Call the Recoupable API from the sandbox to fetch artist data, socials, organizations, research, documents and any other platform resource — and to invoke external connector actions (Google Docs / Drive / Sheets edits, Gmail, TikTok, Instagram, etc.) via Recoupable's shared connections. Use whenever you're asked for Recoup data, a Recoupable platform resource, or to read/write something outside Recoup like a Google Doc URL or a spreadsheet. Triggers on phrases like "look up artist", "fetch from recoup", "artist data", "artist socials", "organizations", "artist report", "research", "create new artist", "create artist", "onboard artist", "add artist", "edit this Google Doc", "read this doc", "update the spreadsheet", "send an email", "post on TikTok", "save to Drive", or whenever the user pastes a docs.google.com / drive.google.com / sheets.google.com URL. Always load this before writing curl calls against api.recoupable.com.
