SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Debugging REST and GraphQL APIs to identify where failures originate, enabling faster repair and higher reliability across services.

Core Features & Use Cases

  • Isolated debugging workflow for API endpoints using curl, Python requests, and vendor docs.
  • Structured playbook for common errors (auth, content-type, timeouts, payloads) and reproducible repro steps.
  • Use Case: quickly reproduce a failing /endpoint and validate headers, status codes, and response shapes to guide fixes.

Quick Start

Run a basic health check and then iteratively test an API endpoint using curl and Python requests to reproduce and fix the issue.

FAQPage Schema
How do I debug REST API failures and isolate the problematic layer?

To debug REST API failures, isolate the problematic layer from connectivity to data semantics by checking HTTP status codes, authentication, payload formatting, and response parsing. Use a structured playbook to reproduce reproducible steps and validate headers.

What is the best way to diagnose GraphQL API errors using curl and Python?

Diagnosing GraphQL API errors involves running a basic health check and iteratively testing the endpoint using curl and Python requests. This workflow validates token handling, schema checks, and response shapes to guide fixes for data semantic issues.

How do I troubleshoot API authentication and payload formatting issues?

Troubleshoot API authentication and payload formatting issues by applying an isolated debugging workflow across HTTP status and content-type scenarios. Execute curl-based and Python-based requests to reproduce the failure condition and validate headers.

Can I use Python requests and curl to test vendor API documentation?

Yes, you can use Python requests and curl alongside web extraction of vendor docs to test vendor APIs. This approach validates endpoint behavior against documented schemas, ensuring response parsing and token handling match expected specifications.

Why does my API request timeout or return unexpected response shapes?

API requests timeout or return unexpected response shapes due to connectivity issues, incorrect payload formatting, or data semantic mismatches. Isolate the failure by executing terminal requests and validating the response parsing against schema checks.

Do I need to install dependencies to isolate API connectivity issues?

No dependencies are required to isolate API connectivity issues. The workflow uses standard terminal tools for curl requests and execute_code for Python requests, requiring only clear reproducible steps and failure conditions to guide repairs.
