Rate Limiting
Controls how many API requests you can make in a time period to prevent abuse and keep servers stable.
What is Rate Limiting?
Rate limiting caps how many requests you can send to an API within a specific timeframe (like 100 requests per minute).
It protects servers from getting hammered by too many requests at once, whether from bad actors or just enthusiastic builders testing their code.
Most APIs you'll use have rate limits. OpenAI limits requests per minute based on your tier. Stripe has different limits for test vs live mode. You'll see 429 errors when you hit the limit, and your code needs to handle that gracefully with retry logic.
Free tiers typically have stricter limits. Paid plans unlock higher rates. Some APIs like Anthropic's Claude use token-based limits instead of raw request counts.
