Pastebin

About Pastebin

Pastebin provides a developer API for programmatically creating, listing, retrieving, and deleting text pastes. Requests are made via POST to an endpoint (api_post.php) using a developer API key obtained by registering a Pastebin account; core paste creation requires only the API key, an option flag, and the paste text itself.

The API supports optional parameters for paste title, visibility (public, unlisted, or private), expiration date, folder placement, and syntax-highlighting format, with over 200 supported language/format values. A separate api_user_key parameter, obtained through a member login flow, allows pastes to be associated with a registered user account rather than created as a guest; without it, a guest paste is created.

Additional endpoints allow retrieving a user's paste listing and account settings, deleting a user's pastes, and fetching raw output for both private pastes (owned by the authenticated user) and public/unlisted pastes generally. Free accounts are subject to limits, including a maximum of 25 unlisted and 10 private pastes. The documentation targets developers integrating paste creation and management into external applications or tools.
