minimax/h3-spicy/image-to-video

MiniMax H3 Spicy image-to-video is an uncensored LoRA build of MiniMax H3 that animates the opening frame you supply. Add an optional closing frame and prompt for a clip of 3 to 15 seconds at 480p, 540p, 768p or 1080p.

Send a request

Quickstart

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

SDKs & integrations
POSThttps://api.spicyapi.ai/api/v1/jobs/createTask

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)}"

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.

image_urlstringRequired

Required. The still that animates - it decides the content, so make it right first.

Default
Not specified
Constraints
contentMediaType:["image/jpeg","image/png","image/webp","image/gif"]
seedintegerOptional

Optional, 0 to 2147483647. Keep one seed while you change a single field, such as the prompt or the duration, so the comparison is fair; the same seed does not promise an identical clip. Leave it empty for a fresh take each time. Does not change the price.

Default
Not specified
Constraints
minimum:0
maximum:2147483647
resolutionstringOptionalAffects price

480p, 540p, 768p or 1080p. It defaults to 480p, the cheapest of the four tiers. 768p is the model's native canvas; 1080p is rendered above it, so it is enlarged rather than natively sharper. The tier you pick sets the rate as well as the picture, so draft at 480p and step up for anything you intend to deliver.

Default
"480p"
Allowed values
"480p""540p""768p""1080p"
duration_secondsintegerOptionalAffects price

Whole seconds, 3 to 15. Three is cheap enough to generate variants in bulk.

Default
5
Constraints
minimum:3
maximum:15
promptstringOptional

Optional. Describe the beat, the camera and the sound; do not re-describe the frame.

Default
Not specified
last_image_urlstringOptional

Optional, and only valid with image_url. It pins the ending, not the motion in between.

Default
Not specified
Constraints
contentMediaType:["image/jpeg","image/png","image/webp","image/gif"]

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.

    "completedAt": "2026-08-28T12:00:30Z"
  }
}

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.
