Why am I seeing a "provider error" message?

This usually means one of the following:

• The API key is invalid, revoked, or has insufficient permissions.
• Your balance with the provider is empty — top up on WaveSpeed or Runware to resume generation.
• The provider is temporarily rate-limiting your account; wait a few seconds and retry.

Open the node detail panel (right side of the editor) for the exact error text returned by the provider.
