Insight API RAPTURE

A RAPTURE blockchain REST and web socket API service for Bitcore Node Rapture

This is a backend-only service.

Getting Started

``bashl
npm install -g bitcore-node-rapture@latest
bitcore-node-rapture create mynode
cd mynode
bitcore-node-rapture install insight-api-rapture
bitcore-node-rapture start
`

The API endpoints will be available by default at: http://localhost:3001/insight-api-rapture/

Prerequisites

- Bitcore Node RAPTURE 3.x

Note: You can use an existing RAPTURE data directory, however txindex, addressindex, timestampindex and spentindex needs to be set to true in rapture.conf, as well as a few other additional fields.

Notes on Upgrading from v0.3

The unspent outputs format now has satoshis and height:
`
[
{
"address":"mo9ncXisMeAoXwqcV5EWuyncbmCcQN4rVs",
"txid":"d5f8a96faccf79d4c087fa217627bb1120e83f8ea1a7d84b1de4277ead9bbac1",
"vout":0,
"scriptPubKey":"76a91453c0307d6851aa0ce7825ba883c6bd9ad242b48688ac",
"amount":0.000006,
"satoshis":600,
"confirmations":0,
"ts":1461349425
},
{
"address": "mo9ncXisMeAoXwqcV5EWuyncbmCcQN4rVs",
"txid": "bc9df3b92120feaee4edc80963d8ed59d6a78ea0defef3ec3cb374f2015bfc6e",
"vout": 1,
"scriptPubKey": "76a91453c0307d6851aa0ce7825ba883c6bd9ad242b48688ac",
"amount": 0.12345678,
"satoshis: 12345678,
"confirmations": 1,
"height": 300001
}
]
`
The timestamp property will only be set for unconfirmed transactions and height can be used for determining block order. The confirmationsFromCache is nolonger set or necessary, confirmation count is only cached for the time between blocks.

There is a new GET endpoint or raw blocks at /rawblock/:

Response format:
`
{
"rawblock": "blockhexstring..."
}
`

There are a few changes to the GET endpoint for /addr/[:address]:

- The list of txids in an address summary does not include orphaned transactions
- The txids will be sorted in block order
- The list of txids will be limited at 1000 txids
- There are two new query options "from" and "to" for pagination of the txids (e.g. /addr/[:address]?from=1000&to=2000)

Some additional general notes:
- The transaction history for an address will be sorted in block order
- The response for the /sync endpoint does not include startTs and endTs as the sync is no longer relevant as indexes are built in bitcoind.
- The endpoint for /peer is no longer relevant connection to bitcoind is via ZMQ.
- /tx endpoint results will now include block height, and spentTx related fields will be set to null if unspent.
- /block endpoint results does not include confirmations and will include poolInfo.

Notes on Upgrading from v0.2

Some of the fields and methods are not supported:

The /tx/ endpoint JSON response will not include the following fields on the "vin"
object:
- doubleSpentTxId // double spends are not currently tracked
- isConfirmed // confirmation of the previous output
- confirmations // confirmations of the previous output
- unconfirmedInput

The /tx/ endpoint JSON response will not include the following fields on the "vout"
object.
- spentTs

The /status?q=getTxOutSetInfo method has also been removed due to the query being very slow and locking bitcoind.

Plug-in support for Insight API is also no longer available, as well as the endpoints:
- /email/retrieve
- /rates/:code

Caching support has not yet been added in the v0.3 upgrade.

Query Rate Limit

To protect the server, insight-api has a built it query rate limiter. It can be configurable in bitcore-node.json with:
` json
"servicesConfig": {
"insight-api": {
"rateLimiterOptions": {
"whitelist": ["::ffff:127.0.0.1"]
}
}
}
`
With all the configuration options available: https://github.com/bitpay/insight-api/blob/master/lib/ratelimiter.js#L10-17

Or disabled entirely with:
` json
"servicesConfig": {
"insight-api": {
"disableRateLimiter": true
}
}
`

Web Socket API

The web socket API is served using socket.io.

The following are the events published by insight:

tx: new transaction received from network, txlock boolean is set true if a matching txlock event has been observed. This event is published in the 'inv' room. Data will be a app/models/Transaction object.
Sample output:
`
{
"txid":"00c1b1acb310b87085c7deaaeba478cef5dc9519fab87a4d943ecbb39bd5b053",
"txlock": false,
"processed":false
...
}
`

txlock: InstantSend transaction received from network, this event is published alongside the 'tx' event when a transaction lock event occurs. Data will be a app/models/Transaction object.
Sample output:
`
{
"txid":"00c1b1acb310b87085c7deaaeba478cef5dc9519fab87a4d943ecbb39bd5b053",
"processed":false
...
}
`

block: new block received from network. This event is published in the inv room. Data will be a app/models/Block object.
Sample output:
`
{
"hash":"000000004a3d187c430cd6a5e988aca3b19e1f1d1727a50dead6c8ac26899b96",
"time":1389789343,
...
}
`

: new transaction concerning received from network. This event is published in the room.

status: every 1% increment on the sync task, this event will be triggered. This event is published in the sync room.

Sample output:
`
{
blocksToSync: 164141,
syncedBlocks: 475,
upToExisting: true,
scanningBackward: true,
isEndGenesis: true,
