iZotope Commerce Agent API (UCP / MCP)
iZotope's agent-facing commerce API — an anonymous JSON-RPC 2.0 Model Context Protocol endpoint served on iZotope's own host implementing the Universal Commerce Protocol 2026-04-08. Thirteen tools cover catalog search and lookup, product detail, cart create/read/update/cancel, checkout create/read/update/complete/cancel, and order read. Every tool carries a real JSON Schema 2020-12 inputSchema; every call must identify the calling agent via meta.ucp-agent.profile; complete_checkout requires meta.idempotency-key and, per iZotope's own published rules, explicit contemporaneous buyer approval. Discoverable from /llms.txt, /agents.md and /.well-known/ucp. No key, no account, no plan.
