Setup & Installation
openclaw skills install @wanng-ide/api-tester
Or with the ClawHub CLI, for registry-managed skill folders outside a full OpenClaw workspace:
npx clawhub install api-tester
What This Skill Does
A dependency-free HTTP client that performs GET, POST, PUT, and DELETE requests with custom headers and JSON body support. It uses Node.js built-in modules, so no packages need to be installed. Returns structured response objects including status code, headers, parsed body, and errors.
Uses only Node.js built-in http and https modules, so there are no packages to install and no dependency conflicts to manage.
When to use it
- Testing a new REST API endpoint during development
- Running automated health checks against remote services
- Posting JSON payloads to a webhook from an agent workflow
- Verifying that an authentication token works against a live API
- Fetching data from a third-party API without leaving the agent environment
