# Simple SPV Client

A simple SPV client that aims for easy integration primarily with LBRY Hub servers.

> The client isn't perfect. It can and will break if your input isn't correct.

To see what methods that the SPV will answer on, check [this website](https://electrumx.readthedocs.io/en/latest/protocol-methods.html).
This client doesn't try to decode the data recieved, rather it gives you the raw JSONRPC that the SPV replied with.

The claimtrie methods specific to LBRY will return a Base64 encoded protobuf as the result. You'll need to decode the result according to the [LBRY types](https://github.com/lbryio/types).
