MiniMax H3 Max Lip Sync

About

Makes a face say an audio track · 480p to 1080p

Model id minimax-h3-max-lip-sync, sent to POST https://api.sume.com/v1/video-router/generate.

1. Calling the API

Install the client

npm install @sume-com/client

Setup your API key

Set SUME_API_KEY as an environment variable in your server runtime. Make the key in Sume API → API keys.

export SUME_API_KEY="YOUR_API_KEY"

Submit a request

This sends the Playground's request, with the input it holds now. Change the input there and this updates. subscribe submits it, waits for the job and returns the result.

import { createSumeClient } from "@sume-com/client";

const sume = createSumeClient({ baseURL: "https://api.sume.com" });

const response = await sume.subscribe("/v1/video-router/generate", {
  input: {
    "model": "minimax-h3-max-lip-sync",
    "image_url": "https://media.sume.com/artifacts/artf_2VwoDBdaM2_88dqPa_CWF9KONvewNHmy/images.png",
    "audio_url": "https://media.sume.com/artifacts/artf_RT_e13chUs2gYQf_nfYHwewKTFz_Rz-r/tts-audio.mp3",
    "resolution": "480p",
    "duration": 7
  },
});

console.log(response.status, response.video?.url);

2. Authentication

API key

Send your Sume API key as a bearer token from server code only. Keys made under Sume API → API keys spend the workspace balance, the same one Studio spends, and call the model API only.

Authorization: Bearer $SUME_API_KEY

3. Queue

A submit answers at once with the job. Poll its status until it is completed, failed or canceled. Failed and canceled jobs are refunded.

Fetch request status

const response = await fetch(`https://api.sume.com/v1/jobs/${jobId}/status`, {
  headers: { authorization: `Bearer ${process.env.SUME_API_KEY}` },
});
const { data: job } = await response.json();

Get the result

A completed job returns its media. A queued or running job answers 409 job_not_completed with the current status; a failed one 409 job_failed with the reason, and a canceled one 409 job_canceled.

const response = await fetch(`https://api.sume.com/v1/jobs/${jobId}/result`, {
  headers: { authorization: `Bearer ${process.env.SUME_API_KEY}` },
});
const { data: result } = await response.json();

Cancel a request

A job can be canceled until generation starts.

const response = await fetch(`https://api.sume.com/v1/jobs/${jobId}/cancel`, {
  method: "POST",
  headers: { authorization: `Bearer ${process.env.SUME_API_KEY}` },
});
const { data: job } = await response.json();

4. Files

Hosted files (URL)

Fields that end in _url or _urls take public HTTPS URLs. Some hosts block or rate-limit fetches from servers.

Uploading files

Upload a local file to Sume's storage, then send the URL it returns.

import { readFile } from "node:fs/promises";
import { createSumeClient } from "@sume-com/client";

const sume = createSumeClient({ baseURL: "https://api.sume.com" });

const url = await sume.uploadImage(await readFile("input.png"), "png");
