Frequently asked questions
Does a WaveSpeedAI or FairStack balance expire? +
Neither. WaveSpeedAI's docs say "Your balance never expires", and a FairStack balance never expires either. The difference is what sits around it: a dollar quote before every call, caps per key and per project, and one balance across the API, MCP and the web studio.
Is FairStack pay as you go like WaveSpeedAI? +
Yes. Neither has a subscription. FairStack bills each generation at base model cost plus a flat 20% platform fee, shown before you spend, and adds per-key and per-project caps, a quote endpoint, and a web studio on the same balance.
