If you exceed the rate limit of your plan, the API will respond with an error. For exceeding the allowed number of concurrent requests, you'll receive a 430 error code. If your request frequency within a minute surpasses your plan's allowance, you'll encounter a 429 error code.
To avoid service interruptions and ensure optimal use of the API, we advise monitoring your usage closely. If you consistently hit or go beyond these rate limits, upgrading your plan may be necessary.
