You can have a glance at current measurements of the prototype:
The most recent data point The last 24h

• maxlen is limited to 1000, and represents the number of data points
• history is a value in hours (max. xxx hours in the past)
• key[1] is the public key of the prototype

The result is in the form

<publicKey>&<date-time>&<temperature>&<battery>

Example:

AtAH8ziYVr&2015-04-04 01:43:49&0.31&59.1 

Means: 0.31°C and 59.1% battery
