Consistent performance, always reliable

I've been using Coinlayer for over a year now, mainly for the Real-time Crypto Exchange Rates API. This latest order for the Enterprise plan was just as smooth as previous upgrades. The data quality has been consistently high, and I haven't had any unexpected downtimes, which is crucial for my application. They're reliable, and that's why I keep coming back instead of trying other providers.

Excellent crypto data API

I am so happy with Coinlayer! I needed the Historical Crypto Data API for a backtesting project, and it delivered perfectly. The JSON API Response was clean and easy to parse, and the data coverage for altcoins was really impressive. I got everything set up much faster than I thought I would. This is exactly what I was looking for, and I will absolutely be using them again. Highly recommend for any developer needing crypto data!

Decent data, slow delivery

I tried Coinlayer for their Historical Crypto Data API for a project. Ordering was straightforward on their website. I got my API key quickly, but it took about 4 days for the initial historical data dump to fully sync and be available without rate limiting issues, which was a bit longer than I anticipated. Once it was all set up, the data itself was quite good and comprehensive, covering many obscure altcoins. The API Management Dashboard is functional, though a bit basic. Customer support responded within a day when I inquired about the data availability delay, so that was okay.

Solid data, small issue

I used the Real-time Crypto Exchange Rates API for a small application. The data was accurate and came through quickly, which was great. Setting up the API key was straightforward with their documentation. My only minor gripe was that the developer documentation could be a little more organized; I spent a bit of time looking for specific examples. But once I got it going, it worked as expected. Pretty good value for the cost.

Good data, minor setup hiccup

I signed up for the Professional plan last month to get access to the Live WebSocket Stream and overall, it's been pretty solid. The real-time data for altcoins is accurate and the API documentation was clear. My main gripe was with the initial setup for the WebSocket; it took a bit more digging in the docs than I expected to get it fully configured with my dev environment. Once that was sorted, everything ran smoothly. Value for money is good, especially compared to some competitors.

Good value on annual plan

I was looking for a reliable crypto API without breaking the bank. I signed up for the Professional Plan and opted for annual billing to get the 20% discount. That made it feel like a much better deal overall. The API Management Dashboard is easy to use, and I got my API key instantly. It felt like I got a lot of features for what I paid, definitely worth the purchase for my project.

Great value for API data

As a first-time buyer, I was looking for the best deal on crypto data. I opted for the annual billing to get the 20% off on the Basic plan. It felt like a smart move. The developer trial was helpful to test things out. The JSON API Response was easy to integrate, and the data for Bitcoin and Ethereum was exactly what I needed. Definitely a good return on my investment.

API worked quickly

Needed the Crypto Conversion Endpoint. Signed up, got API key fast. Data was accurate. Good service.
