The Moz API is a powerful tool for users who want to analyze the search landscape, build custom dashboards or SEO reporting scripts, enrich their own SaaS applications (with proper attribution), and much more.

Currently, the Moz API is being upgraded to a better and more robust version, which means that many methods are in V3, and some are only available via the legacy version (Moz API V2).

Authentication with the new Moz API V3 is easier than ever. For more information on accessing the Moz API V3 endpoints, be sure to check out the Getting Started section of the updated API Documentation Hub. 

V3 of the Moz API will provide you with more data solutions to help you make informed SEO decisions. With expanded methods and a revamped JSON-RPC format, you can expect a more intuitive API design, simplified authentication, and a better overall developer experience.

In addition to the link data available via V2, Moz API V3 will offer a rich collection of data for keyword and site research through the new methods now available. Be sure to check out our flexible subscription options to find a data solution that fits your project needs. These affordable plans allow for scalability and growth, making the Moz API accessible for any budget size.

Unlike an HTTP REST API, the Moz API V3 exposes a single URL that accepts remote procedure calls. Therefore, we don't talk about "endpoints" in for V3 (a distinct URL + HTTP method that corresponds with some action on a resource), but rather "methods" (the name of the function to be executed by the API server). The method name is passed in the body of the request to the API URL, as per the JSON-RPC 2.0 spec. For developers who are more familiar with HTTP REST patterns, you can think of the Moz API methods as playing a similar role to HTTP endpoints.
