Build a REST API endpoint with validation
This prompt builds one API endpoint properly: validated input, the right status codes, one error format and no internal details leaked. It also handles two requests arriving at once and includes tests.
Act as a senior backend developer using [STACK, e.g. Node.js with Express and Zod]. Endpoint: [METHOD AND PATH, e.g. POST /api/bookings] What it does: [e.g. creates a booking if the slot is free] Input fields and rules: [LIST] Data store: [e.g. Postgres with Prisma] Write the route with input validation, clear status codes, error responses in one consistent shape, and no internal details leaked to the client. Handle the case where two requests arrive at once. Include two example requests with curl and two tests.
Ask for the error format you already use in your app, so every endpoint answers in the same shape.
