GM. Blockstream.info blocks Tor users from using their API (frequently, but not 10% of the time)

If you are a privacy advocate and you are using them, I'd suggest setting up your own server or switching to another provider.

If you have a suggestion for privacy respecting alternatives, post 'em here!

The next one I am going to investigate is blockcypher. I'll report back on how they fare once I've done some testing.
