Suno API Python SDK for RunAPI

The Suno Python SDK is the language-specific package for Suno on RunAPI. Use this package for song generation, lyrics, vocals, extension, and audio transformation workflows when your application needs request bodies, task status lookup, and consistent RunAPI errors in Python.

This README is the Python package guide inside the public suno-sdk repository. For the repository overview, start at ../README.md; for model details, use https://runapi.ai/models/suno; for API reference, use https://runapi.ai/docs/api/suno/text-to-music; for SDK docs, use https://runapi.ai/docs/resources/sdks.

Install

pip install runapi-suno

Quick start

from runapi.suno import SunoClient

client = SunoClient()  # reads RUNAPI_API_KEY, or pass api_key="sk-..."

# Generate music and poll until completion.
result = client.text_to_music.run(
    model="suno-v4.5-plus",
    vocal_mode="auto_lyrics",
    prompt="A chill lo-fi beat with soft vocals",
)
print(result.audios[0].audio_url)

# Generate lyrics from a prompt.
lyrics = client.generate_lyrics.run(prompt="a song about the ocean at night")
print(lyrics.lyrics[0].text)

blended = client.blend_lyrics.run(
    lyrics_a="[Verse]\nCity lights fade into dawn",
    lyrics_b="[Chorus]\nWe rise with the morning sun",
)
print(blended.lyrics[0].text)

Use create to submit a task and return quickly, get to fetch the latest task state, and run when a script should create and poll until completion:

task = client.text_to_music.create(
    model="suno-v4.5-plus",
    vocal_mode="instrumental",
    style="ambient piano",
    title="Quiet Morning",
)
status = client.text_to_music.get(task.id)

In web request handlers, prefer create plus webhook or later get polling so a worker is not held open.

RunAPI-generated file URLs are temporary. Download and store generated images, videos, audio, or other files in your own durable storage within 7 days; do not treat returned URLs as long-term assets.

Language notes

Pass parameters as keyword arguments and catch the runapi.suno error classes when building music jobs or scripts. The available resources are text_to_music, extend_music, generate_artwork, cover_audio, add_instrumental, add_vocals, separate_audio_stems, generate_midi, convert_audio, visualize_music, generate_lyrics, blend_lyrics, get_timestamped_lyrics, replace_section, create_mashup, text_to_sound, voice_to_validation_phrase, regenerate_validation_phrase, generate_voice, check_voice, generate_persona, and boost_style. Keep RUNAPI_API_KEY in the environment or your secret manager; never commit API keys or callback secrets.
