How to connect
Three steps to a smarter agent.
Pick an API from the list above
Browse or search through the directory. Each API links directly to its documentation and setup instructions.
Add it to your OpenClaw config as a skill or MCP server
For MCP servers, add the URL to your config and restart. For skills, create a folder with a SKILL.md and set your API key. Takes about five minutes.
Your agent uses it automatically on every task
Once connected, your agent can call the API in conversations across WhatsApp, Telegram, Slack, or any connected channel. Set up cron jobs for recurring tasks.
