OnChain Music API review
A free-to-search music API with AI queries and per-track licensing from 5 USDC.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OnChain Music API provides a public REST API and MCP server for finding and licensing music. It is aimed at developers, AI agents and automated creative workflows that need to search tracks, retrieve previews and obtain license documents or download links. Catalog search is free and requires no API key or account. Structured filters include genre, BPM, key, instrumental and keywords, while a natural-language endpoint supports AI-driven queries. The product focuses on music rather than a broader mix of stock media.
Licensing is priced per track. The Social Media License costs 5 USDC and covers non-commercial use on TikTok, Instagram Reels, non-monetized YouTube, X/Twitter and Facebook. The All Digital License costs 35 USDC and covers commercial digital use for advertising, apps, games, podcasts, websites, streaming and commercial YouTube. Both are perpetual, non-exclusive and worldwide. Payments use USDC on Base; after payment, license endpoints issue signed documents and download URLs for available audio formats. This model suits buyers who prefer to pay for individual tracks, though the two licenses differ materially in permitted use.
The API and MCP options make the service relevant to workflows that connect catalog search with AI tools. Its MCP server includes tools for catalog search and music knowledge, and the offering includes an OpenAPI specification and agent discovery manifest. Integrations include MCP clients, Claude, ChatGPT and Cursor. Choose it when an automated workflow needs music discovery and track-level licensing; it is less suitable for buyers seeking other asset types or a single license that covers both social and commercial use. The stated catalog contains thousands of cleared tracks, but this API is described as unproven, so buyers should weigh that qualification when relying on it in production workflows.
