How this service works
Fast tools (web read, domain RDAP/DNS/SSL, Federal Register, clinical trials, Polymarket+Kalshi odds, OSV vulnerabilities) and data APIs (leads, jobs, YouTube, Reddit, Trends, tenders...). POST JSON, pay per call in USDC on Base via x402. Charged only when results are returned.
Output
A JSON object with a count and an array of offer items, each containing the product URL, store name, price, and optionally the price converted to the requested currency, sorted from cheapest to most expensive. Only results that matched and had retrievable prices are included.
Example use cases
Best deal on consumer electronics
“Find me the cheapest price for the 'Apple MacBook Air M3' across Amazon, Best Buy, and Newegg — show up to 15 results and only include offers that are in stock, with prices converted to USD.”
Cross-store gift shopping comparison
“I'm looking for the best price on a 'LEGO Technic Bugatti Chiron' — search Amazon, Walmart, Target, and eBay, give me the top 3 results per store sorted cheapest first, and convert all prices to EUR.”
Price check from specific product pages
“Can you pull the actual prices from these three Allbirds product pages and sort them cheapest to most expensive: https://www.allbirds.com/products/mens-tree-runners, https://www.allbirds.com/products/womens-tree-runners, https://www.allbirds.com/products/mens-wool-runners?”
Technical details
Endpoint
POSThttps://2-29-135-242.sslip.io/x402/cheapest-price-finder?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compare real-time prices across multiple e-commerce retailers for a specific product, either by search query or by supplying direct product URLs. It is particularly useful when you want prices normalized to a single currency and sorted by cost. Prefer it over manual web searches when you need structured, machine-readable price data from major retailers like Amazon, Walmart, Best Buy, Target, eBay, and Newegg in a single API call.
Side effects
- No results found if product is not available in specified stores
- Out-of-stock items filtered out if onlyInStock is true, potentially returning empty results
- Invalid store domains may be silently ignored or return zero results
- Currency conversion failures if an unsupported currency code is provided
- Rate limits or scraping blocks from individual retailers may reduce result count
- Payment failure via x402 if insufficient USDC balance on Base
