Can my unused Catalyst credits be extended, or reinstated after they expire?

No. One-time Catalyst credits, such as the USD 250 credit, are valid for a limited period, and unused credit expires at the end of it. Expired credits can’t be extended or reinstated. After they expire, your usage is billed under the pricing model you selected, and on pay-as-you-go the monthly free tier still applies.

To get the most from the credit:

1. Claim it when you are ready to build rather than while you are still evaluating. You can claim it at any time from Get $250 Credits in the console.
2. Check the balance in Settings → Billing → Manage Billing → Credits Info.
3. Watch your usage in Settings → Billing → Overview.

Note: The credit is a one-time benefit and is not refreshed monthly like the free tier.
