Api Tester

What it does

The api-tester skill allows AI agents to send requests to APIs and analyze the responses. It can execute API calls with various methods (GET, POST, PUT, DELETE) and validate response status codes and body contents against expected values. This enables automated testing and verification of API functionality directly within an agent's workflow.

When to use it

• Automated Regression Testing: Regularly test APIs after code changes to ensure existing functionality remains intact.
• Integration Verification: Confirm that different systems or services communicate correctly via their APIs.
• Data Validation: Check if API responses contain the expected data and adhere to defined schemas.
• Workflow Automation: Integrate API testing into a larger automated workflow, such as deployment pipelines.

Key capabilities

• Supports various HTTP methods (GET, POST, PUT, DELETE)
• Response status code validation
• Body content validation against expected values

Example prompts

• "Test the /users endpoint with a GET request and verify that the response status is 200."
• "Send a POST request to /orders with the following JSON payload: { "item": "widget", "quantity": 10 } and check if the response contains an 'order_id'."
• “Use a PUT request to update user ID 123, ensuring that the status code is 204.”

Tips & gotchas

The skill requires knowledge of API endpoints, HTTP methods, expected data formats, and validation criteria. Ensure the AI agent has access to the necessary API keys or credentials for authentication if required.
