Heads up! - Restriction for some API functions - if you pull data, read this. was created by Simomax
Hello everyone,

It became apparent today that some users have automated the use of the CSV/graph drawing and other API functions, which has been having an impact on server performance. It was this thread that prompted me to have a bit of a dig through the radmon logs and found a lot of requests from external devices that have been using CPU intensive API functions. I have now restricted these functions for the time being until Dan and I find a suitable solution.

For now the following functions have been restricted:
  • forcegraphrefresh
  • drawall
  • graphtoday
  • graphweek
  • graphmonth
  • graphquarter
  • drawgraph24hr
  • drawsmallgraph
I am also looking at other API functions that are currently being abused but are having a lesser impact than the graph generation.

Feel free to discuss/throw in any ideas.

Cheers

I have made another two changes to the API. The functions lastreading and lastreadingusv were being heavily spammed, over and over. It is now a requirement to use the station's data sending password with the function. Yes, this does mean that only the station owner can request this data now, unless they share their password. It's not ideal, but the best I can come up with for now.

Anyone that is pulling their station CPM or uSv/h should update their code to include their station's data sending password.

Function: lastreading
*Updated 24/05/2026 - added in password requirement
Parameters: user, password
Description: Displays the last reading of a station in CPM.
Example: https://radmon.org/radmon.php?function=lastreading&user=Simomax&password=datasendingpassword
Returns: '18 CPM on 2022-12-03 17:49:31UTC at Blackpool, Lancashire, United Kingdom'

Function: lastreadingusv
*Updated 24/05/2026 - added in password requirement
Parameters: user, password
Description: Displays the last reading of a station in uSv/hr.
Example: https://radmon.org/radmon.php?function=lastreadingusv&user=Simomax&password=datasendingpassword
Returns: '0.225 uSv/hr on 2022-12-03 17:45:31UTC at Blackpool, Lancashire, United Kingdom'

This is just an example of what I found whilst digging, which I consider completely unacceptable:
