This checker answers a practical API testing question: which documented endpoints are missing from a Postman collection? Paste an OpenAPI JSON document and a Postman collection JSON export to compare coverage locally.

How matching works

The tool compares HTTP method plus normalized path shape. Numeric URL segments and OpenAPI path parameters are treated as parameter slots, so GET /orders/123 can match GET /orders/{id}.

Scope

This is endpoint coverage, not assertion quality. It does not run the collection, validate schemas or inspect test scripts.
