Zone Check offers a rapid, preliminary check for domain availability by leveraging cached zone file data. Ideal for large-batch queries, it provides a high confidence indication of a domain’s availability significantly faster than live registry checks. For definitive, real-time availability and pricing, you can follow up with the standard Check Availability call.
The API first validates each submitted domain. Invalid domains are filtered out, and their count is returned in the removed field of the response. If no valid domains remain after this process, the API returns a 400 Bad Request response.
Note: The cached zone files used for this check are refreshed twice daily based on the latest available data from the registries.
Authenticate via HTTP Basic with your account username and API token. Examples use an explicit 'Authorization: Basic <base64(username:token)>' header; 'curl -u username:token' is equivalent. For sandbox, append "-test" to your username and use your sandbox token on api.dev.name.com.
