Be specific in your prompt about genre, mood, instrumentation, and pacing.
Mention arrangement cues like intro, build, drop, chorus, or ambient bed when needed.
Start with shorter durations to validate the musical direction before generating longer pieces.
Use concise prompts when you want tighter control, and broader prompts when you want more interpretive results.

duration supports values from 1 to 360 seconds.
Pricing depends only on the selected duration.
Longer generated music may be more suitable for trailers, background scoring, and extended content workflows.

Text To Music API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/sonilo/text-to-music with your input as JSON. The endpoint returns a prediction id; poll the prediction endpoint until status flips to completed, then read the output URL from data.outputs[0]. Examples for Text To Music below.

HTTP example

# Submit the prediction
curl -X POST "https://api.wavespeed.ai/api/v3/sonilo/text-to-music" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY" \
  -d '{
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "duration": 30
}'

# Response includes a prediction id. Poll for the result:
curl -X GET "https://api.wavespeed.ai/api/v3/predictions/{request_id}/result" \
  -H "Authorization: Bearer $WAVESPEED_API_KEY"

# When status is "completed", read the output from data.outputs[0].

Node.js example

// npm install wavespeed
const WaveSpeed = require('wavespeed');

const client = new WaveSpeed(); // reads WAVESPEED_API_KEY from env

const result = await client.run("sonilo/text-to-music", {
        "prompt": "A cinematic shot of a city at sunset, soft golden light",
        "duration": 30
});

console.log(result.outputs[0]); // → URL of the generated output

Python example

# pip install wavespeed
import wavespeed

output = wavespeed.run(
    "sonilo/text-to-music",
    {
    "prompt": "A cinematic shot of a city at sunset, soft golden light",
    "duration": 30
}
)

print(output["outputs"][0])  # → URL of the generated output

Text To Music API — Frequently asked questions

What is the Text To Music API?

Text To Music is a Sonilo model for audio generation, exposed as a REST API on WaveSpeedAI. Sonilo Text-to-Music is a fast AI music generation model that creates full music tracks from text prompts with manual duration control. Ready-to-use REST inference API for AI music generation, background music, creator content, video soundtracks, advertising audio, social media content, and professional text-to-music workflows with simple integration, no coldstarts, and affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Text To Music API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header. Submission returns a prediction ID; poll the prediction endpoint until status flips to "completed", then read the output URL from the result. The playground generates a ready-to-paste code sample in Python, JavaScript, or cURL for whatever inputs you've set. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/sonilo/sonilo-text-to-music.

How much does Text To Music cost per run?

Text To Music starts at $0.003 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Text To Music accept?

Key inputs: `prompt`, `duration`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/sonilo/sonilo-text-to-music.

How do I get started with the Text To Music API?

Sign up for a free WaveSpeedAI account to claim starter credits, copy your API key from /accesskey, then call the endpoint shown in the API tab of the playground. The playground also auto-generates a code sample in Python, JavaScript, or cURL for the parameters you've set.

Can I use Text To Music outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (Sonilo). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
