BCHD is an alternative full node bitcoin cash implementation written in Go (golang) that allows for easy querying of the blockchain. It may be used as an alternative to rest.bitcoin.com.
BCHD now has SLP indexing built into it. Here is a quick overview of some of the features:
Receive SLP metadata on transactions, tokens, all from one source. This allows you to do one query and not have to worry about synchronizing issues like when using SLPDB.
Burn Protection -- you can be sure that you aren't burning any SLP tokens due to a bug in your software. If you do want to burn some tokens that still works too, just enumerate them. You can check SLP validity prior to broadcasting or during broadcast.
Parse and create SLP metadata. You can use this inside your application when constructing your transactions.
Subscribe to all transactions involving specific tokens.
