ASIN redirects and billing
Follow Seller code 9206 means a confirmed product redirect and is billed as a normal request (usually 1 credit; see pointCost). message contains the destination, for example Redirected to ASIN B0DSHTVHNZ. data.json retains the empty result for the original request; the destination product is not queried automatically. Do not automatically retry the original ASIN. Query the destination separately only after confirming it; that request is billed separately. Fetch failures, mismatched delivery destinations, and unconfirmed redirects remain 9200 without a charge.
ASIN not found
When the product-detail check explicitly confirms that the requested ASIN is missing on the current marketplace, Follow Seller returns 9204 with message: ASIN not found on this marketplace: B08HSS37H7 (the requested ASIN). This is billed normally, usually 1 credit; see pointCost. Do not automatically retry the same marketplace and ASIN; check the marketplace and identifier first. The ASIN may still exist on another marketplace. An empty or 404 offers page alone, network failures, challenges, or inconclusive evidence do not establish that the ASIN is missing; unconfirmed results remain 9200 without a charge.
