How to get ip prefixes from children of given as number?

Question

So, for example I have as number as10282 how I can get ip prefixes of children for the given as number?

bgp lookup tool

Given tool is exactly what I need (with ticked include downstream prefixes), but I need to implement it in my application, how to do this? I tried with parsing ripe output of "whois" query but I did not get far, because I do not get always same output I used query (whois -B -h whois.ripe.net -i mb NAME)

In order to get a view like this of the live BGP global network, you will need your own actual BGP feed. Looking in RIPE or other databases will only show you what people have been assigned, not what they're actually announcing right now. i.e, you can't do this 'yourself', you need an external source of data.
