About

ONCE is a music distribution agent. It takes a release — audio, cover art, and metadata — validates it against store requirements, delivers it to Spotify, Apple Music, and every other major streaming platform, and reports streams and royalties back. This A2A interface serves public reference data; submitting a release runs over the OAuth-protected MCP server or REST API.

Use cases: audio-video, finance-accounting
