How this service works
Amazon seller information and storefront. Seller name, ratings, FBA usage and history for up to 100 sellers; optionally the seller's full storefront ASIN list. 1 credit per seller; storefront +9.
Output
A JSON object containing a sellers map keyed by seller ID, each with sellerName, sellerId, and hasFBA (boolean). Also includes _meta fields: cached status, price paid, and marketplace_domain_id. If storefront=1 is requested, the seller's full ASIN list (up to 100,000 ASINs) is included.
Example use cases
Vetting a competitor's Amazon storefront
“I want to research Amazon seller A3P5ROKL5A1OLE on the US marketplace — can you get me their name, ratings, and FBA status, and also pull their full list of ASINs they sell?”
Bulk FBA check for supplier shortlist
“Can you check whether these Amazon sellers use FBA: A1XB2C3D4E5F6G, A7H8I9J0K1L2M3, A4N5O6P7Q8R9S0 — I need their names and FBA status on the US marketplace.”
Checking seller reputation on Amazon UK
“Look up Amazon seller B01234ABCDE on the UK marketplace and tell me their seller name, ratings history, and whether they use FBA.”
Technical details
Endpoint
GEThttps://asin402.com/api/data/seller?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured seller profile data from Amazon — especially FBA status, seller ratings, or a complete product catalog for one or more sellers. Ideal for competitive research, supplier vetting, or marketplace intelligence. Prefer this over product-level endpoints when the subject of interest is the seller entity rather than a specific ASIN. The batch capability (up to 100 sellers per call) makes it efficient for bulk seller screening.
Side effects
- Invalid or non-existent seller ID returns empty or missing seller entry
- Storefront requested for multiple sellers (only one allowed) — returns error
- Unsupported marketplace domain code returns error or defaults to US
- Rate limiting or credit exhaustion returns 402 or error response
- Seller has no ratings history — fields may be empty or null
