Installation

Everything runs from Docker.

docker-compose up

If the above fails, you may need to rebuild:

docker-compose build && docker-compose up

If the above also fails, you made need to delete and recreate the containers:

docker-compose rm && docker-compose build && docker-compose up

Stack

Nginx listens for API requests on port 8001, passing the requests to gunicorn through a socket (/run/gunicorn.sock). These requests are processed by Flask which makes queries to a MySQL database and the appropriate coin daemon.

API

Address

Traces all activity associated with a given address. For example, to get full details about the litecoin_testnet4 address n1dB69Ptu1HMt1tRqiueyJ1tsaj59qSjLn, visit:

• http://127.0.0.1:8001/api/address/litecoin_testnet4/n1dB69Ptu1HMt1tRqiueyJ1tsaj59qSjLn

Transaction

Shows all details about a specified txid. For example, to get full details about the litecoin_testnet4 txid 63b302aa3e97c29ae01edc5ca80777105efc1164e1dda9a255e9e86f93e3f714, visit:

• http://127.0.0.1:8001/api/tx/litecoin_testnet4/63b302aa3e97c29ae01edc5ca80777105efc1164e1dda9a255e9e86f93e3f714

In particular, this will show all coinbase, vin and vout contained in the transaction.

Block

Shows all txid found in a specified block. For example, to get full details about the litecoin_testnet4 block with hash 4557827abb0272c7dd3b6fae8485ff3d3d5aad876e207743660000555fc4567b, visit:
