Undocumented Endpoint Finder
Cross-reference HAR traffic against an uploaded OpenAPI spec to identify undocumented paths and shadow API endpoints. Free by Graph Tools.
Use this free undocumented endpoint finder to cross-reference real API traffic from a HAR file against an uploaded OpenAPI specification and surface any paths that were called but are not declared in the spec. These undocumented endpoints are shadow APIs — a key risk category in OWASP API9. Upload both your HAR and OpenAPI files and get a prioritized list of undocumented paths with call frequency. Useful for security auditors, platform teams, and API governance reviewers.
