1. Summary
This article describes how to use the whatsminer’s API. The intended audience is mine management software developers. The mine management software functions similar to WhatMinerTool can be realized through the API.
The API read permission is granted by default, and the API write permission needs to be enabled through the WhatMinerTool, follow these steps:
1. Change the default password(admin);
2. Enable the API
2. Protocol
The whatsminer API TCP port is 4028.
Notice:
1. If no data is received within 10 seconds after the port is connected, the
connection will time out and be closed.
2. Miner supports max 16 IP clients, one IP can get 32 tokens, and a token
keepalive time is 30 minutes.
JSON API return format:
{
“STATUS”:”string”,
“When”:12345678, #integer
“Code”:133,
“Msg”:”string”, #string or object
“Description”:”string”,
}
Message Code:
| Code | Message |
| 14 | invalid API command or data |
| 23 | invalid JSON message |
| 45 | permission denied |
| 131 | command OK |
| 132 | command error |
| 134 | get token message OK |
| 135 | check token error |
| 136 | token over max times |
| 137 | base64 decode error |
2.1 API ciphertext
Notice: the readable API supports two communication modes: plaintext and
ciphertext; the writable API supports only ciphertext communication.
Encryption algorithm:
Ciphertext = aes256(plaintext)，ECB mode
Encode text = base64(ciphertext)
Steps as follows:
(1)api_cmd = token,$sign|api_str
(2)enc_str = aes256(api_cmd, $key)
(3)tran_str = base64(enc_str)
api_str is API command plaintext
Generate aeskey step：
(1)Get token from miner: $time $salt $newsalt
(2)Generate key:
key = md5(salt + admin_password)
Reference code:
key = `openssl passwd -1 -salt $salt “${admin_password}”`
(3)Generate aeskey:
aeskey = sha256($key)
e.g.:
set_led|auto ->
token,$sign|set_led|auto ->
ase256(“token,sign|set_led|auto”, $aeskey) ->
base64(ase256(“token,sign|set_led|auto”, $aeskey) ) ->
enc|base64(ase256(“token,sign|set_led|auto”, $aeskey))
JSON:
{
“enc”:1, # integer
“data”:”base64 str”
}
2.2 The flow
3. Writable API
Writable API only supports ciphertext.
The writable API must first obtain the token as follows:
JSON:
client -> miner：
{“cmd”:”get_token”}
miner -> client：
{“time”:”str”,”salt”:”str”,”newsalt”:”str”}
e.g.：
{“time”:”5626″,”salt”:”BQ5hoXV9″,”newsalt”:”jbzkfQls”}
time: timestamp, this count starts at the Unix Epoch on January 1st, 1970 at UTC.
salt: a random salt is generated for each password
newsalt: new salt for sign
Token calculation method:
Get token from miner: time salt newsalt.
1. calculate key use admin’s password and salt.
2. time is the last four characters of time .
key = md5(salt + admin_password)
sign = md5(newsalt + key + time)
The reference code in Ubuntu:
First, Get those values from miner: $time $salt $newsalt.
Ubuntu Shell command:
key = `openssl passwd -1 -salt $salt “${admin_password}”|cut -f 4 -d ‘$’`
sign=`openssl passwd -1 -salt $newsalt “${key}${time:0-4}”|cut -f 4 -d ‘$’`
The default user name and password are admin

JSON:
{
“cmd”: “set_power_pct”,
“percent”: “str”, #range: 0 ~ 100

3.22 Pre power on
The miner can be preheated by “pre_power_on” before “power on”, so that the machine
can quickly enter the full power state when “power on” is used. You can also use this
command to query the pre power on status. Make sure power_off btminer before
pre_power_on.
“wait for adjust temp”: The temperature adjustment of the miner is not completed.

be power on.

The faster the speed, the greater the final hash rate and power deviation, and the stability
may have a certain impact. Fast boot mode cannot be used at the same time.
