REST API - ScreenCrafter

Base URL: https://api.screencrafter.io Auth: X-API-Key: sc_live_… (or sc_session cookie from studio). Anonymous sc_anon / scweb- keys work on some REST capture routes and are rejected on MCP. MCP is POST /api/v1/mcp. It can read the balance and spend. It cannot start Stripe Checkout. Purchase is this REST API (and, for humans, the studio Buy credits page).
