Using similar endpoints

If you are attacking the /api/v3/sign-up endpoint try to perform bruteforce to /Sing-up, /SignUp, /singup...

Also try appending to the original endpoint bytes like %00, %0d%0a, %0d, %0a, %09, %0C, %20

Blank chars in code/params

Try adding some blank byte like %00, %0d%0a, %0d, %0a, %09, %0C, %20 to the code and/or params. For example code=1234%0a or if you are requesting a code for an email and you only have 5 tries, use the 5 tries for example@email.com, then for example@email.com%0a, then for example@email.com%0a%0a, and continue...

Changing IP origin using headers

X-Originating-IP: 127.0.0.1
X-Forwarded-For: 127.0.0.1
X-Remote-IP: 127.0.0.1
X-Remote-Addr: 127.0.0.1
X-Client-IP: 127.0.0.1
X-Host: 127.0.0.1
X-Forwared-Host: 127.0.0.1


#or use double X-Forwared-For header
X-Forwarded-For:
X-Forwarded-For: 127.0.0.1

If they are limiting to 10 tries per IP, every 10 tries change the IP inside the header.

Change other headers

Try changing the user-agent, the cookies... anything that could be able to identify you.

Adding extra params to the path

If the limit in in the path /resetpwd, try BFing that path, and once the rate limit is reached try /resetpwd?someparam=1

Login in your account before each attempt

Maybe if you login into your account before each attempt (or each set of X tries), the rate limit is restarted. If you are attacking a login functionality, you can do this in burp using a Pitchfork attack in setting your credentials every X tries (and marking follow redirects).
