Pose Changer API

About Pose Changer

Repose a person from a short description or a pose photo.

Call it with the model name popnow/pose-changer-v1/edit on POST /jobs/createTask, from 30 credits per image ($0.03).

Introduction

Pose Changer moves a person into a new pose. You send two photos, the person and a pose reference, and get back the first person holding the second photo's pose: arms, legs, head tilt and gaze, with their own face and outfit.

Key features

Two photos, no prompt

The tool runs Qwen-Image-Edit-2511 with the AnyPose base and helper LoRAs by lilylilith and the author's instruction. The prompt field is only for extra direction.

The LoRAs make the difference

With the same photos and seed, the base model without the LoRAs pasted the dancer from the pose photo into the first scene. With them, the woman from the first photo took the dancer's pose.

Keep your scene with one line

Out of the box the result often takes the pose photo's backdrop. Adding "Remove the background of image 2, and replace it with the background of image 1." kept a wood-panelled library and a salt flat in our runs.

Request parameters

Pricing

Prices are in credits, the same credits you use on the website (1 credit = $0.001). The hold is taken when the task is accepted and settled to the actual charge when it finishes; failed tasks are refunded.

For an exact number before you run, send the same body to POST /jobs/quote.

Use cases

Catalogue variants

Turn one shot of an outfit into standing, seated and leaning versions from simple pose references shot against a plain wall, without rebooking the model or the location.

Consistent characters

Keep a character's face and costume while changing the pose a scene needs, so a storyboard or a comic keeps one recognisable cast.

Pose libraries

Keep a folder of reference poses shot on a plain backdrop and apply them to any portrait.

Prompt guide & pro tips

Match the build

Copying a woman's pose onto a man in our tests pulled his face toward hers. A reference of a similar build and gender kept the identity.

Name what must stay

If the outfit changes, say so: "She keeps her emerald satin dress." fixed a case where sweatpants from the reference appeared.

Show the whole body

Full-body photos on both sides give the cleanest result; a waist-up source forces the model to invent legs and floor.

Keep one person per photo

Group shots in either photo confuse which body to move and which pose to copy. Crop to one person first, then run each person separately.

API quick start

Call the Pose Changer API in three steps

1. Create an API key. Sign in to PopNow and create a key in the API console. Keys start with sk-popnow- and use the same credits as the website.
2. Send the request. POST /jobs/createTask with model popnow/pose-changer-v1/edit and an input object that follows the parameter table. The response returns a task ID straight away.
3. Get the result. Poll GET /jobs/recordInfo with the task ID, or pass a callBackUrl and we post the result to it. Download the output links when the task succeeds.

# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.
export IDEMPOTENCY_KEY="$(uuidgen)"
curl -X POST https://api.popnow.ai/api/v1/jobs/createTask \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY" \
  -d '{
  "model": "popnow/pose-changer-v1/edit",
  "input": {
    "image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
    "reference_image_url": "https://media.popnow.ai/influencer/examples/ava.webp",
    "output_format": "jpeg"
  }
}'

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.
TASK_ID="TASK_ID_FROM_RESPONSE"
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
  -H "Authorization: Bearer $POPNOW_API_KEY"

Replace the prompt and any links with your own. The API tab has the response, polling and callback reference.
