Quickstart

1. Get an API key

Sign in and generate a key from the MCP page. Keys are prefixed cbx_ and shown once — store it securely.

2. Call the REST API

Public signal endpoints need no auth:

curl https://www.contrabxnd.io/api/signal
curl https://www.contrabxnd.io/api/hashrate
curl https://www.contrabxnd.io/api/onchain

3. Connect the MCP server

Point any MCP-compatible client at the server with your key:

{
  "mcpServers": {
    "contrabxnd": {
      "url": "https://www.contrabxnd.io/api/mcp",
      "headers": { "Authorization": "Bearer cbx_YOUR_KEY" }
    }
  }
}

From there, an agent can call get_signal_score, query_address,get_mining_intelligence, and more. See the Tool Reference.
