A QTUM blockchain REST and web socket API service for Qtumcore Node.
This is a backend-only service. If you're looking for the web frontend application, take a look at https://github.com/qtumproject/qtum-explorer.

$(npm bin)/qtumcore-node startThe API endpoints will be available by default at: http://localhost:3001/qtum-insight-api/
There add-on service available to extend the functionality of Qtumcore:
Note: You can use an existing QTUM data directory, however txindex, addressindex, timestampindex and spentindex needs to be set to true in qtum.conf, as well as a few other additional fields.
To protect the server, qtum-insight-api has a built it query rate limiter. It can be configurable in qtumcore-node.json with:
"servicesConfig": {
"qtum-insight-api": {
"rateLimiterOptions": {
"whitelist": ["::ffff:127.0.0.1"]
}
}
}Or disabled entirely with:
"servicesConfig": {
"qtum-insight-api": {
"disableRateLimiter": true
}
}Note: routePrefix can be configurable in qtumcore-node.json with:
"servicesConfig": {
"qtum-insight-api": {
"routePrefix": "insight-api",
}
}To reduce the load on the server, qtum-insight-api has opportunity to enable / disable logs.
Both enableApiLogs and enableContractsApiLogs can be configured in qtumcore-node.json with:
"servicesConfig": {
"qtum-insight-api": {
"enableApiLogs": true,
"enableContractsApiLogs": false
}
}Note: In the case below enableApiLogs overrides enableContractsApiLogs:
"servicesConfig": {
"qtum-insight-api": {
"enableApiLogs": false,
"enableContractsApiLogs": true
}
