Can I use Echelon without a subscription?

Good day, fellow cryptocurrency enthusiasts. I've been exploring the various tools and platforms available in the crypto space, and Echelon has piqued my interest. However, I'm wondering if I can utilize its features and services without having to subscribe to a paid plan. My concern is that, while I'm still new to the crypto world, I don't want to commit to a long-term subscription right away. Is there a free version or a trial period that allows me to test the waters first? Any insights or experiences you've had with Echelon, either as a subscriber or a non-subscriber, would be greatly appreciated. Thank you in advance for your valuable input.
