## 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-offer-extractor-65d20992 -d '<json body>'
```

Example prompt: Can you pull the JSON-LD Offer data from this product page — https://www.example-shop.com/products/blue-widget — I need the price, availability, and currency in structured form.

## When to prefer this

Use this endpoint when you need to reliably extract schema.org Offer structured data from a product or service page, especially when you want SSRF-safe fetching with no risk of hitting internal infrastructure. Prefer the unpaid sandbox endpoint (/v1/sandbox/profile-jsonld-offer) for testing. Choose this over generic HTML scrapers when you specifically need @type Offer JSON-LD and want a structured, typed response rather than raw HTML parsing.

## Known failure modes

- No JSON-LD Offer found on the page — returns empty or null result
- SSRF-blocked URL (private IP ranges, localhost) — rejected before fetch
- URL unreachable or returns non-200 status — fetch error
- HTML too large (>200,000 characters) — rejected at input validation
- Malformed or invalid JSON-LD on the page — parse error returned
- Rate limiting or bot-blocking by the target site — fetch failure

## How this service works

Call when an agent needs JSON-LD @type Offer extracted from a public page or HTML (SSRF-safe). Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/profile-jsonld-offer first.

## Output

Returns the parsed JSON-LD @type Offer object found in the page, containing fields such as price, priceCurrency, availability, validFrom, seller, and other schema.org Offer properties present in the page's structured data markup.
