This Script Won't Work Due to Cloudflare Rate Limiting (Working Code Included)

[MatchaOnMuffins]

Describe the bug Discord protects its services with the Cloudflare network, which imposes strict API rate limiting. The original Gift Code validity checker quickChecker (which relies on spamming the API) will get blocked after roughly 5 requests. The Discord Gift Code API rate limit is roughly 5 requests per minute. This is a fundamental issue (aside from the minuscule chance of getting a valid code by brute-forcing).

• OS: ANY

Smartphone:

Additional context

Rate limits exist across Discord's APIs to prevent spam, abuse, and service overload. Limits are applied to individual bots and users both on a per-route basis and globally. Individuals are determined using a request's authentication—for example, a bot token for a bot. -- Discord API Documentation

Exceeding A Rate Limit In the case that a rate limit is exceeded, the API will return a HTTP 429 response code with a JSON body. Your application should rely on the Retry-After header or retry_after field to determine when to retry the request. -- Discord API Documentation

Working Code

The following is an improved version of the original code, where rate limits are handled by default and the possibility of generating legit Nitro Gift Codes actually exist. However, the chances of getting a valid Nitro Gift Code using any brute-forcing method is roughly $3.12 \times 10^ {-30}$ (if around 10000 Nitro Gift Codes are in circulation at any given moment), so the possibility of obtaining Nitro this way is possibly 28 orders of magnitudes smaller than simply asking a parental figure to purchase it for you and 21 orders of magnitudes smaller than winning the world's biggest lottery.

Other Issues

The URL provided to quickChecker in main is an address instead of a Gift Code, which will result in a response status code of 404 not found regardless of the Gift Code. changing url to code in line 120 will fix this. This issue is fixed in the code above. https://github.com/logicguy1/Discord-Nitro-Generator-and-Checker/blob/63d7070234bb2af94ba3caa1db615b1ad83b548e/main.py#L118-L120

@MatchaOnMuffins bro, can you write a code where the nitro check will be without a webhook? And so that the logs are also displayed

@MatchaOnMuffins bro, can you write a code where the nitro check will be without a webhook? And so that the logs are also displayed Just set "Use_WebHook" to False

[Yu-Vitaqua-fer-Chronos]

Is there any way to make it faster? Doubt it since ratelimiting but, would be nice

[Yu-Vitaqua-fer-Chronos]

One solution could be proxy servers, perhaps?

[MatchaOnMuffins]

Yes, proxy servers would work, but it would still take forever to generate a working code

[logicguy1]

You need private proxies for that, might as well just buy nitro
