How this service works
Product search. Send a product query; returns up to 40 Google Shopping offers with title, merchant, price (text plus parsed amount and currency), delivery, rating and link. Use to compare prices or find where a product is sold. Not for stock levels or buying. Prices are as listed at search time and may change. Typical response 1 to 2 s. Failed calls are not charged.
Output
A JSON object containing a list of up to 40 product offers, each with: position, product title, merchant name, price as text and parsed numeric amount, currency code, delivery information, star rating, rating count, product page URL, and optional image URL. Also includes the original query, timestamp of the search, and a data-freshness notice.
Example use cases
Budget laptop price comparison
“Search Google Shopping for 'laptop under $500 16GB RAM' in the US and list all the merchants with their prices and delivery options so I can find the best deal.”
Gift idea sourcing
“Find where I can buy a 'LEGO Technic Bugatti Chiron set' online — search Google Shopping and show me the top offers with prices and ratings.”
Niche product availability check
“Search Google Shopping for 'mechanical keyboard TKL hot-swap RGB' and give me up to 40 results with merchant names, prices, and links so I can see who's selling it.”
Technical details
Endpoint
POSThttps://quantagentshop.com/v1/shopping-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to discover where a product is sold and at what price across multiple merchants, or to power a price comparison feature. It is ideal for finding purchase links, comparing delivery options, and surfacing merchant ratings. Prefer it over news or web search endpoints when the intent is specifically commercial product discovery. Not suitable for checking real-time stock levels, initiating purchases, or monitoring price changes over time.
Side effects
- Empty results if query is too vague or product does not appear in Google Shopping
- Query shorter than 2 characters or longer than 200 characters rejected with validation error
- Invalid country or language code returns an error or falls back to default locale
- Page number outside 1–3 range rejected
- Prices shown may differ from actual merchant prices at time of purchase
- No stock-level information — out-of-stock items may still appear in results
- Service timeout if Google Shopping takes too long to respond
