Tracks without an ISRC receive a sequential PENNY house ISRC automatically at finalize. Free until the window closes; no exclusivity; the creator keeps all rights. Returns releaseId and live status.

Use it as X-Api-Key against /api/v1/b2b-ingest/* or hand it to a human for https://penny-labels.web.app/fastpass/. Minting or using a key constitutes acceptance of the PENNY Delivery Terms (https://pennyhq.com/delivery/terms/): non-exclusive grant, $0.01/stream with 71% to the rights holder, monthly reports, net-30 payment, 2-business-day takedowns.
