curl https://api.openmayhem.ai/v1/workflows \
-H "Authorization: Bearer $OPENMAYHEM_API_KEY" \

-d '{
"model": "video.minimax_h3.spectrum",
"workflow": {"<node-id>": {"class_type": "<allowed-node>", "inputs": {}}}
}'MCP
OpenMayhem runs its own MCP server, so Claude, Codex, Cursor and other AI apps can call this model and pay from your credit.
claude mcp add --transport http openmayhem \ https://mcp.openmayhem.ai/mcp \ --header "X-OpenMayhem-API-Key: $OPENMAYHEM_API_KEY"
Then ask your app, for example: "Use OpenMayhem MiniMax H3 SPECTRUM to answer this." It calls generate_video with video.minimax_h3.spectrum. Apps that support sign-in connect without a key, and you approve spending limits once.

Use this model through MCP
These calls use this model’s exact live request contract. First estimate the unchanged request, then pass the returned estimate ID and maximum cost to the paid tool. Read the complete MCP guide.
run_workflowWORKFLOWS +
Send this object to estimate_request. Review the result, then send the next object to the named paid tool without changing request.

Questions and answers
What does MiniMax H3 SPECTRUM cost on OpenMayhem?
MiniMax H3 SPECTRUM currently costs $0.000025875 per megapixel-frame. There is no subscription: you buy credit and every request settles against a signed receipt for exactly what it used. Prices are versioned, and the full price history is published on this page.
Is MiniMax H3 SPECTRUM available right now?
No providers are online for MiniMax H3 SPECTRUM at this moment. Availability is polled every minute, and requests are rejected upfront rather than queued indefinitely.
How do I use MiniMax H3 SPECTRUM?
Send an OpenAI-compatible request to https://api.openmayhem.ai/v1/workflows with "model": "video.minimax_h3.spectrum" and your API key. Existing OpenAI SDKs work by changing the base URL. Create an account to get a key and starting credit.
Are my prompts stored?
OpenMayhem does not persist prompt or completion text. Requests are proxied to the serving provider and only billing metadata is retained: usage counts, the price applied, and the provider's signed receipt. Generated media files are stored temporarily so you can download them, then expire. The provider that serves a request necessarily processes its content.
