This is the server-side balance check: your AI Wallet holds less than $0.07, which is the minimum any text generation costs (image generation and receipt scans check the same threshold). Buy credits on Marketing > AI Tools > Buy AI Credits – the balance updates instantly – or switch on Auto Recharge so the wallet refills itself. If Auto Recharge is on and you still see this, the card charge failed; update the card on file with Sprwt.
