# AI Face Reshape # Overview The AI Face Reshape API lets you programmatically reshape facial features — eyes, nose, lips, jawline, or the whole face — with pixel‑perfect control. Use it to generate before/after visualisations for rhinoplasty, chin fillers, lip augmentations, brow lifts and any other aesthetic‑treatment workflow. * Rhinoplasty (Nose Job) Our online rhinoplasty simulator offers medical-grade precision adjustments. Unlike generic photo editing apps, it allows for comprehensive simulation of specific details, including the Bridge, Lift, and Wing. With our hyper-realistic previews, clients can clearly visualize and explore their ideal proportions before consulting. * Chin Filler Through our online simulator, you can preview the ideal proportions achieved with chin fillers. Fine-tune Chin Length and Chin Shape to visualize improvements for a receding or short chin. Discover the optimal solution to balance your facial profile before undergoing any dermal filler treatments. * Lip Filler Users can experiment with different volumes and shapes of lip fillers to simulate the appearance of fuller lips, helping them decide on the desired outcome before undergoing the procedure. * Brow Lift Surgery This functionality enables users to preview the results of a brow lift, which involves lifting and reshaping the eyebrows to create a more youthful and rejuvenated appearance. ## Integration Guide This guide walks you through: Workflow for AI Face Reshape API: **Endpoint:** `/s2s/v2.0/file/face-reshape` **Authentication Required:** `Authorization: Bearer YOUR_API_KEY` **Workflow Steps:** 1. **Image Upload Preparation:** - The process begins with preparing a selfie image. 1. **Optional Preprocessing For Multiple Faces:** - Preprocess the selfie image if there are more than one face in the image. 2. **Face Reshape Effect Setup:** - Begin by selecting suitable face reshape parameters of Eye, Face, Lip or Nose. 3. **Initiate AI Task and Obtain Task ID:** - Send the uploaded image(s) along with the chosen effect configuration via an HTTP POST request to `/s2s/v2.0/file/face-reshape`. - Await a unique task ID in the response, which identifies this interaction. 4. **Poll Task Status (Continuous Check):** - Use the obtained `task_id` to periodically poll the task status using an HTTP GET request (e.g., `GET /task/${task_id}`). - Continuously monitor for: - `Task_status = "success"` (process completed). - `Task_status = "error"` (resolve or retry if applicable). - Update the workflow accordingly once the status transitions to success. This structured workflow ensures efficient integration with user inputs, automated monitoring of tasks, and seamless retrieval of results. --- * API Playground Interactively explore and test the API using our official playground: **API Playground:** [http://yce.makeupar.com/api-console/en/api-playground/ai-face-reshape/](http://yce.makeupar.com/api-console/en/api-playground/ai-face-reshape/) --- * Authentication - Include your API key in the request header using **Bearer Token**: ``` Authorization: Bearer YOUR_API_KEY ``` You can find your API Key at https://yce.makeupar.com/api-console/en/api-keys/. * 1. Upload an Image You may upload a file directly to the server or provide a valid image URL in the AI task payload. * Upload Endpoint ``` POST /s2s/v2.0/file/face-reshape ``` Alternatively, skip this step if you already have a public image URL. --- * 2. Prepare an effect template * Preprocessing Output detected bounding boxes in pixel coordinate. Use the index of result to create a Face Reshape AI task later. ``` { "timed": number, "result": [ { "left": number, "top": number, "width": number, "height": number } ] } ``` * Effect Template JSON Schemas ``` { "version": "1.0", "index": 0, "features": {}, "global": { "skin_smooth_strength": 50, "skin_smooth_color_intensity": 50, }, } ``` index: index of detected face from preprocessing. optional, default 0. features: required at least 1, non-zero face reshape parameter, cannot be all zero. skin_smooth_strength: 0~100 skin_smooth_color_intensity: 0~100 * Effect Format - Face default range: -100~100 range of cheekbones and jaws: 0~100 all feature values must not be zero at the same time, at least one feature value must be non-zero ``` { "cheekbones": 0, "jaw": 0, "face_reshape_left": 0, "face_reshape_right": 0, "face_width": 0, "chin_reshape_left": 0, "chin_reshape_right": 0, "chin_length": 0, } ``` - Eye default range: -100~100 all feature values must not be zero at the same time, at least one feature value must be non-zero ``` { "eye_size_left": 0, "eye_size_right": 0, "eye_distance": 0, "eye_angle": 0, "eye_height": 0, "eye_width": 0, } ``` - Nose default range: -100~100 all feature values must not be zero at the same time, at least one feature value must be non-zero ``` { "nose_bridge_width": 0, "nose_lift": 0, "nose_size": 0, "nose_tip": 0, "nose_tip_width": 0, "nose_wing": 0 } ``` - Lip default range: -100~100 all feature values must not be zero at the same time, at least one feature value must be non-zero ``` { "lip_size": 0, "lip_width": 0, "lip_peak": 0, "lip_height_top": 0, "lip_height_bottom": 0, } ``` * Example Payload (ready to send) ``` { "src_file_url": "https://plugins-media.makeupar.com/strapi/assets/face_reshape_01_85c8ffc055.jpg", "version": "1.0", "source": "yco", "features": { "eye_size_left": 80, "eye_size_right": 80, "eye_width": 0, "eye_height": 0, "eye_distance": 0, "eye_angle": 0, "face_reshape_left": 0, "face_reshape_right": 0, "chin_reshape_left": 20, "chin_reshape_right": 20, "chin_length": 0, "face_width": -30, "cheekbones": 0, "jaw": 0, "lip_size": 10, "lip_width": 40, "lip_height_top": 10, "lip_height_bottom": 10, "lip_peak": -10, "nose_size": 30, "nose_lift": -20, "nose_bridge_width": 10, "nose_tip": -10, "nose_wing": 30, "nose_tip_width": 30 }, "global": { "skin_smooth_strength": 50, "skin_smooth_color_intensity": 50 } } ``` * 3. Create a Face Reshape AI Task and Poll for Results Once you have an image and a complete effect payload, create a task. The API processes the request asynchronously. You must poll the task status until it reaches `success` or `error`. * Create Task Endpoint ``` POST /s2s/v2.0/task/face-reshape ``` * Polling Endpoint ``` GET /s2s/v2.0/task/face-reshape/{task_id} ``` --- ## File Specs & Errors * AI Face Reshape Specification **Supported Selfie View** A selfie with width and height of a face larger than 1/20 of image width and heigh. Face angle less than 30 degree for pitch, yaw and rolling. ![](https://plugins-media.makeupar.com/strapi/assets/thumbnail_face_reshape_01_85c8ffc055.jpg) **Facial Customization Parameters Guide** | Category | Parameter | Function | Min (-100 / 0) | Max (100) | | -------- | ---------------- | ------------------------------------ | -------------- | ------------ | | Eyes | Size (L/R) | Scales overall size of each eye | Small | Large | | Eyes | Width | Adjusts horizontal span | Narrow | Wide | | Eyes | Height | Adjusts vertical span | Narrow / Flat | Round / Tall | | Eyes | Distance | Adjusts spacing between eyes | Close-set | Wide-set | | Eyes | Angle | Adjusts rotational tilt | Inward tilt | Outward tilt | | Face | Size (L/R) | Scales size of each side of the face | Small | Large | | Face | Chin Shape (L/R) | Adjusts chin contour width | Narrow | Wide | | Face | Chin Length | Adjusts vertical chin length | Short | Long | | Face | Width | Adjusts overall facial width | Narrow | Wide | | Face | Cheekbone | Adjusts cheekbone prominence | Original (0) | Tucked in | | Face | Jaw | Adjusts jawline prominence | Original (0) | Tucked in | | Lips | Size | Scales overall lip volume | Small | Large | | Lips | Width | Adjusts horizontal span | Narrow | Wide | | Lips | Upper Height | Adjusts top lip thickness | Thin | Full | | Lips | Lower Height | Adjusts bottom lip thickness | Thin | Full | | Lips | Peak | Adjusts Cupid's bow sharpness | Smooth | Defined | | Nose | Size | Scales overall nose size | Small | Large | | Nose | Lift | Adjusts vertical position | Low | High | | Nose | Bridge | Adjusts bridge width | Narrow | Wide | | Nose | Tip | Adjusts vertical angle of the tip | Up | Down | | Nose | Wing | Adjusts nostril width | Narrow | Wide | | Nose | Width | Adjusts width of the nose tip | Narrow | Wide | **Note:** *“Left” and “Right” refer to the character's perspective, not the viewer's side of the screen.* --- * Supported Formats & Dimensions |AI Feature|Supported Dimensions|Supported File Size|Supported Formats| | ---- | ---- | ---- | ---- | |AI Face Reshape|long side <= 4096|< 10MB|jpg/jpeg/png| * Error Codes | Error Code | Description | | ---- | ---- | | RUNTIME_ERROR | An unexpected error occurred duface reshape runtime | | PHOTO_DETECTION_FAIL | The user photo could not be processed correctly, for example no hand detected | | OBJECT_DETECTION_FAIL | The object photo could not be processed correctly, for example no product detected | | PHOTO_CHECK_INVALID | The pose or size of the user photo is invalid | | INPUT_ERROR | The input file format is incorrect | | INPUT_MAIN_IMAGE_EMPTY | A user image is required | * Environment & Dependency | Sample Code Language / Tool | Recommended Runtime Versions | |---|---| | cURL | - bash >= 3.2

Type: http Scheme: bearer ## Download OpenAPI description [AI Face Reshape](https://docs.perfectcorp.com/_bundle/reference/ai_face_reshape.yaml) ## V1.0 ### Create a new file. - [POST /s2s/v2.0/file/face-reshape](https://docs.perfectcorp.com/reference/ai_face_reshape/v1.0/paths/~1s2s~1v2.0~1file~1face-reshape/post.md): To upload a new file, you'll first need to use the File API. It will give you a URL – use that URL to upload your file. Once the upload is finished, you can use the file_id from the same response to start using our AI features. ### Run an AI Face Reshape detection task. - [POST /s2s/v2.0/task/face-reshape/pre-process](https://docs.perfectcorp.com/reference/ai_face_reshape/v1.0/paths/~1s2s~1v2.0~1task~1face-reshape~1pre-process/post.md): Use the pre-process task when the source image may contain more than one valid target, or when your integration needs to explicitly choose which detected target receives the effect. For single-target images, pre-process can be skipped when the feature supports a default index value and your application does not need manual target selection. The pre-process task detects candidate targets in the source image and returns their coordinates in data.results.result. Each item in the result array represents one detected target. Review the returned coordinates, map them to the intended face or region in the source image, and use that item's zero-based array index as the index value when creating the effect task. For images with multiple detected faces or regions, do not rely on the default index value without checking the pre-process result. The effect is applied only to the target selected by index, so the integration must confirm the result item that corresponds to the intended target before running the effect task. This task is asynchronous. After creating the task, handle completion with webhook if the feature supports it, or poll the corresponding pre-process status endpoint until data.task_status is success or error. ### Check the status of an AI Face Reshape detection task. - [GET /s2s/v2.0/task/face-reshape/pre-process/{task_id}](https://docs.perfectcorp.com/reference/ai_face_reshape/v1.0/paths/~1s2s~1v2.0~1task~1face-reshape~1pre-process~1%7Btask_id%7D/get.md): Use the pre-process task when the source image may contain more than one valid target, or when your integration needs to explicitly choose which detected target receives the effect. For single-target images, pre-process can be skipped when the feature supports a default index value and your application does not need manual target selection. The pre-process task detects candidate targets in the source image and returns their coordinates in data.results.result. Each item in the result array represents one detected target.

Prefer webhook-based completion handling when the feature supports webhooks. Configure your webhook endpoint, verify webhook signatures, and use the received task_id to query the task result after a success or error notification. See the webhook integration guide for setup and verification details. If webhooks are not supported for the feature, or if your integration cannot use webhooks, implement polling. After starting an AI task, keep polling the task status endpoint at the given polling_interval until the task status is either success or error. Do not stop polling a running task for longer than the allowed polling window. If the task is not polled in time, the task may expire; a later status check can return InvalidTaskId even if processing finished, and the consumed units may still be charged. ### Check the status of a AI Face Reshape task. - [GET /s2s/v2.0/task/face-reshape/{task_id}](https://docs.perfectcorp.com/reference/ai_face_reshape/v1.0/paths/~1s2s~1v2.0~1task~1face-reshape~1%7Btask_id%7D/get.md)
