• The default response format is plain text. To receive the response in HTML or XML format, send ResponseType=HTML or ResponseType=XML in your request.
• Check the return parameter ErrCount. If greater than 0 the transaction failed. The parameter Err(ErrCount) can be presented to the client. Otherwise process the returned parameters as defined above.
• When parsing the response, use the RRPCode value rather than the RRPText value or the position in the response. Of these, only the RRPCode value is guaranteed by the Registry to be stable.
• Pricing information will be returned if the domain name is a gTLD, if the name is Premium, if the TLD is in EAP, or any combination of these cases. Pricing will not be returned if the TLD is a legacy TLD in general availability.
• .TV is used in the sample code below, but .TV is the only TLD that does not return pricing information in the <check> response.
