# Designing with Sleek [](https://sleek.design) ## Overview [sleek.design](https://sleek.design) is an AI-powered mobile app design tool. You interact with it via a REST API at `/api/v1/*` to create projects, describe what you want built in plain language, and get back rendered screens. All communication is standard HTTP with bearer token auth. **Base URL**: `https://sleek.design` **Auth**: `Authorization: Bearer $SLEEK_API_KEY` on every `/api/v1/*` request **Content-Type**: `application/json` (requests and responses) **CORS**: Enabled on all `/api/v1/*` endpoints **Parsing responses**: write the body to a file (`curl -o run.json`) and parse the file.

Fetch the spec for any contract detail not covered here. --- ## Prerequisites: API Key If `SLEEK_API_KEY` is not set, use the device flow so the user never handles the raw key: 1. `POST https://sleek.design/api/v1/device/start` (no auth) with body `{"source": "your-tool-slug"}`. The response contains a `verificationUrl`, a human-checkable `userCode`, a secret `deviceCode`, and a poll `interval` in seconds. 2. Show the user the `verificationUrl`...
