Cost scenario
For $100 of credits bought with the standard purchase fee: $100 × 5.5% = $5.50, above the $0.80 minimum, so the purchase total is $105.50. This is a credit-purchase example, not a same-model inference quote.
KeepBal example: 1,000 successful fixed-price tool calls × the current catalog price per call = usage cost. A live fixed tavily/search price is unavailable in this rendering, so no numeric search quote is shown. Inspect the tool before calling; variable prices need an input-specific quote.
These examples use different billing units unless explicitly matched. KeepBal top-ups are separate from usage: $10 credit + ceil($10 × 8% to cents) + $0.35 = $11.15 before tax. Only $10 enters the wallet. Promotional credit is excluded from the usage arithmetic.
