Verifalia provides an email verification API (Application Programming Interface) that allows the validation of email addresses, retrieval of historical data and statistics, credit management, and more. The API is accessible as a secure RESTful web service, using JSON as its primary data exchange format.
The Verifalia API is compatible with any platform or language capable of performing HTTP requests, such as cURL and wget. Additionally, we offer free and open-source SDKs, simplifying email address checks with a one-liner in some of the most popular development platforms.
What is a RESTful API?
A RESTful API (Representational State Transfer) is an architectural style for designing networked applications: it applies a set of constraints to web services, defining their communication over the Hypertext Transfer Protocol (HTTP) and access to a set of URLs. In Verifalia, content accessed at these locations is typically returned as JSON (refer to the API documentation for specific resources allowing the exchange of other content types). Resources often have one or more HTTP methods, such as GET, POST, PUT, and DELETE. RESTful APIs are widely used in web service development for their simplicity, scalability, and statelessness.
Which SDKs are available?
While it is feasible to utilize the Verifalia API without a specific helper library, we provide free and open-source SDKs to streamline the integration of our email checker into various applications.
These SDKs are accessible for a range of development platforms and languages.
