Keeping an eye on your weather API usage is key to managing costs, optimizing data retrieval, and staying within rate limits. This ensures your apps run smoothly for users.

Modern weather APIs, like Tomorrow.io, offer tools to track API usage efficiently. This is vital for operational efficiency, preventing service disruptions, and making the most of weather data in your projects. With Tomorrow.io, you get insights into your API interactions, helping you manage and optimize your app’s performance.



Tomorrow.io's Rate Limits

Before we get into monitoring API usage, let’s understand Tomorrow.io’s rate-limiting structure. Tomorrow.io sets rate limits on its weather API to ensure fair usage and maintain performance.

These limits help manage server load and prevent resource overconsumption by any single user, ensuring quality service for all. By sticking to these limits, users can consistently access accurate weather data and promote efficient API usage. Here are the rate limits for Tomorrow.io’s free plan:

  • 500 requests per day,

  • 25 requests per hour,

  • 3 requests per second.

You can find more information about the free plan API rate limits here.

How to Monitor API Usage

To monitor your weather API usage, you must first sign in to your Tomorrow.io account and head out to the development section. Here, you can find your API key and review your latest API calls, the methods, and the status codes. Let's take a look at what the Activity Dashboard looks like:

The graph above shows the API calls we've made over the last week, their timestamp, as well as their status codes.

Alternatively, you can monitor your API usage programmatically, as explained in the rate-limiting section of the documentation. Here are the headers you should look for:

X-RateLimit-Limit-second
X-RateLimit-Limit-day
X-RateLimit-Limit-hour

X-RateLimit-Remaining-second
X-RateLimit-Remaining-day
X-RateLimit-Remaining-hour

However, please keep in mind that getting the remaining rate limits in the response's header is currently available only for Enterprise accounts.

As for Tomorrow.io customers who are using the token structure, they can find the following headers in the response:

X-Tokens-Cost-{product}
X-Tokens-Remaining-{product}

Optimizing Weather API Usage: Best Practices and Strategies

When using weather APIs, it’s key to adopt best practices to ensure your app runs smoothly and stays within operational limits. Start proactive monitoring early in the development process to catch and fix potential issues before they affect your app. Consider implementing caching mechanisms to reduce API calls, which helps preserve your rate limit and boost performance.

Lastly, optimizing your requests is vital. Try batching requests where possible and limit your queries to only the necessary data fields. These strategies not only help you stick to Tomorrow.io’s rate limits but also enhance your app’s efficiency and reliability when using weather data.
