Install Delx Commerce — Pay-per-Result APIs for Agents in oterm

What you need first

• oterm, installed.
• Nothing else: the server runs on its publisher's machines and oterm connects to it.

Steps

1. Open ~/.codex/config.toml, or create it. The Codex CLI, its IDE extension and the ChatGPT desktop app share this file.
2. Add this table at the end of the file.

{
  "mcpServers": {
    "delx-mcp-a2a": {
      "url": "https://api.delx.ai/v1/mcp?src=registry-commerce"
    }
  }
}

3. Save the file and restart oterm.

Check it worked

Ask oterm: List the tools of delx-mcp-a2a.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when oterm asks.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
