Billed on the tokens actually used. Reasoning tokens count as output. Each request adds its exact cost to a running total, and whole credits are taken from your balance when that total reaches 1 credit; the remainder carries over. Failed requests are not charged.
One Fuzion credit balance covers the web app, the API, and MCP. No separate top-up · 1 credit = ฿1
