"description": "Paste is a free alternative to Pastebin and GitHub Gist. Every paste is unlisted: anyone with its link can read it, and nobody can list or search pastes. Creating a paste returns an ownerKey; send it in the x-owner-key header to edit or delete the paste. Pastes encrypted in the web app (with a password or a key in the link) hold only scrambled text and cannot be read through the API. Errors are JSON with a plain error sentence.
