Understanding Rate Limits

Rate limiting is a crucial strategy for protecting APIs from abuse and ensuring fair usage. Common approaches include:

  • Fixed Window: Simple requests/second limit
  • Sliding Window: Rolling time window for smoother throttling
  • Token Bucket: Allows for burst traffic while maintaining average rates
