Plans give you a monthly credit allotment. Every routed model call costs a fixed number of credits. Basic $5 / 400 · Starter $19 / 2,500 · Pro $49 / 6,500 · Business is custom-priced. Every plan can use every model and every connector. There is no free plan — an account without a subscription has 0 credits.
Credits are deducted only for successful tasks. Failed calls cost you nothing. Unused credits roll over up to your plan's rollover cap (Basic 100, Starter 500, Pro 1,500; Business is set per agreement).
The pre-flight credit estimate shown before each command is a fair upper-bound — real cost is metered from actual token / character / duration usage and is almost always lower than the quote. You will never be charged more than the quoted amount.
