Use case

Free Music API

Developers evaluating a music API who want to run real generations and prove it works before spending anything.

The problem

Evaluating a generation API is hard when the trial is a watermarked demo or a credit card is required before the first call. You cannot justify a budget or a procurement step until you have proven the output is good enough, but you cannot prove that without running real generations first.

Why MusicAPI fits this

New accounts get free credits and can run real, full-quality generations with no credit card, not a watermarked or truncated demo.

The free path uses the exact same endpoint, parameters, and output as paid usage, so what you build while evaluating is what ships.

After the free credits, it is pay-as-you-go at one flat per-credit rate. There is no forced monthly minimum just to keep testing.

Code sample

A real request against the live API: start a job, then poll the task endpoint until the audio is ready.

curl

# Run a real generation on free signup credits
# 1. Start a generation job
curl -X POST https://api.musicapi.ai/api/v1/sonic/create \
  -H "Authorization: Bearer $MUSICAPI_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "custom_mode": true,
    "mv": "sonic-v5",
    "prompt": "[Verse] First light on a brand new page [Chorus] We just started, give it a stage",
    "tags": "indie pop, bright, upbeat",
    "title": "First Run",
    "make_instrumental": false
  }'

# Response: { "message": "success", "task_id": "a1b2c3d4-..." }

# 2. Poll until the audio is ready (state: "succeeded")
curl https://api.musicapi.ai/api/v1/sonic/task/a1b2c3d4-... \
  -H "Authorization: Bearer $MUSICAPI_KEY"

# Response data[].audio_url is a ready-to-stream MP3 once state is "succeeded".

FAQ

Is it really free to start?

Yes. New accounts get free credits to run real generations with no credit card. Once the free credits are used you choose a credit pack or a subscription. The current free-credit amount is on the pricing page.

Are free generations watermarked or lower quality?

No. Free-credit generations use the same API and produce the same quality output as paid generations. They simply draw down the free balance. There is no watermark and no truncation.

Do I need a subscription to keep using it?

No. Pay-as-you-go credit packs work with no subscription. Subscriptions are optional for predictable monthly cost, and the per-credit rate is the same either way. See the pricing page for current options.
