Request parameters for lookup (domain)

Standard parameters

  • action = lookup
  • object = domain
  • registrant_ip = valid IP address of the registrant (optional) attributes

Attributes

Parameters within the attributes associative array are described below.

Parameter name

Obligation

Definition/Value

domain

Required

The domain name to be queried.

no_cache

Optional

In order to obtain results quickly, the default for the lookup command is to check the local OpenSRS cache to determine domain name availability. If you specify no_cache = 1, instead of checking the cache, the lookup command queries the applicable registry to determine domain name availability.
Note: Setting no_cache to 1 increases the amount of time it takes to get results.

Standard parameters

  • action = reply
  • object = domain
  • is_success = a Boolean is returned, indicating success or failure of the request

📘

Even if the domain being queried is taken (response_code = 211), is_success is set to 1 because the query was successful. Therefore, be sure to check the response_code and response_text when reading the reply.

Examples for lookup (domain) for Registry Premium Domains

📘

Please note: The response generated when querying a registry premium domain with lookup (domain) is dependent upon which registry premium domains the reseller has enabled. An available registry premium domain will appear unavailable or "taken" if the reseller has not enabled the tier of registry premium domains into which the domain falls.
