* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loHttp = CreateObject('Chilkat.Http')

* Send HTTP requests to https://rdap.org/<type>/<object>, where <type> is the object type (one of domain, ip, autnum, entity etc)
* and <object> is the object identifier (eg example.com, 192.168.0.1, 64496, etc).

* For example, here's a lookup for "oracle.com"
loSbResponse = CreateObject('Chilkat.StringBuilder')
lnSuccess = loHttp.QuickGetSb("https://rdap.org/domain/oracle.com",loSbResponse)
IF (lnSuccess = 0) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loSbResponse
    CANCEL
ENDIF

lnStatusCode = loHttp.LastStatus
IF (lnStatusCode <> 200) THEN
    ? "Error response:"
    ? loSbResponse.GetAsString()
    ? "status code: " + STR(lnStatusCode)
    RELEASE loHttp
    RELEASE loSbResponse
    CANCEL
ENDIF

* Load the JSON response and examine..
