The whole fee schedule

Public, versioned, machine-readable. This table and the API serve the same document — what you see here is what the ledger charges.

Seller FAQ

When do I get paid?

Sales clear 7 days after delivery (the buyer dispute window), then the balance is withdrawable. Request a payout any time above €20.00 — SEPA or PayPal, processed within 5 business days, no payout fee.

What documents do I need to apply?

A company registration extract or business license (PDF or photo, up to 900 KB per file), plus basic company and contact details. Reviews normally complete within 24–72 hours.

What can I sell?

Game keys, game top-ups and gift cards. You tell us what you supply and where your stock comes from in the application — publisher and distributor sourcing is what we vet hardest.

Which currencies are supported?

Supplier pricing and payouts are EUR-only in v1. Buyers may see converted display prices, but your offers, ledger and payouts are always in EUR.

Do I need the API to sell?

No — you can upload keys and manage offers entirely in the portal. The API (with declared stock, webhooks and a sandbox) is there when you want to automate.
