Integrate Linkup with OpenClaw to give your self-hosted agent real-time web search via the clawhub skill registry.

​
Prerequisites

  • OpenClaw installed and running (quick start)
  • A Linkup API key — get one at app.linkup.so
  • clawhub CLI: npm i -g clawhub

​
Installation

Install the Linkup skill from clawhub: 
clawhub install linkup-search
clawhub list  # verify
Alternatively, ask your OpenClaw agent directly:
“Install the Linkup skill from clawhub.”
The skill will be available at the next session start. No restart required if the skills watcher is enabled. The skill is available on ClawHub.

​
Configuration

Add your API key to openclaw.json: 
{
  "skills": {
    "entries": {
      "linkup-search": {
        "enabled": true,
        "env": {
          "LINKUP_API_KEY": "your-api-key-here"
        }
      }
    }
  }
}
This scopes the key to the skill, which is preferable for multi-agent setups over using a .env file.

​
How It Works

OpenClaw injects the skill’s instructions into the system prompt at session start. The agent calls Linkup when a query requires current information, instead of relying on training data. A typical call looks like: 
POST https://api.linkup.so/v1/search
{
  "q": "Stripe payment processing fees 2025",
  "depth": "standard",
  "outputType": "sourcedAnswer"
}
Linkup returns a structured, source-cited answer. The agent reasons over the result and formats the reply. Depth selection:
  • standard — optimized for latency. Use for single-fact lookups.
  • deep — higher recall, multi-source synthesis. Use for company research, competitive analysis, or page extraction.
The agent automatically decides which depth to use based on the complexity of the query.
