Check the Exact H3 Max Model IDs Before You Integrate

MiniMax H3 Max is available on RouterBase in text-to-video and image-to-video modes. Before wiring it into an application, check the API model IDs rather than copying a model-page URL.

On September 7, 2026, RouterBase’s public catalog returned:

• minimax/minimax-h3-max-t2v
• minimax/minimax-h3-max-i2v

A read-only catalog check

This Node.js script checks both IDs without submitting a generation job:

const expected = [
  "minimax/minimax-h3-max-t2v",
  "minimax/minimax-h3-max-i2v",
];
const response = await fetch("https://routerbase.com/v1/models");
if (!response.ok) throw new Error(`Catalog HTTP ${response.status}`);
const { data } = await response.json();
if (!Array.isArray(data)) throw new Error("Unexpected catalog response");
const available = new Set(data.map(model => model.id));
const missing = expected.filter(id => !available.has(id));
if (missing.length) throw new Error(`Missing: ${missing.join(", ")}`);
console.log("Both H3 Max model IDs are present.");

Save it as check-h3-max.mjs and run it in a Node.js runtime with built-in fetch. This verifies catalog presence; it does not test generation latency or output quality.

Pick the input workflow

Use text-to-video for a scene described from scratch. Use image-to-video when a still image should anchor the opening frame. RouterBase’s pages list 5–15 seconds, 480P or 768P, and synchronized audio.

H3 Max is fal’s post-trained variant of MiniMax H3. Use RouterBase’s current request documentation when integrating; fal’s SDK examples describe fal’s API.

Next: open the text-to-video page or image-to-video page and review the required inputs before a paid generation.
