# About the Domain Availability API

The Domain Availability API allows you to check the availability of a specific
domain.

  
## Use cases

+ [Check a domain's availability](https://dev.wix.com/docs/api-reference/account-level/domains/domain-search/sample-flows.md)

## Terminology

+ __Domain__: Domain name including [Top-level domain](https://en.wikipedia.org/wiki/Top-level_domain) (TLD).
+ __Suggestion__: A suggested domain that's available for purchase.
+ __Registered domain__: Domain that's purchased, registered, and billed
  through Wix.
+ __External domain__: Domain that has been purchased through an external
  provider, not Wix. You can use the Connected Domains API to connect external domains to Wix sites.
+ __Account__: Wix account that includes access to associated sites.
  + __Team account__: Account type that supports collaborative work by having
    multiple sets of login credentials. This is especially helpful for agencies
    and resellers when managing a large number of customer sites. In Wix Studio
    team accounts are called workspaces. An agency may have multiple workspaces
    in Wix Studio, while in Wix Editor they're limited to a single team account.
  + __Child account__: Account that's contained within another account, forming a
    hierarchical structure. The owners of the child account are only able to
    interact with sites that belong to the child account. This setup is
    particularly useful for agencies and resellers since it limits client access
    to relevant sites only.
