Fixer API Coupon Codes October 2026 – 29 Verified Offers

Consistent performance, as usual

I've been using Fixer API for a while now, mostly for the Historical Exchange Rates. This time, I upgraded to the Professional Plan for more calls and historical depth. The data quality and reliability are still top-notch, just as I've come to expect from previous uses. It integrates smoothly every time. My only minor complaint is that the upgrade process felt a tiny bit clunky; it could be more streamlined.

Works well, quick setup

Needed the Currency Fluctuation API for a client. Set up was fast. Data seems accurate. Got what I paid for. The documentation could use a bit more example code, but it was fine.

Easy to use for my side project

So I was messing around with a little side project that needed currency conversions, and my friend suggested Fixer API. I just got the Basic Plan. It was super easy to get set up; barely took me any time at all. The documentation was clear enough, which is always nice. Everything worked as expected. It's a solid service for what I needed, though sometimes the dashboard feels a bit too simple, like it could use a few more quick-access stats.

Smooth integration, few hiccups

I purchased the Professional Plus Plan for my startup's multi-currency conversion tool. The ordering process on their site was clear, and I received my API key almost instantly. Integration with our Node.js backend was surprisingly smooth, and the documentation was helpful. The real-time currency conversion API has been very reliable, updating frequently as advertised. I also tested the Historical Exchange Rates API, which returned data quickly. The only minor point is that sometimes the dashboard takes a second or two longer to load than I'd expect, but that doesn't affect API performance at all. Overall, a solid service for forex data.

Great value with annual plan

I was looking for a good deal on a currency API and found Fixer. I chose the Professional Plus Plan with annual billing. It saved me a good chunk of money compared to monthly. The features are robust, and it covers all the currencies I need. It feels like a solid investment for my app. Just wish there was a clear student discount option when I signed up, but the annual saving was good enough.

Good API, fast setup

I needed the Latest Rates Endpoint for a small project. Setup was quick. Data was accurate. Had a small question about limits, but found the answer myself. Overall, it worked well.

Good data, small pricing confusion

I signed up for the Professional Plan last month to get real-time rates for a small project. The API itself is very fast and the data for the 170+ currencies was accurate, which is crucial. I found integrating the JSON API for developers fairly straightforward. My only slight issue was that the pricing page initially felt a little unclear on the exact differences between the Professional and Professional Plus plans regarding historical data access, but I figured it out eventually. Overall, good value for what you get.

So easy to use!

Got the Basic Plan for my side project and it's fantastic! The Latest Rates Endpoint was super easy to integrate with my Python script. Everything just worked perfectly. I had a quick question about rate limits for the free tier before upgrading and customer support answered it fast. I'm definitely subscribing again next year!
