How to use OpenAPI Operation Extractor
- Load the included example or provide your own input and settings.
- Choose the operation and review the supported format below.
- Run the tool, inspect the result, and copy or download it.
Create an endpoint inventory
Paste an OpenAPI 3.x or Swagger 2.0 document in JSON form to list the operations under paths. The result retains each exact path, HTTP method, operation identifier, summary, tags and deprecation flag. Use the inventory when reviewing an unfamiliar API, preparing migration notes or checking which methods belong to a resource. Path-level metadata is not mistakenly counted as an operation.
Know what is outside the inventory
The extractor inspects the supplied document without fetching references or contacting API servers. Referenced path items are listed separately because their operations may live elsewhere. Callbacks, webhooks, inherited security rules and parameter resolution are not expanded. This is an inventory helper rather than a complete OpenAPI validator. Convert YAML to JSON first, and use the original specification when interpreting authentication or request requirements.
