CRRateLimitTester

Simple Clash Royale Rate Limit Tester Written Using HummingBird and Swift.

Why?

There is no official word on the Clash Royale API's rate limits, so I thought I'd test it myself.

How to test

1- Run the app.
2- Provide your Clash Royale API token as the 'token' environment variable.
3- Call the testing route with a rate and a Clash Royale API endpoint url localhost:8080/test-rate?rate=[rate]&url=[url]

Example

Testing the https://api.clashroyale.com/v1/cards endpoint at 40 requests per second rate:
curl localhost:8080/test-rate?rate=40&url=https://api.clashroyale.com/v1/cards

Results

The rate limit seems to be set at 80.
Testing with rate set at 80 or less will always succeed, and with 81 and above you'll always get the 429 Too Many Requests error.

Bonus

You can test other APIs rate limits as well as long as they use a Bearer token for authorization.
You'll just need to enter the other API's url in the tester route.
