Rate limits

Updated API rate limits

Rate limits will be updated on June 6, 2025. Rate limits will change from the IP level to the Organization level.

Updated rate limits (Click to expand)

Updated limits:

Description	Rate limit
Unauthenticated requests	100 requests per 5 minutes
Entities API requests	35,000 requests per 5 minutes
All other API requests	15,000 requests per 5 minutes

Check the rate limit status

Each API response includes headers that provide information about your current rate limit status:

Header name	Description
x-ratelimit-period	The time in seconds which defines the rate limit window
x-ratelimit-limit	The maximum number of requests that you can make in during the rate limit window
x-ratelimit-remaining	The number of requests remaining in the current rate limit window
x-ratelimit-reset	The time at which the current rate limit window resets, in UTC epoch seconds

For the current rate limits, read on below.

Rate limits restrict the number of requests or actions allowed within a certain timeframe to prevent overuse or abuse. Port enforces multiple rate limits to control extensive usage of Port's API.

Port's rate limits vary based on the API being accessed and may be more lenient for some APIs.
Rate limits are enforced at the IP level.

Rate limits table

Description	Rate limit
Unauthenticated requests	100 requests per 5 minutes
Ocean integrations	20,000 requests per 5 minutes
External exporters	15,000 requests per 5 minutes
IaC integrations and CI/CD actions	5,000 requests per 5 minutes
Entity API requests	5,000 requests per 5 minutes
All other API requests	2,500 requests per 5 minutes

How to prevent getting rate limited

Use exponential backoff

Exponential backoff is a technique used to prevent overwhelming a server with too many requests in a short period of time. It involves progressively increasing the delay between retries when encountering rate limits or server errors.

To implement exponential backoff, you can follow these steps:

1. Define a base delay: Start with a small delay, such as 1 second, as the base delay for the first retry.
2. Define a maximum number of retries: Determine the maximum number of retries you want to attempt before giving up.
3. Implement retry logic: Wrap your API request code in a retry loop that will retry the request if it encounters a rate limit or server error.
4. Calculate the delay: Use an exponential function to calculate the delay for each retry. The delay can be calculated using the formula: delay = baseDelay * (2 ^ retryCount), where retryCount starts from 0 for the first retry.
5. Apply the delay: Before each retry, pause the execution of the code for the calculated delay duration.

Here's are examples of how you can implement exponential backoff:

Python

import time

base_delay = 1  # 1 second
max_retries = 5
max_delay = 32

def make_api_request():
    # Your API request code goes here
    pass

def retry_with_exponential_backoff():
    attempt = 0
    delay = base_delay
    
    while attempt < max_retries:
        try:
            result = make_api_request()
            return result
        except Exception as e:
            attempt += 1
            if attempt >= max_retries:
                raise e
            sleep_time = min(delay * (2 ** attempt), max_delay)
            print(f"Attempt {attempt} failed. Retrying in {sleep_time:.2f} seconds...")
            time.sleep(sleep_time)
    raise Exception("All retry attempts failed.")

retry_with_exponential_backoff()

Javascript

const baseDelay = 1000; // 1 second
const maxRetries = 5;
let retryCount = 0;

function makeApiRequest() {
  // Your API request code goes here
}

function retryWithExponentialBackoff() {
  if (retryCount < maxRetries) {
    const delay = baseDelay * Math.pow(2, retryCount);
    setTimeout(() => {
      retryCount++;
      makeApiRequest();
    }, delay);
  } else {
    console.log('Exceeded maximum retries');
  }
}

retryWithExponentialBackoff();

In this example, the makeApiRequest function represents your actual API request code. The retryWithExponentialBackoff function is responsible for calculating the delay and retrying the request using exponential backoff. It uses the setTimeout function to pause the execution for the calculated delay duration. Remember to adjust the baseDelay and maxRetries values according to your specific requirements.

Exponential backoff helps to distribute the load on the server and increases the chances of a successful request without exceeding rate limits.
