Add Opennan to your AI app

One install gives your AI every Opennan tool: video, images, chat, voice, music, sound effects, 3D, captions and dubbing. Pick your app and follow the steps.

MCP serverhttps://api.opennan.com/v1/mcp

Works in the Codex CLI, the Codex app and the Codex IDE extension: they share ~/.codex/config.toml. If the app or IDE does not see OPENNAN_KEY, use the config.toml option with your key in it. Codex asks before each tool call: approve it to go on.

Get an API key
Create a key in the console. It starts with sk- and uses the same balance as the website.
Create a key

Save your key as OPENNAN_KEY

# macOS / Linux (zsh shown; bash: ~/.bashrc)
echo 'export OPENNAN_KEY="sk-..."' >> ~/.zshrc
source ~/.zshrc

# Windows (PowerShell), then open a new terminal
setx OPENNAN_KEY "sk-..."

3
Install the Opennan plugin: the server plus a skill that teaches your AI to pick models, confirm prices and wait for results
```
codex plugin marketplace add Opennan/opennan-ai-plugin
codex plugin add opennan@opennan
```

Or add only the server

codex mcp add opennan --url https://api.opennan.com/v1/mcp --bearer-token-env-var OPENNAN_KEY

Or add this to ~/.codex/config.toml

[mcp_servers.opennan]
url = "https://api.opennan.com/v1/mcp"
http_headers = { Authorization = "Bearer sk-..." }

4
Check that opennan is listed
```
codex mcp list
```
Restart Codex, then ask for anything
“Make a 5 second video of rain on a neon street, a song to go with it and a poster image.”

Replace sk-... with your own key and keep it private: anyone who has it can spend your balance. Your app can list the tools before you add a key; making anything needs one.

This tool from your AI

Once Opennan is added, your AI calls this tool with arguments like these.

Tool: generate_video
Example arguments: { "model": "wan-2-2-fast", "prompt": "Rain on a neon street at night, slow push-in", "duration": 5 }

Video generation API: questions

Every model and price

How much does Video generation API cost?

From $0.0078/s at 480p with Wan 2.2 Fast, the cheapest of 17 models here. You see the price before you run.

How do I call it from my code?

Send POST https://api.opennan.com/v1/videos/generations with your API key. It answers with a task id: ask https://api.opennan.com/v1/tasks/{id} until the task succeeds or fails.

Can I switch models without changing my code?

Yes. Change the model field and keep the rest of the request, the same key and the same balance.

Can my AI agent use it?

Yes. Add the MCP server https://api.opennan.com/v1/mcp and call the generate_video tool, or point your agent at https://api.opennan.com/llms.txt.

What happens if a run fails?

A failed run is not charged. You pay only for results.
