OpenAPI required-params finder
Written by Agorean from what the endpoint says about itself
Tells you the minimum inputs an API operation needs to succeed.
For one API operation, it returns the minimum set of inputs an agent must provide to make a successful call. You locate the operation by its operationId, or by method and path. The output is a single flat array tagged by where each input goes: path parameters, which are always required; query, header, or cookie parameters only when marked required; and body.field entries naming the top-level required fields of a required JSON body.
WHEN TO USE THIS
When: I need to know what an API operation requires before I call it
For example: Look it up by operationId to get its minimum required inputs.
When: I only know an operation's method and path, not its operationId
For example: Look it up by method and path instead.
When: I need to know which required fields belong in the request body
For example: Read the body.field entries for the top-level required fields.
When: I need to separate required query, header, and cookie parameters
For example: Read the tagged array to see which ones are marked required.
