Linden Lab Official:Reg API Examples
Second Life APIs
The following examples illustrate using the Reg API to register a new user with a specified Second Life first name and last name. The example code first checks to determine the availability of the selected first and last name, and either registers the user or returns an error message if the name is already taken.
LLSD library downloads
To use a library:
- Remove the -lib suffix from the file name.
- Put the file in the same directory as the application code, such as the examples below.
- Ruby LLSD library (version 1.3)
- PHP LLSD library (version 1.0)
- Python LLSD library (version 1.2)
- Perl LLSD library (version 1.0)
NOTE: The PHP scripts only work with PHP4.
An externally developed Java implementation of LLSD and RegAPI is available at http://mimuve.cs.st-andrews.ac.uk/llsd-java/src/llsd-java-0.2.1.zip . Code written by Xugu Madison, copyright held by University of St Andrews, and made available under the BSD license. Tested with Java 1.5.
Question: what version of each language is required?
Example code
Ruby
This ruby example shows how to use the Registration API.

- 1 - get error codes
- 2 - get the available last names
- 3 - check to see of a username + last name combo is taken
- 4 - register the user with this username + last name combo
get_capabilities_url = "https://cap.secondlife.com/get_reg_capabilities"
- grab command line args
