Hi!

I'm looking for a robust API allowing access to testnet3 (pushing txs, browsing utxos, etc).
I was using blockcypher, but it hasn't performed well. Chain.so API was good, but now it disappeared. Smartbit API was also pretty decent and recently it also disappeared.

Do you have anything else to recommend?
Or maybe a tutorial how to kick off own testnet node and hit it with jsonrpc calls? (Note that in my case regtest is not an option, I need a connection to testnet)
Or maybe I can find somewhere list of well-known testnet node urls with exposed json-rpc endpoint?

I don't generate heavy traffic, but still finding something that will last more than few months is difficult.
Please advice. I'm totally lost.

Cheers.
