USD per clip or per image. RelaySwitch: live from the media catalog. kie.ai: https://kie.ai/veo-3-1 and https://kie.ai/nano-banana-pro, read 2026-10-19, its credit prices at the dollar figure printed beside them. Google: its Gemini API list as the catalog records it.
02The billing rules that decide it
- Both are prepaid. kie.ai sells credits (a $1,250 top-up adds 10% bonus credits, per its FAQ on 2026-10-19); here the balance is USD from a small first top-up, no subscription.
- Here every generation shows its price before it runs, and a failed generation is not charged.
- Here you pay by card (including Apple Pay and PayPal) or crypto (USDT, USDC, BTC, ETH, SOL), with no identity documents.
- One key covers media and text: the chat models and the media models bill from the same balance.
