# Jewelry Modeling > Generate realistic jewelry-on-model product photos from your jewelry reference images and an optional model photo. ## Overview - **Endpoint**: `https://queue.modelrunner.run/modelrunner/jewelry-modeling` - **Wrapper ID**: `modelrunner/jewelry-modeling` - **Category**: image-to-image - **Kind**: wrapper inference - **Tags**: jewelry, on-model, modeling, e-commerce, product-photography ## Pricing - **Estimated Price**: $0.039 average per output ## Request Lifecycle This wrapper runs on the ModelRunner **asynchronous queue API** — a single POST does not return the output. Every call requires an `Authorization: Key $MODEL_RUNNER_KEY` header. Run three steps: 1. **Submit** — `POST https://queue.modelrunner.run/modelrunner/jewelry-modeling` with a JSON body holding the input fields at the top level. The body may also include a reserved top-level `metadata` object — a flat string map (max 16 keys, key ≤64 / value ≤512 chars) stored on the request for your own tagging. It is never sent to the wrapper; filter your request history with `GET https://queue.modelrunner.run/requests?metadata=` (exact key=value matches, AND-ed). The response carries request handles only (no output yet): ```json { "status": "IN_QUEUE", "request_id": "<21-char id>", "status_url": "https://queue.modelrunner.run/modelrunner/jewelry-modeling/requests//status", "response_url": "https://queue.modelrunner.run/modelrunner/jewelry-modeling/requests/", "cancel_url": "https://queue.modelrunner.run/modelrunner/jewelry-modeling/requests//cancel" } ``` 2. **Poll status** — `GET ` until `status` is `COMPLETED`. Possible values are `IN_QUEUE`, `IN_PROGRESS`, `COMPLETED`, `FAILED`, `CANCELLED`. A `FAILED` request responds with HTTP 400 and an `error` field. 3. **Read result** — `GET `. Returns the finished request, including the generated `output`: ```json { "id": "", "status": "COMPLETED", "output": ..., "input": ... } ``` The JavaScript and Python SDKs below perform steps 2–3 for you. In any language without an SDK (Swift, Go, Kotlin, etc.) you must implement the polling loop and the final result fetch yourself — see the cURL example for the full flow. ### Input Schema - **`prompt`** (`string`, _optional_): Optional additional prompt to refine the jewelry modeling result. - **`image_size`** (`image_size_enum`, _optional_): The size of the generated image. - Default: `"1_1_1k"` - Options: `"1_1_512"`, `"1_1_1k"`, `"1_1_2k"`, `"1_1_4k"`, `"16_9_512"`, `"16_9_1k"`, `"16_9_2k"`, `"16_9_4k"`, `"9_16_512"`, `"9_16_1k"`, `"9_16_2k"`, `"9_16_4k"`, `"4_3_512"`, `"4_3_1k"`, `"4_3_2k"`, `"4_3_4k"`, `"3_4_512"`, `"3_4_1k"`, `"3_4_2k"`, `"3_4_4k"`, `"3_2_512"`, `"3_2_1k"`, `"3_2_2k"`, `"3_2_4k"`, `"2_3_512"`, `"2_3_1k"`, `"2_3_2k"`, `"2_3_4k"`, `"21_9_512"`, `"21_9_1k"`, `"21_9_2k"`, `"21_9_4k"` - **`model_image`** (`string`, _optional_): Optional model/person reference image for jewelry modeling. Supports public URLs or data URIs. - **`num_outputs`** (`integer`, _optional_): The number of images to generate. - Default: `1` - Range: `1` to `4` - **`jewelry_images`** (`array`, _required_): Jewelry image(s) for jewelry modeling. List of 1-2 images. Supports public URLs or data URIs. ### Output Schema _No `Output` schema properties are available._ ## Default Example **Output** ```json "YStxdu0uJIab8AugBSvaJ" ``` ## Usage Examples ### cURL The queue API is asynchronous: submit the request, poll `status_url` until it is `COMPLETED`, then read the result from `response_url`. Requires `jq`. ```bash # 1. Submit the request (returns request handles, not the output) SUBMIT=$(curl --silent --request POST \ --url https://queue.modelrunner.run/modelrunner/jewelry-modeling \ --header "Authorization: Key $MODEL_RUNNER_KEY" \ --header "Content-Type: application/json" \ --data '{ "jewelry_images": [] }') STATUS_URL=$(echo "$SUBMIT" | jq -r '.status_url') RESPONSE_URL=$(echo "$SUBMIT" | jq -r '.response_url') # 2. Poll until the request leaves the queue / in-progress state while true; do STATUS=$(curl --silent --url "$STATUS_URL" \ --header "Authorization: Key $MODEL_RUNNER_KEY" | jq -r '.status') echo "Status: $STATUS" case "$STATUS" in COMPLETED) break ;; FAILED|CANCELLED) echo "Request $STATUS"; exit 1 ;; esac sleep 1 done # 3. Read the finished request, including the generated output curl --silent --url "$RESPONSE_URL" \ --header "Authorization: Key $MODEL_RUNNER_KEY" ``` ### JavaScript ```javascript import { modelrunner } from "@modelrunner/client"; const result = await modelrunner.subscribe("modelrunner/jewelry-modeling", { input: { "jewelry_images": [] } }); console.log(result.data); ``` ### Python ```python import asyncio import modelrunner_ai async def main(): response = await modelrunner_ai.submit_async( "modelrunner/jewelry-modeling", arguments={ "jewelry_images": [] } ) result = await response.get() print(result["output"]) asyncio.run(main()) ``` ## Additional Resources - [Playground](https://modelrunner.ai/wrappers/modelrunner/jewelry-modeling) - [OpenAPI Schema](https://modelrunner.ai/wrappers/modelrunner/jewelry-modeling/openapi.json) - [LLM Instructions](https://modelrunner.ai/wrappers/modelrunner/jewelry-modeling/llms.txt)
