Use the exact API model ID minimax-h3. This guide describes the platform contract; check the live catalog before calling the model.

Request example

The platform origin is filled in at build time. Set API_KEY to your server-side key before running.

curl "https://newrouters.com/v1/tasks" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $API_KEY" \
  --data '{
  "model": "minimax-h3",
  "input": {
    "seconds": 5,
    "resolution": "480P",
    "aspect_ratio": "16:9",
    "aigc_watermark": false,
    "prompt": "A small red house in a quiet garden"
  }
}'

Retrieve the result

The creation response accepts a task, not the final output. Replace TASK_ID with its returned ID and poll until succeeded or failed.

curl "https://newrouters.com/v1/tasks/TASK_ID" \
  -H "Authorization: Bearer $API_KEY"

Read result on success and error on failure. Keep the original task ID when the upstream outcome is unknown; do not submit a duplicate paid generation.

Task workflow and budget

Follow the task tutorial, then use batch budgeting to reconcile specifications, attempt counts and final charges. Examples do not promise output quality or speed; validate an approved small sample first.
