🔎 API Error Parser

API Error Parser is a simple Streamlit tool that helps developers and QA engineers understand API error responses faster.

Paste an HTTP status code and an API error payload, and the tool will:

• Explain the meaning of the error
• Extract common error fields
• Suggest likely causes
• Provide debugging steps

Built with Python + Streamlit.

❓ Why This Tool Exists

When an API fails, the response body is often too raw or too technical for quick debugging.

This tool turns common API errors into a more human-readable explanation, which is useful for:

• QA engineers
• Backend developers
• Frontend developers
• Automation engineers
• Anyone debugging REST API responses

Example use cases

• Understand what a 500 Internal Server Error may really mean
• Parse a 422 validation_failed response body
• Diagnose 401 unauthorized or token expiration issues
• Investigate 429 rate limit exceeded errors

✨ Features

• Parse HTTP status codes such as 400, 401, 403, 404, 422, 429, 500, 502, 503, and 504
• Extract common fields like error, message, details, code, and request_id
• Detect likely categories such as:
  • Authentication
  • Authorization
  • Validation
  • Timeout
  • Rate limit
  • Resource not found
• Provide practical debugging suggestions
