-JSON-LD structured data on page — parsing error returned
- URL schema is invalid or under 8 characters — validation error

## How this service works

Call when an agent needs JSON-LD @type Review extracted from a public page or HTML (SSRF-safe). Exact $0.007 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld-review first.

## Output

Returns extracted JSON-LD objects of @type Review found in the given URL or HTML, including fields such as reviewRating, author, reviewBody, datePublished, and itemReviewed, structured as machine-readable JSON-LD.
