25,822 APIs for your OpenClaw agent

What are OpenClaw APIs?

OpenClaw APIs are external services your AI agent can call to perform real tasks. Things like sending emails, scraping data, monitoring prices, or posting to social media. Your agent wraps these APIs as skills, and they become actions it can take on command or on a schedule.

How do I connect an API to my OpenClaw agent?

Most APIs here work as Apify Actors. You grab the API URL, add your API key to your OpenClaw config, and write a short SKILL.md file that tells your agent what the API does and how to call it. MCP servers are even simpler: add the server URL and restart.

Are these APIs free to use?

Browsing and discovering APIs in this directory is completely free. Most of the APIs themselves offer free tiers or trial usage through Apify. Heavy usage may require a paid Apify plan, but you can get started at zero cost.

Can I suggest an API to add?

Yes. If you have found an API that works well with OpenClaw and is not listed here, reach out at hello@theoperatorvault.io or share it in our community. We review suggestions and add them to the appropriate category.
