How this service works
Search live products across online retailers by keyword and price range. Returns product names, prices, retailers, and direct purchase links. Use when an agent needs current shopping options or price-filtered product recommendations.
Output
A list of live product listings matching the keyword and price filter, each including the product name, current price (with currency), retailer name, and a direct purchase URL.
Example use cases
Gift shopping within a budget
“I need to buy a birthday gift — find me options for 'leather wallet' between $30 and $80 USD available in the US, and give me direct links to buy them.”
Finding cheapest laptop deals
“Search for 'gaming laptop' and filter results to anything priced under $1000 in USD for the US market — I want to see prices and retailer names.”
Sourcing products for a specific region
“Can you find 'yoga mat' products priced between $20 and $60 AUD available in Australia, and list the retailers and purchase links?”
Technical details
Endpoint
GEThttps://api.402shelf.com/products/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs real-time, live product listings from multiple online retailers with price filtering — especially when the user wants current prices and direct purchase links rather than historical or cached data. Prefer over general web search when structured product data (price, retailer, buy link) is specifically needed.
Side effects
- No products found for the given keyword or price range — returns empty result set
- Invalid country code or currency code — returns validation error
- Price range minimum exceeds maximum — returns parameter error
- Keyword too vague or too specific — may return zero or irrelevant results
- Service unavailable or payment (x402) not accepted — returns HTTP 402 or 5xx error
