Add AgentUtil to OpenClaw

AgentUtil tools are available as an OpenClaw skill. Install it in under a minute.

Install the Skill

Option A: From the Skills Registry

openclaw skill install agentutil

Option B: Manual Install

mkdir -p ~/.openclaw/workspace/skills/agentutil
curl -o ~/.openclaw/workspace/skills/agentutil/SKILL.md https://agentutil.dev/skill.md

Then restart OpenClaw or ask it to refresh skills.

Configure Payment

You have two options for paying for API calls.

x402 (recommended)

Set up a wallet with USDC on Base. See the wallet setup guide for instructions. The skill handles 402 responses automatically if your OpenClaw instance has a configured wallet.

API Key

Get a key from agentutil.dev/api-key, then set it as an environment variable:

export AGENTUTIL_API_KEY=sk_live_xxxxx

Or add it to your OpenClaw environment config.

What You Can Do

Once installed, you can ask OpenClaw things like:

  • "Verify if hello@company.com is a real email address"
  • "Look up the DNS records for stripe.com"
  • "What's the geolocation of IP 8.8.8.8?"
  • "Check if https://example.com is reachable"
  • "Find me a plumber near 94110"
  • "Take a screenshot of https://news.ycombinator.com"

Troubleshooting

  • Skill not loading — Check that SKILL.md has no leading spaces in the frontmatter.
  • 402 errors — Your wallet needs USDC on Base, or set AGENTUTIL_API_KEY as a fallback.
  • Task stuck in pending — Poll again after a few seconds. Most tools complete in under 5s.
