Many domain name providers offer APIs that allow developers to perform actions such as registering a new domain name, domain renewal, domain availability API, perform WHOIS lookups, and much more.
Domain checker APIs are server-side software hosted at a domain name registrar or a similar company. The software exposes specific endpoints or methods that developers can use to accomplish the goals of their programs.
Developers write programs that send commands to the API as a request. Requests and responses are often in JSON or XML format. Generally, reference documentation is available that explains the correct format and syntax. When the API receives the request, the server processes the request according to the parameters given. Once the processing is complete, the API returns a result to the program so it knows whether the request succeeded or failed and what action to take next.
Domain name APIs are for developers that want to programmatically integrate their software with domain name registries. Examples include businesses that resell domain names and businesses that provide domain search API or WHOIS lookup tools for their customers.
Domain availability APIs allow developers to integrate directly with domain registrars to perform actions that customers want to do. Many domain name resellers make use of such APIs to provide a better customer experience that they might get elsewhere.
Domain check API providers generally provide free documentation for developers that detail all of the available endpoints or methods that developers can use. The developer provided documentation outlines the correct syntax for each request as well as the format and structure of the response. Some domain checker API providers will also provide sample code or demo projects for developers to get started quickly.
