MiniMax H3 Image LoRA API

Introduction

MiniMax H3 Image LoRA Image editing re-renders the people and things in your reference images into a new scene, outfit, pose or style, using the open-weights MiniMax H3 with up to three of your own LoRA files. Send one to nine images, refer to them as Picture 1, Picture 2 and so on, and get one image at 1k or 2k in the first reference's shape or any of fifteen aspect ratios.

Key features

Identity carried over from the references

Faces, hairstyles and distinctive clothing details carry over while everything else changes. In our test a single portrait went into a completely different setting and pose, and the face and hair stayed recognisably the same person.

Up to nine numbered sources

Combine a person, an outfit, an object and a place from separate images in one request. Numbering them in the prompt tells the model which picture does which job.

Request parameters

Pricing

Prices are in credits, the same credits you use on the website (1 credit = $0.01). The hold is taken when the task is accepted and settled to the actual charge when it finishes; failed tasks are refunded.

Each task is rounded up to whole credits, so one run at the lowest tier costs 9 credits per image ($0.09).

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

Use cases

New scenes for the same person

One clean portrait is enough to place someone on a balcony, in a hotel room or on a stage. Change the light and the clothes in the prompt and keep the face from the picture.

Wardrobe and product swaps

Send the person as Picture 1 and a garment or product as Picture 2, and ask for the person wearing or holding it. Useful for catalogues and for keeping a character's outfit consistent.

Restyle with a LoRA

Load an anime, film-stock or VHS LoRA and ask for the same image in that style. The composition and the person stay; the medium changes.

Prompt guide & pro tips

Map the pictures, then describe the change

Start with one short sentence per reference, then describe only what should be different. Describing the face again tends to fight the reference rather than help it.

Fewer, clearer references

Crop references so the part you care about fills the frame.

API quick start

Call the MiniMax H3 Image LoRA 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 minimax/h3-image-lora/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": "minimax/h3-image-lora/edit",
  "input": {
    "prompt": "A ceramic teapot on a linen cloth, soft window light, muted palette",
    "image_urls": [
      "https://media.popnow.ai/influencer/examples/marco.webp"
    ],
    "resolution": "1k",
    "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.
