What is Suno API AI
Suno Music API is a service that allows users to generate complete songs from prompts or lyrics. It also provides functionalities to extend existing songs, create covers, upload audio, separate stems, edit audio, and export production-ready audio.
How to use Suno API AI
To use Suno API AI, you need to integrate with the TTAPI service. This involves obtaining an API key and using the provided endpoints. The process typically involves sending a POST request to specific endpoints like /suno/v1/music with the necessary parameters in the request body. For example, to generate music, you would send a JSON payload including parameters such as custom, instrumental, mv (model version), and either gpt_description_prompt for inspiration mode or prompt for custom lyrics mode. You can also specify optional parameters like title, tags, negative_tags, style_weight, weirdness_constraint, audio_weight, duration, auto_lyrics, vocal_gender, persona_id, isStorage, and hookUrl for callbacks.
