API Rate Limiting & Throttling
Pricing

Token bucket is the most common default: it allows short bursts up to a cap while enforcing a steady average rate, which matches how real clients behave. Fixed-window counters are simplest but let users double their rate at the window boundary; sliding-window log or counter fixes that fairness gap at slightly higher cost. We pick based on how strict your fairness needs are and how much Redis memory you want to spend.
