# API Key Management In order to use our EigenAPI Pro service, it is necessary to possess an API key. Once you contact us and subscribe our EigenAPI `Pro Plan`, we will provide you with the API Key. EigenAPI `Pro Plan`service is designed to provide you with the tools and resources needed to take your projects to the next level. Our Pro Plan is tailored to meet the needs of professional users, allowing you to maximize the benefits of our product. You are welcome to [contact us](mailto:contact@eigenphi.com) or visit our [product page](https://eigenapi.io/) to get started. Once you have successfully subscribed to our service, you can easily view your API key on [this page](https://eigenapi.io/apikey). Additionally, you can check the status of your subscription and its expiration date. Currently, all you need to do is contact us and subscribe to our plan, and we will generate an API key for you. In the meantime, We're developing a self-service subscription process and implementing a direct payment method for our customers, and the payment method will be available very soon. Users will be able to subscribe to our service independently, and we will offer flexible payment options such as tokens or other ways to meet your specific needs. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
