Use our API Rate Limit & Token Bucket Capacity Calculator to define optimal throttling parameters for your APIs. Prevent abuse, manage traffic, and ensure fair resource distribution by calculating burst limits, refill rates, and total bucket size efficiently.
Formula:
Understanding the core principles helps in optimizing your API. Here are the key formulas this calculator uses:
- Effective Requests per Second = Refill Rate / Request Cost
This determines the sustained rate at which requests can be processed. - Maximum Burst Requests = Burst Limit / Request Cost
This indicates how many requests can be served immediately when the bucket is full. - Token Bucket Capacity (Max Tokens) = Burst Limit
The maximum number of tokens the bucket can hold, representing its total capacity.
Where:
Refill Rate: Tokens added to the bucket per second.
Burst Limit: Maximum tokens the bucket can accumulate.
Request Cost: Tokens consumed per single API request.
