The rate limit policy for our infra is pretty simple. Every account gets an allocated bandwidth of N requests / second depending on its tier. Exceeding that request limit will result in a failed request with the error code 429 Too Many Requests. You can read more about the different tiers here.
If you find yourself in need of a larger rate limit than what is offered by our default plans, feel free to contact our customer support and we'll help tailor a plan that suits your needs.
Important Note
In order to protect our servers from malicious activities, we enforce the rate limit policies in a strict way. Repeated attempts at circumventing this limit for an extended period of time may result in account suspension or outright termination in accordance with our Terms of Service.
