MiniMax H3 Image LoRA API

About MiniMax H3 Image LoRA

MiniMax H3 Image LoRA uses the open-weights MiniMax H3 video generator to make single stills, with up to three of your own LoRA files loaded per request. Text-to-image and reference editing with up to nine sources, at about one or four megapixels in fifteen aspect ratios. The same LoRAs you use for H3 video work here, and nothing is filtered.

Call it with the model name minimax/h3-image-lora/text-to-image on POST /jobs/createTask, from 7 credits per image ($0.07). New accounts get 30 free credits to try it in the Playground first.

Introduction

MiniMax H3 Image LoRA Text to image makes one still from a written prompt using the open-weights MiniMax H3 video generator, with up to three of your own LoRA files loaded. Choose 1k, about one megapixel, or 2k, about four, in any of fifteen aspect ratios, and get back JPEG, PNG or WebP.

Key features

A video model's frame, as a still

This endpoint runs the same generator as the H3 video families and returns a single frame. The result reads like a film still: directional light, shallow depth of field and natural skin rather than a glossy render.

The same LoRAs as your H3 videos

Because it is the same model, character and style LoRAs trained for MiniMax H3 apply here unchanged, up to three per request with their own strengths. A VHS style LoRA we use on video produced the same tape look on a still.

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 7 credits per image ($0.07).

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

Use cases

Opening frames for video

Design the first frame of a clip here with your character LoRA, then send it to MiniMax H3 LoRA image-to-video. The still and the motion share one model, so the look does not jump between them.

Style sheets for a character

Keep a character LoRA and seed fixed and change only the outfit, place and light between prompts to build a consistent set of stills.

Prompt guide & pro tips

Light it like a film shot

Name the light source, its direction and its colour, then the lens feel: a warm lamp from the left, blue window light behind, shallow depth of field. H3 was trained on video, and lighting language lands better than style adjectives.

Trigger first, then the picture

Most community LoRAs expect their trigger word at the start of the prompt. After it, describe the subject and the setting and let the weights carry the style.

Draft at 1k, finish at 2k

1k images come back in seconds. When a draw is right, keep the seed and re-run at 2k for the final. Change one LoRA scale at a time when you compare.

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/text-to-image 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/text-to-image",
  "input": {
    "prompt": "A ceramic teapot on a linen cloth, soft window light, muted palette",
    "aspect_ratio": "1:1",
    "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.
