For developers preparing API checks before running them in Postman, a test framework, or a local environment. Get success, validation, and failure cases for a route, with expected status codes and response assertions. Paste a test snippet to spot missing cases or weak checks. Leave with endpoint test cases, a response checklist, and troubleshooting notes you can use while testing.

What it writes
- Endpoint test cases with expected outcomes
- Status and response assertion checklist
- Test snippet gap and failure notes
How to use it
Include the method, route, authentication type without secrets, and expected success and failure behavior. A sample response makes it easier to write precise field and status assertions.
What you bring
- HTTP method, route, parameters, and headers
- Expected behavior and sample responses
- Test framework preference, if applicable
- Remove credentials and sensitive payloads
A good fit for
- Turning a new endpoint specification into cases before implementation
- Checking validation and error responses for a specific API route
- Reviewing assertion gaps in a pasted API test snippet
Ways to start
A few requests this Agent can handle.
Create tests for POST /v1/orders. A valid order returns 201 with an id and total; missing items should return 400 with an error code.
Review this GET /v1/users test: it checks for status 200 only. The response should include id, email, and role, and email must be valid.
Build success and error checks for PATCH /v1/profile using bearer authentication. A missing displayName should return 422; do not include credentials.
Good to know

- Confirming actual endpoint behavior
- Cannot send requests to your API or execute test code
- Status codes and assertions depend on your stated expectations
