Suno API 是甚麼？
Suno is an AI music generation platform that creates original songs — vocals, instruments, and lyrics — from text descriptions. Through RunAPI, all Suno versions share a single API key with per-call billing.
為何透過 RunAPI 使用 Suno API
一個驗證，對應所有 provider
一組 RunAPI key 即可解鎖整個 catalog。無需分開帳戶，亦無需為每個整合輪換密鑰。
統一定價與計費
按次以 USD 收費，每月結算。失敗的生成不會收費。
內含 schema 的 skill
型別化 schema 與 setup 備註打包在 model skill 內，讓實作從正確契約開始。
常見問題
How long can a generated song be?
v4.5 及 v5+ 每次生成最長 8 分鐘（較早版本最長 4 分鐘）。用 Extend endpoint 串接片段以製作更長嘅曲目。
Can I provide my own lyrics?
Yes — pass lyrics with [Verse], [Chorus], and [Bridge] tags. You can also let Suno write lyrics from a theme prompt.
How long does generation take?
Typically 30–120 seconds per track. Instrumental-only tracks tend to generate faster.
Can I create instrumental-only tracks?
Yes — set the instrumental flag to true and Suno generates a vocal-free track.
What genres are supported?
Any genre — pop, jazz, lo-fi, classical, metal, hip-hop, electronic, and more. Describe the genre in your prompt.
我應該先用邊個版本？
先選最平而且符合你質素要求的版本。大多數團隊會先用快速版本，之後再升級到 pro 用於正式生產。
有免費方案嗎？
新帳戶可獲得每個模型的首次呼叫免費。之後按次收費。
你哋支援串流結果嗎？
如有提供串流，RunAPI 會端到端串流。
失敗會點樣收費？
生成失敗不會收費。
輸出有快取嗎？
已生成輸出會儲存，並可按任務 ID 取回。輸入內容不會快取。
可以商業使用嗎？
可以——除非模型授權明確限制，否則每個版本都包括商業使用。相關限制會在版本頁面列明。
限流點樣計？
每個密鑰的限流會跟使用等級而提升。最新限制請參考定價頁。
可以在邊度報告問題？
可以在公開 GitHub repo 開 issue，或者電郵支援。
