The request asks what to use for a Users API, with no specific product named and no platform constraint given. The closest matches are products whose sources expose user listing or lookup operations: Docusign's REST API lists and adds account users 1, Stack Exchange's API returns and fetches users on a site 4, Instagram's API gets and searches users 5, Notion's API and workspace tools list users 3, and Medium's unofficial API fetches user profiles 9. Choose based on which service's use
A question back: Which service's users do you need the API for (for example Docusign accounts, Notion workspace members, or Stack Exchange site users), so I can narrow this down?
