This README contains details about the cgminer RPC API
It also includes some detailed information at the end,
about using miner.php
If you start cgminer with the "--api-listen" option, it will listen on a
simple TCP/IP socket for single string API requests from the same machine
running cgminer and reply with a string and then close the socket each time
If you add the "--api-network" option, it will accept API requests from any
network attached computer.
You can only access the comands that reply with data in this mode.
By default, you cannot access any privileged command that affects the miner -
you will receive an access denied status message see --api-allow below.
You can specify IP addresses/prefixes that are only allowed to access the API
with the "--api-allow" option e.g. --api-allow W:192.168.0.1,10.0.0/24
will allow 192.168.0.1 or any address matching 10.0.0.*, but nothing else
IP addresses are automatically padded with extra '.0's as needed
Without a /prefix is the same as specifying /32
0/0 means all IP addresses.
The 'W:' on the front gives that address/subnet privileged access to commands
that modify cgminer (thus all API commands)
Without it those commands return an access denied status.
See --api-groups below to define other groups like W:
Privileged access is checked in the order the IP addresses were supplied to
"--api-allow"
The first match determines the privilege level.
Using the "--api-allow" option overides the "--api-network" option if they
are both specified
With "--api-allow", 127.0.0.1 is not by default given access unless specified
If you start cgminer also with the "--api-mcast" option, it will listen for
a multicast message and reply to it with a message containing it's API port
number, but only if the IP address of the sender is allowed API access
More groups (like the privileged group W:) can be defined using the
--api-groups command
Valid groups are only the letters A-Z (except R & W are predefined) and are
not case sensitive
The R: group is the same as not privileged access
The W: group is (as stated) privileged access (thus all API commands)
To give an IP address/subnet access to a group you use the group letter
in front of the IP address instead of W: e.g. P:192.168.0/32
An IP address/subnet can only be a member of one group
A sample API group would be:
--api-groups
P:switchpool:enablepool:addpool:disablepool:removepool:poolpriority:*
This would create a group 'P' that can do all current pool commands and all
non-priviliged commands - the '*' means all non-priviledged commands
Without the '*' the group would only have access to the pool commands
Defining multiple groups example:
--api-groups Q:quit:restart:*,S:save
This would define 2 groups:
Q: that can 'quit' and 'restart' as well as all non-priviledged commands
S: that can only 'save' and no other commands
The RPC API request can be either simple text or JSON.
If the request is JSON (starts with '{'), it will reply with a JSON formatted
response, otherwise it replies with text formatted as described further below.
The JSON request format required is '{"command":"CMD","parameter":"PARAM"}'
(though of course parameter is not required for all requests)
where "CMD" is from the "Request" column below and "PARAM" would be e.g.
the ASC/PGA number if required.
An example request in both formats to disable Hotplug:
hotplug|0
{"command":"hotplug","parameter":"0"}
The format of each reply (unless stated otherwise) is a STATUS section
followed by an optional detail section
From API version 1.7 onwards, reply strings in JSON and Text have the
necessary escaping as required to avoid ambiguity - they didn't before 1.7
For JSON the 2 characters '"' and '\' are escaped with a '\' before them
For Text the 4 characters '|' ',' '=' and '\' are escaped the same way
Only user entered information will contain characters that require being
escaped, such as Pool URL, User and Password or the Config save filename,
when they are returned in messages or as their values by the API
For API version 1.4 and later:
The STATUS section is:
STATUS=X,When=NNN,Code=N,Msg=string,Description=string|
STATUS=X Where X is one of:
W - Warning
I - Informational
S - Success
E - Error
F - Fatal (code bug)
When=NNN
Standard long time of request in seconds
Code=N
Each unique reply has a unigue Code (See api.c - #define MSG_NNNNNN)
Msg=string
Message matching the Code value N
Description=string
This defaults to the cgminer version but is the value of --api-description
if it was specified at runtime.
With API V3.1 you can also request multiple report replies in a single command
request
e.g. to request both summary and devs, the command would be summary+devs
This is only available for report commands that don't need parameters,
and is not available for commands that change anything
Any parameters supplied will be ignored
The extra formatting of the result is to have a section for each command
e.g. CMD=summary|STATUS=....|CMD=devs|STATUS=...
With JSON, each result is within a section of the command name
e.g. {"summary":{"STATUS":[{"STATUS":"S"...}],"SUMMARY":[...],"id":1},
"devs":{"STATUS":[{"STATUS:"S"...}],"DEVS":[...],"id":1},"id":1}
As before, if you supply bad JSON you'll just get a single 'E' STATUS section
in the old format, since it doesn't switch to using the new format until it
correctly processes the JSON and can match a '+' in the command
If you request a command multiple times, e.g. devs+devs
you'll just get it once
If this results in only one command, it will still use the new layout
with just the one command
If you request a command that can't be used due to requiring parameters,
a command that isn't a report, or an invalid command, you'll get an 'E' STATUS
for that one but it will still attempt to process all other commands supplied
Blank/missing commands are ignore e.g. +devs++
will just show 'devs' using the new layout
For API version 1.10 and later:
The list of requests - a (*) means it requires privileged access - and replies:
Request Reply Section Details
------- ------------- -------
version VERSION CGMiner=cgminer, version
API=API| version
config CONFIG Some miner configuration information:
ASC Count=N, <- the number of ASCs
PGA Count=N, <- the number of PGAs
Pool Count=N, <- the number of Pools
Strategy=Name, <- the current pool strategy
Log Interval=N, <- log interval (--log N)
Device Code=ICA , <- spaced list of compiled
device drivers
OS=Linux/Apple/..., <- operating System
Failover-Only=true/false, <- failover-only setting
ScanTime=N, <- --scan-time setting
Queue=N, <- --queue setting
Expiry=N| <- --expiry setting
summary SUMMARY The status summary of the miner
e.g. Elapsed=NNN,Found Blocks=N,Getworks=N,...|
pools POOLS The status of each pool e.g.
Pool=0,URL=http://pool.com:6311,Status=Alive,...|
devs DEVS Each available PGA and ASC with their details
e.g. ASC=0,Accepted=NN,MHS av=NNN,...,Intensity=D|
Last Share Time=NNN, <- standand long time in sec
(or 0 if none) of last accepted share
Last Share Pool=N, <- pool number (or -1 if none)
Last Valid Work=NNN, <- standand long time in sec
of last work returned that wasn't an HW:
Will not report PGAs if PGA mining is disabled
Will not report ASCs if ASC mining is disabled
pga|N PGA The details of a single PGA number N in the same
format and details as for DEVS
This is only available if PGA mining is enabled
Use 'pgacount' or 'config' first to see if there
are any
pgacount PGAS Count=N| <- the number of PGAs
Always returns 0 if PGA mining is disabled
switchpool|N (*)
none There is no reply section just the STATUS section
stating the results of switching pool N to the
highest priority (the pool is also enabled)
The Msg includes the pool URL
enablepool|N (*)
none There is no reply section just the STATUS section

of the device for appoximately 4s
All other non BFL,ICA PGA devices will return a
warning status message stating that they dont
support it. Non-CMR ICAs will ignore the command.
This adds a 4s delay to the BFL share being
processed so you may get a message stating that
procssing took longer than 7000ms if the request
was sent towards the end of the timing of any work
being worked on
e.g.: BFL0: took 8438ms - longer than 7000ms
You should ignore this

none There is no reply section just the STATUS section
stating that the zero, and optional summary, was
done
If Which='all', all normal cgminer and API
statistics will be zeroed other than the numbers
displayed by the usbstats and stats commands
If Which='bestshare', only the 'Best Share' values
are zeroed for each pool and the global
'Best Share'
The true/false option determines if a full summary
is shown on the cgminer display like is normally
displayed on exit.
hotplug|N (*) none There is no reply section just the STATUS section
stating that the hotplug setting succeeded
If the code is not compiled with hotplug in it,
the the warning reply will be

help message about the options available
The current options are:
AVA+BTB opt=freq val=256 to 1024 - chip frequency
BTB opt=millivolts val=1000 to 1400 - corevoltage
lockstats (*) none There is no reply section just the STATUS section
stating the results of the request
A warning reply means lock stats are not compiled
into cgminer
The API writes all the lock stats to stderr
When you enable, disable or restart a PGA or ASC, you will also get
Thread messages in the cgminer status window
The 'poolpriority' command can be used to reset the priority order of multiple
pools with a single command - 'switchpool' only sets a single pool to first
priority
Each pool should be listed by id number in order of preference (first = most
preferred)
Any pools not listed will be prioritised after the ones that are listed, in the
priority order they were originally
If the priority change affects the miner's preference for mining, it may switch
immediately
When you switch to a different pool to the current one (including by priority
change), you will get a 'Switching to URL' message in the cgminer status
windows
Obviously, the JSON format is simply just the names as given before the '='
with the values after the '='
If you enable cgminer debug (-D or --debug) or, when cgminer debug is off,
turn on debug with the API command 'debug|debug' you will also get messages
showing some details of the requests received and the replies
There are included 4 program examples for accessing the API:
api-example.php - a php script to access the API
usAge: php api-example.php command
by default it sends a 'summary' request to the miner at 127.0.0.1:4028
If you specify a command it will send that request instead
You must modify the line "$socket = getsock('127.0.0.1', 4028);" at the
beginning of "function request($cmd)" to change where it looks for cgminer
API.java/API.class
a java program to access the API (with source code)
usAge is: java API command address port
Any missing or blank parameters are replaced as if you entered:
java API summary 127.0.0.1 4028
api-example.c - a 'C' program to access the API (with source code)
usAge: api-example [command [ip/host [port]]]
again, as above, missing or blank parameters are replaced as if you entered:
api-example summary 127.0.0.1 4028
miner.php - an example web page to access the API
This includes buttons and inputs to attempt access to the privileged commands
See the end of this API-README for details of how to tune the display
and also to use the option to display a multi-rig summary

miner.php
=========
miner.php is a PHP based interface to the cgminer RPC API
(referred to simply as the API below)
It can show rig details, summaries and input fields to allow you to change
cgminer
You can also create custom summary pages with it
It has two levels to the security:
1) cgminer can be configured to allow or disallow API access and access level
security for miner.php
2) miner.php can be configured to allow or disallow privileged cgminer
access, if cgminer is configured to allow privileged access for miner.php
---------
To use miner.php requires a web server with PHP
Basics: On xubuntu 11.04, to install apache2 and php, the commands are:
sudo apt-get install apache2
sudo apt-get install php5
sudo /etc/init.d/apache2 reload
On Fedora 17:
yum install httpd php
systemctl restart httpd.service
systemctl enable httpd.service --system
On windows there are a few options.
Try one of these (apparently the first one is easiest - thanks jborkl)
http://www.easyphp.org/
http://www.apachefriends.org/en/xampp.html
http://www.wampserver.com/en/
---------
The basic cgminer option to enable the API is:
--api-listen
or in your cgminer.conf
"api-listen" : true,
(without the ',' on the end if it is the last item)
If the web server is running on the cgminer computer, the above
is the only change required to give miner.php basic access to
the cgminer API
-
If the web server runs on a different computer to cgminer,
you will also need to tell cgminer to allow the web server
to access cgminer's API and tell miner.php where cgminer is
Assuming a.b.c.d is the IP address of the web server, you
would add the following to cgminer:
--api-listen --api-allow a.b.c.d
or in your cgminer.conf
"api-listen" : true,
"api-allow" : "a.b.c.d",
to tell cgminer to give the web server read access to the API
You also need to tell miner.php where cgminer is.
Assuming cgminer is at IP address e.f.g.h, then you would
edit miner.php and change the line
$rigs = array('127.0.0.1:4028');
to
$rigs = array('e.f.g.h:4028');
See --api-network or --api-allow for more access details
and how to give write access
You can however, also tell miner.php to find your cgminer rigs automatically
on the local subnet
Add the following to each cgminer:
--api-mcast
or in your cgminer.conf
"api-mcast" : true,
And in miner.php set $mcast = true;
This will ignore the value of $rigs and overwrite it with the list of zero or
more rigs found on the network in the timeout specified
A rig will not reply if the API settings would mean it would also ignore an
API request from the web server running miner.php
