OfSpectrum audio watermark and deepfake detection API service Sold on its own

Self-serve API, Python SDK and web dashboard that embed inaudible, edit-resistant watermarks carrying rights and C2PA-compatible provenance data into audio, trace leaks and piracy back to a recipient, and tell AI-generated voices from real ones in real time; billed at $0.50 per hour of audio plus a one-time token fee per unique watermark, with custom quotes for larger use.
