Changelog

What shipped.

Every release that changes what you can build — in plain English, newest first. Breaking changes are always called out here and in the versioning policy.

APIJuly 12, 2026

Publishable keys, embeddable widgets, hosted MCP

  • Publishable keys (mpk_) — a browser-safe, read-only key type for embedding Muso data in your website. Create and manage them from the console Keys page; they can only read profile data on a dedicated embed surface and can never touch the paid catalog API.
  • Embed surface: GET api.platform.muso.ai/embed/v1/profile/{id} (+ credits, charts, collaborators) with CORS enabled — callable directly from the browser with a publishable key.
  • @muso-ai/embeds — drop-in Profile Card and Roster widgets: a <script> embed for any website and a React component, styled on the Muso design system.
  • Hosted MCP endpoint — mcp.muso.ai now serves the platform Data API over the Model Context Protocol (Streamable HTTP), so AI clients like Claude can use your key without running a local server.
  • muso CLI — a public command-line client (login, profile, credits, search, usage) entered review; install channel announced when it lands.
PricingJuly 10, 2026

Pure pay-as-you-go pricing with usage tiers

  • One metered plan: add a card, start with $5 in credits, pay per call on marginal volume bands — no base fee, no trials, no plans to pick.
  • Usage tiers (Start / Build / Scale) govern throughput and monthly spend caps — the per-call rate is the same at every tier. Tiers grow automatically with usage history, or upgrade instantly with a monthly commitment that credits toward your usage.
  • Per-profile chart analytics (positions, scores, popularity) are available today in the metered API. Platform Analytics ($3,000/mo minimum) — system-wide, cross-catalog analytics with Scale-tier throughput — is rolling out.
  • The console Limits page shows your tier, rate limits, spend cap, and self-service upgrades.
PlatformJuly 9, 2026

The platform site is public

  • platform.muso.ai marketing, pricing, and documentation are publicly reachable (the developer console still requires sign-in).
  • api.platform.muso.ai is live — the dedicated API host documented in every quickstart.
  • The site now runs on the Muso design system (Octave) end-to-end.
SecurityJuly 8, 2026

Legal terms, transactional email, social sign-in

  • Terms of Service and the Data License Agreement published at /legal — including the live-use (no caching/storage) license and the enterprise storage carve-out.
  • Verification, password-reset, and team-invitation emails are delivered (previously log-only).
  • Sign-in with Google, Apple, and Facebook verified end-to-end on login.muso.ai.
PlatformJuly 6, 2026

Self-serve launch surface

  • Sign up with your Muso account (login.muso.ai), add a card, and get a working API key — provisioned at the gateway with metering from the first call.
  • Team workspaces: invite members, roles (owner/admin/member), key visibility gated by role, removal rotates the workspace key.
  • Docs overhauled: real endpoint paths, runnable quickstart, x-api-key auth everywhere, try-it panel wired to the live API.

Current operational state lives on the status page (machine-readable at /api/status).
