HTTP 402 Email address must be confirmed before paid resources can be created

What happened

The account that owns the project has not confirmed its email address, and paid resources are not created until it does. This is checked before the payment card, so it can appear even when a card is already linked.

What to do

Confirm the address using the message sent at sign-up, or request a new message in the Client Area. Then send the same request again with a NEW Idempotency-Key: reusing the earlier key replays the stored refusal for up to 24 hours instead of trying again.

Retrying

Change the state this refers to, then repeat the same request with the same idempotency key.
