Qwen Image 2.1 Turbo image editing changes a picture from a plain-language instruction in 8 denoising steps. Up to ten references, one to six results per request at one flat price, no content filter, and prompt expansion off by default so your instruction is not watered down.
Examples use the selected endpoint’s public parameter definitions. Replace the API key and example media, then send the request from your server.

image_urlsarray<string>RequiredOne to ten source images, in the order you refer to them. The number of references does not change the price. We tested composites with two; check identity yourself when you send many.
promptstringRequiredThe edit instruction, up to 5,000 characters. Say what changes first, then what must stay: face, hair, pose, light. Refer to references as Image 1, Image 2 and so on.
seedintegerOptionalSteadies a draw so you can compare one change at a time. It does not guarantee a pixel-identical image. Keep the returned file when you need that exact frame again.
enable_thinkingbooleanOptionalSpends extra reasoning on the rewrite, at the cost of a longer wait. Only works while prompt expansion is on. Does not change the price.
enable_prompt_expansionbooleanOptionalOff by default. On, Alibaba rewrites the instruction first, and in our tests that rewrite dropped requests to reveal more: the source came back unchanged and was still billed. Leave it off for unfiltered edits. Does not change the price.
num_outputsintegerOptionalAffects priceOne to six results from the same instruction in one request. Each image returned is billed.
resolutionstringOptional1k, 1.5k or 2k, used only when you set an aspect ratio. Every tier costs the same per image.
"1k""1.5k""2k"aspect_ratiostringOptionalLeave it out and the result keeps the shape of your source at about 2K. Set one of fifteen shapes when you want a fixed frame, for example 16:9 for two people side by side.

}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.

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.
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.

Use SpicyAPI in your app, terminal, AI assistant or visual workflow. Choose a setup guide below.
You do not have to write any of the code above. Connect the MCP server once and any agent that speaks MCP — Claude Code, Codex, Cursor, Windsurf, VS Code, Gemini CLI, Cline, LibreChat — can run this model by name, or run it from your shell with a single command.
Use alibaba/qwen-image-2.1-turbo/edit to edit ./poster.png — warmer light, cleaner background — and save the result next to it.
The agent looks the model up in the live catalogue, uploads the local file for you, then shows the exact quote and its maximum charge and waits for your confirmation. Nothing is billed until you say yes.
claude mcp add spicyapi -e SPICY_API_KEY=$SPICY_API_KEY \
-- npx --yes --package=@spicyapi/mcp spicyapi-mcp
npx skills add spicyapi-ai/spicy-skillThe first line gives the agent the tools; the second gives it the Skill — the operating rules for them, so it quotes before it bills, uploads local files instead of pasting bytes, and reads the finished asset URL rather than guessing. Every other client takes the same server through its own config file: see the developer hub.
npx @spicyapi/cli tasks create --model alibaba/qwen-image-2.1-turbo/edit \
--input-json '{"image_urls":["https://example.com/reference.png"],"num_outputs":1,"prompt":"A ceramic teapot on a linen cloth, soft window light, muted palette","resolution":"2k"}' \
--waitThe input is this endpoint’s own schema, same as the examples above. --wait polls until the task is finished and prints it; add --yes to skip the confirmation prompt in CI. Set SPICY_API_KEY first — one key works for the API, the CLI and the MCP server.
npx @spicyapi/cli tasks create --model alibaba/qwen-image-2.1-turbo/edit \
--input-json '{…}' --retention 1h --wait
npx @spicyapi/cli tasks get $TASK_ID # read back the retention that applied--retention only ever shortens the window — 30m, 1h, 7d, or 0 to delete as soon as the task reaches a terminal state. The value that actually applies is the shortest of your request, your account settings and the platform maximum, so read it back from the task record rather than assuming the number you asked for took effect. Passing a longer window than your account allows does nothing.
Install the SpicyAPI nodes from ComfyUI Manager or with the command below, then search for Qwen Image 2.1 Turbo · Image Editing on the canvas. The node has the same options as this page and shows its price before it runs.
cd ComfyUI/custom_nodes
git clone https://github.com/spicyapi-ai/comfyui-spicyapiThe embedded panel reads the same schema as this page, so it cannot drift from the API. If your docs need the content to be searchable, read the JSON under /api/embed/models/ and render it yourself.
