Examples for using suno-v4.5 through RunAPI from agent tools or API calls. Copy a prompt, then use it in Claude Code, Codex, Cursor, Windsurf, or your backend.
1. claude mcp add runapi -s user -- npx -y @runapi.ai/mcp
2. Restart Claude Code
3. Paste this prompt: Generate music: "A gentle acoustic folk ballad about watching seasons change from a cabin porch. Fingerpicked steel-string acoustic guitar in open D tuning provides the foundation. A soft male vocal with a warm, slightly raspy tone sings verses about morning frost, migrating birds, and the first snow. Light harmonica accents between verses. A subtle cello enters on the final chorus adding emotional depth. Tempo around 85 BPM in 3/4 waltz time. The recording should sound intimate, as if performed in a small wooden room with natural room reverb."

An intense 8-bit chiptune boss battle theme for a retro platformer game. Fast tempo at 160 BPM. The lead melody uses a square wave with rapid pitch bends and arpeggios in E minor. Triangle wave bass plays driving eighth notes outlining power chords. The pulse channel drums deliver aggressive kick-snare patterns with fills every four bars. A brief four-bar breakdown in the middle drops to half speed before exploding back. The composition loops seamlessly. Inspired by NES-era Mega Man and Castlevania soundtracks — urgent, relentless, and catchy despite hardware limitations.

FAQ
Using suno-v4.5 prompts
What is %{model}?
%{model} is available through RunAPI as part of the unified model catalog. These prompts show practical input patterns that agents and backend services can reuse.
How do I use these prompts?
Copy any prompt and paste it into Claude Code, Codex, Cursor, or Windsurf after installing the RunAPI MCP Server. Developers can also copy the API example and send the prompt directly.
Do these prompts cost money to browse?
Browsing and copying prompt examples is free. Generation requests only cost money when you call a RunAPI model with your API key.
Can I adapt the prompts for production?
Yes. Treat each prompt as a starting point, then add your brand rules, output dimensions, safety constraints, and application-specific context before using it in production.
