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.
Example use cases
Product price extraction for comparison
“Grab the structured offer data from this Amazon listing — https://www.amazon.com/dp/B08XYZ1234 — I want to see the price, currency, and availability as a JSON-LD Offer.”
E-commerce data pipeline enrichment
“I have the HTML of a product page from our supplier's site, can you extract the JSON-LD Offer block from it so I can get the price and stock status without having to parse the whole page myself?”
Monitoring competitor pricing
“Fetch the JSON-LD Offer from https://competitor-store.com/products/fancy-gadget and tell me what price and availability they're currently advertising.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/profile-jsonld-offer?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
