What This Skill Does

The public-apis-skill-creator is a powerful developer-oriented tool designed for OpenClaw agents to interface seamlessly with the public-apis/public-apis repository. It serves as an automated bridge between discovery and implementation. The skill allows agents to search for free, high-quality public APIs based on specific functional requirements, retrieve crucial metadata such as authentication status, HTTPS compliance, and CORS support, and immediately generate production-ready code snippets. Beyond just discovery, it excels in project acceleration by auto-generating complete skill scaffolds, allowing developers to turn a simple idea into an executable OpenClaw skill in seconds.

Installation

To install this skill, use the following command in your terminal or OpenClaw interface:

clawhub install openclaw/skills/skills/547895019/public-apis-skill-creator

Once installed, ensure your environment has the necessary permissions to write to the skills/ directory, as the generator creates new file structures for your custom skills.

Use Cases

• Rapid Prototyping: Quickly fetch and test API endpoints for new feature ideas.
• Boilerplate Generation: Automatically generate standardized code templates for curl, Python, or JavaScript to avoid manual configuration.
• Custom Skill Development: Automatically convert public API endpoints into integrated OpenClaw skills with custom naming conventions.
• Data Sourcing: Efficiently filter through massive lists of public APIs to find those that meet strict security requirements (e.g., HTTPS-only or no-auth endpoints).

Example Prompts

1. "I need a free currency exchange API that doesn't require an API key and supports HTTPS; can you find one and provide a Python example?"
2. "Search for a movie database API, show me the top 3 options, and generate an OpenClaw skill for the best one named 'movie-finder-pro'."
3. "Can you help me build a weather dashboard? Find a free weather API, generate the code for a JS fetch request, and create the basic folder structure for my new skill."

Tips & Limitations

• Pro-Tip: Use the --try flag when picking an API to verify connectivity immediately before generating your code, saving time on debugging broken endpoints.
• Refinement: If search results are too broad, try using more specific keywords related to the data format or industry (e.g., "REST API stock market" instead of just "stock").
• Limitations: Note that this skill relies on the public-apis GitHub repository; if the API provider updates their documentation or deprecates an endpoint, the generated snippets might need manual adjustment. Always verify the source documentation for rate limits or complex authentication flows.
