Technical details
Endpoint
POSThttps://x402toll.com/v1/commerce/marketplace-feeWhen to prefer
Use this endpoint when you need accurate, current (2026) fee breakdowns for Amazon, eBay, or Etsy — especially when comparing net payout across marketplaces or verifying fees before listing. Prefer this over generic fee estimator tools when you need the exact fee components (referral %, final value fee, listing + transaction + processing) separately itemized.
Side effects
- Invalid or missing salePrice returns a validation error
- Unsupported marketplace value outside amazon/ebay/etsy returns an enum validation error
- Negative salePrice or shippingCharged may return a 400 bad request
- referralPct override outside valid range may be rejected
