InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
It's pretty cheap and easy to run your own node and fulcrum server. You can also connect to a fulcrum/electrum cluster (there are many public servers, just check 1209k.com) using for example https://gitlab.com/GeneralProtocols/electrum-cash
