Amazon SP-API · getMyFeesEstimateForSKU · POST /products/fees/v0/listings/{SellerSKU}/feesEstimate Uses Product Fees v0 API. SKU-based estimates use actual item measurements after the item has been sent to Amazon — more accurate than ASIN-based estimates for FBA sellers. Pass isFba=True for FBA items. Net margin = price − data.totalFeesEstimate.Amount − COGS; never compute it when data.error is set.

Result
Every tool answers {notification, data, human_action}; data carries:
data.sellerSku— the queried SKU.data.price— the price used for estimation.data.isFba— whether FBA or MFN fees were estimated.data.status— 'Success' or error status from Amazon.data.totalFeesEstimate— {Amount, CurrencyCode} — total estimated fees.data.error— null on success; on failure Amazon's {Type, Code, Message} saying WHY there is no estimate, and the Message is in notification.message too. A refused estimate is not zero fees — never write a blank or 0 fee to your sheet when data.error is set, because any margin computed from it is wrong.data.feeDetail— list of per-fee breakdown objects, each with: - FeeType: e.g. 'ReferralFee', 'FBAFees', 'VariableClosingFee' - FeeAmount: {Amount, CurrencyCode} - FinalFee: {Amount, CurrencyCode}
