# Additional APIs Let's expands on the main Paymento Gateway API Documentation to cover additional APIs that you may find useful for managing your online store's payment processing capabilities. These APIs provide functionality for retrieving a list of accepted cryptocurrencies and configuring payment settings, including callback URLs and HTTP methods for callbacks. --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.paymento.io/api-documention/additional-apis.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
