WHOIS History API

Get the historical WHOIS records of a domain name.

Our Historical WHOIS Database contains WHOIS history (over 1.33 Billion records) of every domain name (over 525 Million) that was ever registered on the Internet. Historical WHOIS Database contains WHOIS of current as well as expired and deleted domain names. Using our WHOIS History API, you can fetch the historical WHOIS records of any domain name that was ever registered. The result will contain the full WHOIS data for each historical record.

Get the WHOIS history of any domain name through the following API:

https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com

Replace the key "XXXXX" with your own API key, generated through the Members Area.

Cost for Single Query = (2 API Credits for 100 Results)

XML Format

By default, all results are sent in JSON format. To get results in XML format, simply add "&format=xml" to your query.

https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&format=xml

Cost for Single Query = (Same as with JSON Format)

Count Total Results

The total count of results for your query will be provided in the following format:

"count": { "total": 35, "relation": "eq", "current": 35 }

Generally the total results count can't be computed accurately without visiting all matches, which is costly for queries that match lots of documents. So, the API will count the total accurately up to 10,000 results. It is a good trade-off to speed up searches if you don't need the accurate number of results after a certain threshold. The "relation" determines how the "total" should be interpreted. A value of "gte" means that there might be more than the "total" results. When the relation has value of "eq", it indicates that "total" is the exact count. The value of "current" is the total number of results in current page.

Change Page Size

By default, 100 results are returned per query. To get more results, simply add "&page_size=" to your query.

https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&page_size=1000
https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&page_size=5000
https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&page_size=10000

Cost for Single Query = (Additional 1 API Credit for each 100 Results, Max 10000 Results Allowed)

Search Pagination

If the total results are greater than current page size, simply add "&search_after=" to get the next page of results.

https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&search_after=XXXXXXX_XXXXX

Replace "XXXXXXX_XXXXX" with the value you receive for "search_after" at current page.

Change Results Sorting

By default, results are sorted by "query_time" in ascending order. You can change the sorting in the following ways:

https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=query_time&sort_order=asc
https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=query_time&sort_order=desc

https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=create_date&sort_order=asc
https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=create_date&sort_order=desc

https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=update_date&sort_order=asc
https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=update_date&sort_order=desc

https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=expiry_date&sort_order=asc
https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=expiry_date&sort_order=desc

https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=registrar_iana&sort_order=asc
https://api.bigdomaindata.com/?key=XXXXX&database=historical&domain_name=youtube.com&sort_by=registrar_iana&sort_order=desc

Cost for Single Query = (Same as with Default Sorting, No Extra Charges to Change Sorting)
