Bulk Whois API User Guide (old)

Bulk Whois API provides Whois records for a list of Domains/IPs via a single REST API query. It is designed for server-to-server communication between your system and the WhoisXmlApi.com network using standard HTTP or HTTPS protocols. Query responses are delivered in either XML or JSON format based on your requests which are made via POST methods.

To get started you need an account with WhoisXmlApi.com. Authentication is required each time in order to use the API. The first 500 Bulk Whois API calls are complimentary when you register for a free account.

Getting Whois Records

POST https://www.whoisxmlapi.com/BulkWhoisLookup/bulkServices/getRecords

  • 0 - processed;

  • 3 - processing.
