Domain Availability Checker

Check domain registration status and registry events using public RDAP records. Submit one domain or a batch of names to check their current RDAP registration status.

What data can you extract?

Registration status and dates reflect the registry data returned through RDAP.

Field	Type	Description
success	boolean	Whether the lookup completed successfully; false is a reported value, while null means RDAP provided no flag.
domain	text	Normalized domain queried through RDAP; if RDAP omits its domain field, the Actor uses the requested normalized domain. Null when the input cannot be normalized.
available	boolean	True when RDAP indicates the domain can be registered; false when it has an active registration, null if status is unavailable.
registered	boolean	Whether the domain has a registry record; false is a reported value, while null means RDAP provided no flag.
status	text	Status reported for the domain lookup by RDAP; null when RDAP does not provide the value.
confidence	text	confidence for the domain lookup, assigned by RDAP; null when the source does not expose it.
source	text	Source or language label shown for the domain lookup by RDAP, in the format used by the source; null when it is omitted.
rdap_url	link	Rdap url for this domain lookup on RDAP; null when the source does not provide a URL.
rdap_status_code	number	Rdap status code shown for the domain lookup by RDAP, in the format used by the source; null when it is omitted.
rdap_events	array	Domain registry events with event action, date and registrar or registry from RDAP; an empty list when no entries are available.
nameservers	array	DNS nameserver hostnames listed in the RDAP record; an empty list when no entries are available.
message	text	Diagnostic text for the RDAP lookup; null when the request completes without an error.
error	text	Diagnostic text for the RDAP lookup; null when the request completes without an error.
status_code	number	HTTP status code from the Scrappa API when the lookup request fails; the RDAP response status is reported separately in rdap_status_code.
input_domain	text	Trimmed original input supplied for the lookup; a URL remains intact here even though RDAP is queried with its normalized host.

Use cases

• Brand teams can check candidate domains before shortlisting names.
• Web operations teams can compare RDAP status and registration events.
• Product teams can verify domain status during naming or migration work.

How to use

1. Open the Actor’s Input tab and start with the JSON below.
2. Put the supported targets in domains and use the identifier or URL format required by the RDAP registry directory.
3. Start the run and open its default dataset to inspect or download the rows.

{
  "domains": [
    "example.com"
  ]
}

The run dataset can be downloaded as JSON, CSV, Excel or another format offered by Apify.

Input

Field	Type	Required	Description

FAQ

Is it legal to collect public information?

This Actor is for information visible on the public source pages it reads. You are responsible for checking the source terms, privacy and copyright rules, and the laws that apply to your use.

How many records will a run return?

The result count depends on the input limits, pagination settings and what the source makes available. A small query or unavailable page can return fewer records, including none.

Can I call it through the API or connect it to other tools?

Yes. Send the same JSON input to POST https://api.apify.com/v2/acts/thescrappa~domain-availability-checker/runs, then read the run’s default dataset. Make, Zapier and n8n can start runs and pass dataset rows to the next step; Google Sheets can receive rows through those workflows or a dataset export.

What happens when a request fails?

Check the run log for the source or input error, correct the input and retry after a temporary source issue. A run can contain rows saved before a later request failed.

What does an RDAP result tell me about a domain?

Registration status and event details reflect the RDAP response. Missing event or confidence values mean the registry did not provide them.
