BTC bitcoin.cz slush example:
<pre>
{
"pools": [
{
"url": "http://api.bitcoin.cz:8332",
"user": "myuser",
"pass": "mypass"
}
]
}
</pre>

BNCR miningpools.tk example:
<pre>
{
"pools": [
{

"user": "1PhiPScGSvucr9FXTeC2LCW8oK5Nr21fzb",
"pass": "password"
}
]
}
</pre>

BNCR solo mining example: (running local BNCR server)
<pre>
{
"pools": [
{
"url": "http://localhost:9335",
"user": "bancorcoin",
"pass": "password123"
}
],
"api-port" : "4028",

== Output Explained ==

Stats:
* "hashrates: 5s decaying / all-time average / all-time average (effective)"
* exponentially decaying average over the opt_log_interval

source README:
<pre>
Each column is as follows:
The number of devices and processors currently mining
Hottest temperature reported by any processor
20 second exponentially decaying average hash rate (configurable with --log
option)
An all time average hash rate
An all time average hash rate based on actual nonces found, adjusted for pool
reject and stale rate
The number of Accepted shares
The number of Rejected shares and stale shares discarded (never submitted),
and the percentage these are of total found.
The number of HardWare errors, and percentage invalid of nonces returned
