Quickstart

Examples use the selected endpoint’s public parameter definitions. Replace the API key and example media, then send the request from your server.

API authentication

Keep the API key in the server environment variable SPICY_API_KEY. Use Bearer authentication and Content-Type: application/json for JSON requests.

Authorization: Bearer $SPICY_API_KEY
# Generate the idempotency key once; reuse it when retrying after a lost response.
export SPICY_IDEMPOTENCY_KEY="${SPICY_IDEMPOTENCY_KEY:-$(uuidgen)}"
curl -X POST https://api.spicyapi.ai/api/v1/jobs/createTask \

Generated from this model’s input schema — the same one the API validates every request against.

Input parameters

Place these fields inside the request body’s input object. Names and types match the API. Do not assume a default when none is specified.

promptstringRequired

The style brief. With your own lyrics or instrumental on, it is the style only: genre, tempo, instruments, voice, mood, up to 1,000 characters. With no lyrics and generate_lyrics on, it is the idea for the song and the model writes the words from it, up to 3,000 characters. Describe styles in words; prompts that name real artists are refused. Does not change the price.

minLength:1
maxLength:3000
reference_audio_urlsarray<string>Optional

One reference audio file (6 seconds to 30 minutes, up to 500 MB) that inspires the song. Only with generated lyrics: no lyrics, instrumental off, generate_lyrics on. Use audio you have the right to use. Does not change the price.

image_urlsarray<string>Optional

Up to 5 mood images (JPEG, PNG, WebP or BMP, each up to 10 MB) that the model draws on for the feel of the song. Only with generated lyrics: no lyrics, instrumental off, generate_lyrics on. In other modes it returns a clear error. Does not change the price.

Default
Not specified
Constraints
minLength:1
maxLength:200
varietyintegerOptional

How much the model varies your style prompt, as a whole number from 0 (off: your style tags are used exactly as written) to 4 (maximum). Default 1. This is Suno's own description of the setting; we have not tested it. Applies with your own lyrics or instrumental on only. Does not change the price.

Default
Not specified
Constraints
minimum:0

audio_weightnumberOptional

How strongly the input audio shapes the result, from 0 to 1 in steps of 0.01. Suno does not support it for songs without vocals. Applies with your own lyrics or instrumental on only. Does not change the price.

The words to sing, up to 5,000 characters, one line per row. Section tags such as [Verse], [Chorus], [Bridge] and [Outro] on their own rows shape the structure and are not sung.

Track the task

HTTP 202 means the task was accepted, not completed. Save the returned taskId and query that task. Do not create another task while waiting for its result.

Accepted response
HTTP/1.1 202 Accepted
Location: /api/v1/jobs/recordInfo?taskId=job_01k3m8x9q2z4v7n5p6r8s0t1w3

{
  "code": 200,
  "msg": "success",
  "request_id": "req_example_create",
  "data": {
    "taskId": "job_01k3m8x9q2z4v7n5p6r8s0t1w3",
    "state": "queued",
    "estimatedCost": "0.750000"
  }
}

The accepted response includes the estimate so your app can show the same amount in task history and billing.

Read the job
curl --get "https://api.spicyapi.ai/api/v1/jobs/recordInfo" \
  --data-urlencode "taskId=$TASK_ID" \
  -H "Authorization: Bearer $SPICY_API_KEY"

Start polling at about 2 seconds and gradually increase the interval. Stop at a terminal state. After a connection failure, query the original taskId. Retry creation only with the original idempotency key and body.

Or let the callback find you
import { verifyWebhook } from "@spicyapi/sdk";

// express.raw keeps the bytes we signed; express.json never matches.
app.post("/hooks/spicy", express.raw({ type: "application/json" }), (req, res) => {
  const { payload } = verifyWebhook({
    rawBody: req.body,
    timestamp: req.header("X-Webhook-Timestamp"),
    signature: req.header("X-Webhook-Signature"),
    payloadVersion: Number(req.header("X-Webhook-Payload-Version")),
    secret: process.env.SPICY_WEBHOOK_SECRET,
  });
  res.status(200).end();
  void handleFinishedTask(payload);
});

Pass callBackUrl when you create the task and the finished record is POSTed to you — no polling loop at all. Every delivery carries X-Webhook-Timestamp, X-Webhook-Signature and X-Webhook-Payload-Version. The signature is a base64 HMAC-SHA256 over taskId.timestamp.sha256(body), so it must be checked against the raw bytes: parsing the JSON and re-serialising it changes them and the check will fail. Failed deliveries are retried, so the same taskId can arrive twice — make the handler idempotent. Answer 2xx first and do the work afterwards; a slow handler is treated as a failed delivery.

Read the result

Consume output only when state is succeeded. On failure, use errorCode, errorMessage and request_id to investigate. Example costs and states do not represent an actual bill.

  }
}

For each available asset, open or download assets[].url directly without an API Authorization header. The signed URL expires at expiresAt; poll the task again to refresh it while the asset remains within its retention period. A pending or unavailable asset has no URL. Treat signed URLs as private.
