These days, most companies offer public APIs you can access with a special token generated straight from their dashboard. Similarly, many online projects provide public endpoints to fetch data. The problem? If you send too many requests, you'll hit a rate limiter wall. Discover how to circumvent API rate limiting!


Dive into the world of API rate limit measures—learn what they are, how they work, and the tricks to get around them! 🥷

What's API Rate Limiting?

API rate limiting is a handy technique used by web services to control the number of requests a client can make to their public endpoints within a specified time frame. ⌛


To better understand how this works, imagine you're at a theme park on a sunny Saturday. ☀️ The park offers a refill station for soda cups, but there’s a catch: you can only refill one cup every 10 minutes🥤. Why? To prevent chaos and ensure everyone gets a drink without hogging the fountain.


Now it all makes sense…


That’s exactly how API rate limiting works! 💡


Think of an API rate limit as a speed limit for your data requests—keeping things in check. 🛑 It controls how often users can make requests to a server within a specific timeframe.

Wait… But Why Do Web Services Even Limit Their APIs?

The answer is straightforward: web services limit their APIs to ensure fair usage, prevent abuse, avoid security issues like DDoS attacks, and maintain the overall performance and stability of their services. 🦸‍♂️


That's awesome!


Most companies, social media platforms, and online services provide access to a subset of their data through public endpoints. (Is that really the best way to access their data? 🤔 Not quite! For more insights, check out our article on web scraping vs API).


To access those endpoints, all you need to do is sign up, create an API key, and use it to authenticate yourself against their public endpoints, as detailed in their documentation. 🔑


It's simple!


Sounds easy, right? 😄 Sure, but there are other factors at play, just like API rate limiting! But why is that complex mechanism really necessary? ❓❓❓


Imagine a few users start bombarding the servers with hundreds of thousands of requests per second. The servers would struggle to handle the load, causing slowdowns for all users. Companies definitely want to avoid that, even for free public endpoints! 🚫


No, you can’t!


Users typically aren’t fans of downtime or slow services—especially if they’re paying for access to those APIs 💸. To prevent that, web services implement API rate limit measures to restrict the number of requests a specific user can make within a given timeframe. ⏰


You can usually find these API rate-limiting policies in the provider's documentation. Here are some useful pages for popular web services with public APIs:

What Happens When You Ignore API Rate Limits

For a rate limiter to work, the system needs to count all the incoming requests from a user. But how does it know it’s the same user spamming those requests? 🔍 By keeping an eye on the user’s API key or IP address (or both). That’s how the server can track who’s hitting up the web service!


Now, keep in mind that API rate limit measures vary wildly from provider to provider. Some cap you at X requests per Y seconds with the same API key, while others slap on additional limits for requests from the same IP. There are even services that consider things like endpoint-specific quotas!


Regardless of the implementation, if you hit that limit, expect a “429 Too Many Requests” error response.


The rate limiter when you make too many requests


Basically the server's way of saying, “Whoa there, slow down! Give others a chance too!” 😅


Hitting an API rate limit can range from a simple 429 error to a full-blown IP ban. (⚠️ Pro tip: Follow our guide on how to avoid an IP ban!) And trust me, getting banned is no fun—it can bring your entire automation operation or services relying on those endpoints to a screeching halt. 😱

API Rate Limit Exceeded: What to Do?

How to circumvent API rate limiting? Explore the most effective ways!

Pay More

It’s sad, but like most problems in life, you can just buy your way out of API rate limits 💰. Companies profit by capping requests based on your plan tier. The more you pay, the more requests you can fire off—plain and simple.


But let’s be real… while this isn't exactly the most ethical or infinitely scalable solution, it makes sense from a business perspective. It’s like paying for extra luggage on a flight—you want more room, you gotta cough up more cash. ✈️

Create More API Keys

Some providers track your incoming requests by looking at the API key you use to authenticate. Since each API key has a limit on the number of requests it can produce in a given timeframe, the magic trick here seems obvious: create multiple API keys! 🎩 ✨


What a magic trick!


Paying more for a plan is like scaling vertically, but the idea is to scale horizontally instead—creating multiple keys with different purposes and running them concurrently. Sounds foolproof, right? Well, not so fast…


Providers know that trick and have countermeasures in place:

  • They can link each API key to an account, so the rate limit might count all requests from your account, not just individual keys.

  • They could cap the number of API keys you can create. Want more keys? Pay more!

  • They may also use IP-based rate limiting, preventing multiple keys from bypassing the limit.


So yeah, the game is rigged! 😔

Use Proxies

A proxy server acts like a middleman between you and the web service’s endpoints. It receives your requests, routes them to the target server, grabs the response, and sends it back to you. This way, the web server sees the requests coming from the proxy's IP, not your IP. 🕵️‍♂️


This mechanism lets you cloak your identity behind the proxy’s server. Considering that top-tier proxy providers offer networks of millions of proxy IPs, that's basically unlimited firepower!


That's what you can achieve with proxies


When providers enforce IP-based rate limits, proxies are your go-to solution for bypassing API rate limiting. ⚡


Want to integrate proxies into your OS, browser, HTTP client, or scripts? Piece of cake! 🍰 Just a few clicks or a couple of lines of code, depending on your setup. For more guidance, follow our integration guides.
