Apier.no Actions API
Withdrawn (2026-10-21). The filing-action surface (`POST /api/v1/actions/execute` in dry-run and live mode, the pending-action approve / reject / status routes) answers HTTP 410 `CAPABILITY_WITHDRAWN`: the dry run read Altinn delegation state and the live leg is the parked MVA submission line. Paths and schemas stay published (append-only contract).
