Quickstart

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

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

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.

This model has dependencies between fields. Fields marked conditionally required depend on other inputs; see the complete JSON Schema below for the rules.

seedintegerOptional

0 to 2147483647. Hold it steady to compare one changed field at a time; drop it for variety.

Default
Not specified
Constraints
minimum:0
maximum:2147483647
enable_prompt_expansionbooleanOptional

Off by default. When on, the prompt is rewritten before generation, which helps thin briefs and fights you on detailed ones. If you leave it unset and attach reference_file_url or reference_link_url, it is switched on for that request, because the document or page is read in this step. Set it to false explicitly and the file or page is still read, without the prompt rewrite.

Default
Not specified
generate_audiobooleanOptional

On by default. The clip comes back with sound already locked to the picture. Set false when you are scoring the shot yourself.

Default
true
duration_secondsintegerOptionalAffects price

Any whole number from 2 to 30, or -1 for smart duration. Defaults to 5. With reference videos, their total length plus this value must stay within 30 seconds, and those seconds are billed on top of the output. Settle the look at 5 seconds before extending.

Default
5
Allowed values
-123456789101112131415161718192021222324252627282930
resolutionstringOptionalAffects price

480p, 720p or 1080p. Defaults to 720p. Resolution changes both the price and how long the task takes to come back.

Default
"720p"
Allowed values
"480p""720p""1080p"
enable_thinkingbooleanOptional

Has the model think through the brief and any reference material before generating. It helps with dense documents, web pages and complex reference images, and makes the run slower. Off by default; it switches on automatically when you pass a reference file or link. It does not change the price.

Default
false
aspect_ratiostringOptional

16:9, 9:16, 1:1, 4:3, 3:4 or adaptive, which lets the model choose. Defaults to 16:9.

Default
"16:9"
Allowed values
"16:9""9:16""1:1""4:3""3:4""adaptive"
reference_link_urlstringConditionally required

One public web page the model reads for reference, such as an article, a product page or a character profile. It must open without a login. Some sites refuse automated readers, and a page with too little text cannot be used; in both cases the task fails with a message saying the URL could not be read, and failed tasks are not charged. Not together with reference_file_url; if enable_prompt_expansion is left unset, attaching a link also switches it on. Links are not billed.

Default
Not specified
Constraints
format:"uri"
reference_file_urlstringConditionally required

One document the model reads before it directs the shot: a character sheet, a script, a shot list or a product brief. PDF, DOCX, DOC, TXT, MD, PPTX, PPT, XLSX, XLS, KEY, PAGES or NUMBERS, up to 100 MB and 50 pages. It works on its own or next to reference images, video and audio, but not together with reference_link_url. If enable_prompt_expansion is left unset, attaching a file switches it on for that request, because the document is read through that step. Files are not billed.

reference_audio_urlsarray<string>Conditionally required

Up to 5 clips, each 1 to 15 seconds and 15 seconds in total — a voice, a line reading or room tone the shot has to match. Reference audio is not billed. WAV or MP3, 15 MB per clip. Like the video limits, these are enforced during generation rather than when the task is accepted.

Default
Not specified
Constraints
minItems:1
maxItems:5
reference_video_urlsarray<string>Conditionally requiredAffects price

Up to 5 clips, each 1 to 15 seconds and 15 seconds in total. Use them for movement and camera style rather than for a face. Their length is billed together with the output, and reference video plus output must stay within 30 seconds. MP4 or MOV, at least 16 fps, 240 to 4096 px per side, aspect ratio no wider than 8:1, 100 MB per clip. These limits are enforced during generation rather than when the task is accepted, so check clip lengths before you submit.

Default
Not specified
Constraints
minItems:1
maxItems:5
reference_image_urlsarray<string>Conditionally required

1 to 10 images for identity, wardrobe and set plates. Name each one in the prompt — character, garment, set — or they are averaged together. Reference images are not billed. JPEG, PNG without transparency, BMP or WEBP; 240 to 8000 px per side, aspect ratio no wider than 8:1, 20 MB each.

Default
Not specified
Constraints
minItems:1
maxItems:10
promptstringOptional

Optional. When you write one, name what each reference controls, then the shot: subject, one action, one camera move, light and sound. One clear action moves the result more than a long list of adjectives.

Default
Not specified
Constraints

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.
