Song Generation API vs Udio

Comparing song generation API vs Udio: Udio is a consumer subscription app with no public developer endpoint. PixelAPI is a pay-per-call REST API — POST your lyrics and a style prompt, get back an MP3 in seconds. $0.028 per song. No subscription, no seat limits, 300 free credits to start, no credit card required.

Quick start — one API call

Sign up, copy your key from the dashboard, and POST your song request. For short durations the MP3 is often returned inline. For longer tracks, poll until status=completed and download from output_url.

curl -X POST https://api.pixelapi.dev/v1/song/generate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "upbeat indie pop, acoustic guitar, warm vocals",
    "lyrics": "[Verse]\nSunshine through the window pane\nEverything is new again\n[Chorus]\nSing it out, we are alive",
    "duration": 60,
    "language": "en"
  }'
# Response: {"generation_id": "uuid", "status": "processing", ...}

# Poll until completed
curl https://api.pixelapi.dev/v1/song/UUID \

# Response: {"status": "completed", "output_url": "https://..."}

Integrations & SDKs

Comparison vs alternatives

Rate limits & error handling

Free trial: 20 requests/minute, 3 concurrent jobs. Starter: 60 req/min, 10 concurrent. Pro: 120 req/min, 20 concurrent. Scale: 300 req/min, 50 concurrent. Full details at pixelapi.dev/docs/parallel-processing.html.

Exceeding the rate limit returns HTTP 429 with a Retry-After header. The recommended strategy is exponential backoff starting at 2 s and doubling up to 30 s. The Python and Node SDKs handle this automatically.

# Python SDK — auto-retries 429 with exponential backoff
from pixelapi import PixelAPI
client = PixelAPI(api_key="...", max_retries=4)
result = client.generate_song(
    prompt="chill lo-fi hip hop",
    lyrics="[Verse]\nLate night study session",
    duration=90,
)  # auto-retries on 429, raises after max_retries exhausted

If a generation fails (bad prompt, content policy), the job is rejected and the 28 credits are automatically refunded — you never pay for a failed result.
