With the recent launch of VSC mainnet earlier this month, I'm announcing my new public VSC API endpoints for general use along with other related developments.
GraphQL Endpoint
This is the standard API endpoint that is part of go-vsc-node. There is an Apollo sandbox (pictured above) that anyone may experiment with, however take note that around half of the query methods are still WIP.
This endpoint was formerly known as vsc-graphql.techcoderx.com during the previous testnet.
Endpoint: https://vsc.techcoderx.com/api/v1/graphql
Sandbox UI: https://vsc.techcoderx.com/sandbox
VSC Blocks Backend
A new backend specific to VSC Blocks has been developed which provides the following services:
Contract Verifier
This verifies VSC contracts by compiling the uploaded contract source code and comparing the resulting output bytecode against the deployed contract bytecode. It supports AssemblyScript contracts at this moment with more languages to come.

Indexer and REST API
The backend also indexes additional information on top of the VSC node database mostly for analytical purposes. This currently provides election/block participation rates, witness/bridge stats and sequential block numbers.
The API lives in https://vsc.techcoderx.com/be-api/v1 namespace, documentation to be made available here.
