How this service works
Amazon Product Finder: filter the whole catalog by 300+ criteria. Find ASINs matching any combination of 300+ filters: price ranges, sales rank, monthly sales, offer counts, buy box share, Amazon presence, brand, category, rating, dimensions, price drops, out-of-stock rates and more. Pass the Product Finder query as JSON in 'selection' (GET) or as the JSON body (POST). Returns ASINs; fetch details with /api/data/product. 10 credits + 1 credit per 100 results; stats=1 adds 30 credits.
Output
A JSON object containing an array of ASINs (asinList) matching the filter criteria, a totalResults count, and metadata including whether the response was cached, the price paid, and the marketplace domain ID. If stats=1 was requested, aggregate statistics across all matching products are also included.
Example use cases
Private label opportunity scouting
“Find me Amazon products in the US marketplace with monthly sales between 5,000 and 15,000, fewer than 10 sellers, no Amazon presence on the listing, and at least a 4-star rating — I want to spot low-competition niches worth entering.”
Retail arbitrage product sourcing
“Give me a list of Amazon ASINs where the buy box price just dropped, there are fewer than 5 offers, and the sales rank is in the top 2% of their category — sort by price drop size descending.”
FBA catalog filtering by size and price
“Search the Amazon UK catalog for products priced between £15 and £50 that are small and light (under 1 lb), have a buy box share above 80%, and are selling at least 500 units a month — also include the aggregate stats for all matches.”
Technical details
Endpoint
GEThttps://asin402.com/api/data/finder?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to bulk-discover Amazon ASINs matching a precise multi-criteria filter — especially for product research, arbitrage sourcing, or niche analysis. It excels over keyword search when you want numeric criteria (price, sales rank, offer count, buy box share) rather than relevance ranking. Prefer it over scraping or keyword endpoints when you need structured, filterable catalog access across 300+ dimensions.
Side effects
- Invalid or malformed selection JSON returns a 400 error
- Unknown filter field names in selection query cause rejection
- Insufficient credits returns a payment/quota error
- Specifying an unsupported marketplace domain code returns an error
- Very broad queries with millions of results may time out or require pagination
- Stats flag adds 30 credits; unexpected credit depletion if not accounted for
