A 429 Too Many Requests error means you have sent too many requests to a server in a given time period. The server is rate limiting you to protect itself from overload or abuse. This is a deliberate server response, not a bug. The server knows exactly what it is doing: it is telling you to slow down.
Rate limiting is standard practice on APIs, login pages, search endpoints, and high-traffic websites. The 429 status code includes a “Retry-After” header telling you how long to wait before trying again.
How to Fix 429 as a Visitor
Wait before retrying. The server is asking you to slow down. Wait 30-60 seconds, then try again. Do not spam the refresh button as this extends the rate limit. Clear your browser cache if the error persists after waiting, as a cached rate limit response may be served even after the cooldown expires.
How to Fix 429 as a Developer
Implement exponential backoff in your code: when you receive 429, wait 1 second, then 2, then 4, then 8 seconds between retries. Read the “Retry-After” response header for the exact wait time. Cache API responses to reduce request frequency. Use API pagination to fetch data in smaller batches. Respect rate limit headers that many APIs return (X-RateLimit-Remaining, X-RateLimit-Reset).
Frequently Asked Questions
Why am I being rate limited?
Common triggers: refreshing a page too rapidly, automated scripts making many requests, browser extensions that make background API calls, multiple tabs open to the same site, and shared IP addresses (office, VPN) where multiple users’ requests count against one limit.
Does changing IP address bypass rate limiting?
Sometimes. If the rate limit is IP-based, switching to mobile data or using a VPN gives you a fresh IP. However, many servers also rate limit by user account, session token, or API key, so changing IP alone may not help if you are authenticated.
How long does a 429 rate limit last?
It varies by server. Common durations are 60 seconds for light rate limiting, 15-30 minutes for repeated violations, and up to 24 hours for severe abuse. Check the Retry-After header in the response for the exact duration specific to your situation.
