AI Music API (website https://sunoapi.com/）是一款面向应用与开发者的 AI music generation API service, focused on integrating music generation capabilities into various products. The official website describes its positioning as a "fast, cheap, legal" AI music API, with target users being teams that need to generate background music or songs in batches and on demand, such as developers of video editors, game engines, and content apps.
Main capabilities
- Music generation: According to the official website, the service is powered by Sonic and Producer (upgraded from Riffusion) models, and can generate vocals, instrumentals, full songs, and background music tracks, supporting multiple styles and languages. The official page says, "From chill beats to cinematic anthems, any style can be generated."
- Generation speed and quality: The official website says it can generate complete high-quality tracks in about 30 seconds, and says all generated songs are completely clean, watermark-free, and ready to use.
- Commercial licensing: The official website says that through a premium subscription pool, commercial licensing for works can be guaranteed, with pricing starting at $0.08 per generation.
- Suno V6 API: The page mentions that v6, v6-wild, and v6-mini can be used as model IDs for the generation endpoint (the page is dated September 9, 2026), and explains that when Suno released v6 it did not provide an API, and that this service provides a way to call it from code.
- Developer materials: Provides guidance content on prompt and lyrics character limits (style prompts, custom lyrics, and title limits for each model version from V3.5 to V5.5), comparisons of AI music generation APIs, whether Suno has an API, and more; the page says Udio has no public API, Suno's API is only for partners, and says its pricing starts at $0.08.
How to use The workflow described on the official website is asynchronous invocation:
- Submit a request: When a scene, mood, or template is selected, the app calls the create-music endpoint and obtains a task id.
- Handle the asynchronous task: Generation runs in the background and usually takes 1-3 minutes. The app should save the task id and obtain the result by polling the task endpoint or registering a webhook, rather than blocking the request.
- Retrieve the finished audio: After the task succeeds, the response (or webhook payload) contains the final audio URL, which can be directly integrated by a video pipeline. The official website also mentions that you can first use free credits to test the API key, model quality, documentation, and pricing, and then scale to production.
Use cases According to the official website, it is suitable for on-demand generation of video background music, video editors, game engines, and content apps for scene scoring,Creator tools, games, video products, podcast workflows, and SaaS features, etc.
Limitations and information not yet provided The official website does not provide a complete list of specific API endpoints, details of authentication methods, a price tier table for each model, call quota limits, etc.; the above-mentioned price starting at $0.08, 30-second generation, 1–3 minute asynchronous duration, commercial licensing, and model information are all statements made by the official website, and the actual details are subject to the official documentation and terms. Documentation and support outside of Chinese are mainly provided through the Discord community.
