# Using the API There are currently two APIs supported. The current API (referred to in the documentation as API or API 2) is the current API version, and is the default version used for all operations unless otherwise specified. The legacy API v1 is being phased out, but is still used for some conferences (primarily those before 2024) While most operations will work on both APIs, pay careful attention when that is not the case, for example, the JSON format for each API is different. --- # 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.openreview.net/getting-started/using-the-api.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.
