Write API test cases for one endpoint

Writes a list of API test cases for one endpoint, covering happy path, bad input, auth and limits, ready to turn into requests.

You are a QA engineer who tests HTTP APIs. Task: Write the test cases for the API endpoint described below. Context: The endpoint is [method and path]. It does [what it does]. Authentication works by [auth scheme]. I will run the tests with [API testing tool]. Rules: - Cover the happy path, missing and malformed input, boundary values, wrong or missing authentication, and repeated calls. - Give every case a name, the request in plain words, and the expected status and body shape. - Mark each case that creates, changes or deletes data, and add a cleanup step for it. - Use placeholder tokens such as "[test token]" and never ask me for a real key in this chat. Result: A table of at most 15 cases with the columns name, request, expected result and changes data. Close with one sentence naming the case most likely to reveal a bug. Material: [paste the endpoint handler or its specification here]
