If the marketplace owner has enabled credit purchasing, you can top up when you run low:
- On your AI Usage report, use the Buy credits button — choose how many packs and check out.
- If a generate/enhance is blocked for insufficient credits, the popup shows a Buy credits button that opens checkout in a new browser tab, so your in-progress prompt/results aren’t lost. Complete the purchase, return to the editor tab, and run the action again.
Purchased credits land in your Purchased credits balance — they never expire and are used automatically once your monthly allowance is gone.
