remove.bg credits
Paste an API key to read its balance. The key is not saved anywhere โ it is sent only to api.remove.bg from this browser, and it disappears when you close the tab.
How the shop uses the key. The wizard tries remove.bg first and falls back to rmb.cardsgoat.com as soon as the key is rejected or the balance hits zero, so the shop never blocks โ it just stops using the paid service.
A heads-up. The key configured in the theme editor is readable in the page source of the personalise wizard, because the call is made from the visitor's browser. Treat it as public and rotate it if it leaks somewhere it shouldn't.
