Add http rest API about btc-rpc-explorer

[janoside]

We have an API, finally! See it on the demo site at https://bitcoinexplorer.org/api/docs

This is available now for source installations and will be included in the next release coming soon.

REST API would be great, +1

Was the feature implemented ? Would be great to access JSON requests on page without need to go on the tabs

[fellowworldcitizen]

+1! JSON is already there! Could be as simple as adding json/1 to URL. Then show json as: [{"tabname1":json1},{"tabname2":json2}].

There's already an API that's not documented.
See the routes/ApiRouter.js
Here's an example.
https://explorer.btc21.org/api/blocks-by-height/1

So, I presume the task would be to add more routes to that ApiRouter that reuse some logic from the routes that return HTML but instead return JSON.

And a task to make the ApI documentation.

Here's an API for a raw transaction:
