Axios 404 Inspector

The Axios 404 Inspector analyzes failed API calls that return HTTP 404 in Axios-based flows. It accepts a minimal structured input consisting of the request details (URL, HTTP method, headers, and body), the observed response (status code 404, response headers, payload), and the execution environment (base URL, proxy usage, auth). The tool categorizes common 404 causes such as incorrect path, truncated routes, missing resource, base URL misconfiguration, or environment-specific routing rules. It does not perform network calls.
Core logic identifies URL patterns, compares against provided OpenAPI specs if present, and correlates route availability with environment context to produce concrete remediation steps. Features include input validation, route-template matching, cause inference, and optional test artifacts such as curl commands and Axios snippets.
Outputs guide users toward root causes (e.g., wrong path, base URL mismatch, or stale cache) and offer concrete fixes, including corrected URLs, route enablement, and deployment considerations.
This tool targets developers, QA engineers, and site reliability engineers who debug API integrations and microservice communications. It uniquely combines route-aware analysis with environment context to reduce blind guesswork, and it can produce reproducible test commands for quick verification.
