+# Cloudflare AI Gateway + PostHog AI Examples
+
+Track Cloudflare AI Gateway API calls with PostHog via the OpenAI-compatible unified endpoint.
+
+## Setup
+
+```bash
+cp .env.example .env
+# Fill in your API keys in .env
+# Install uv if you haven't already: https://docs.astral.sh/uv/getting-started/installation/
+uv sync
+```
+
+`POSTHOG_API_KEY`, `OPENAI_API_KEY`, `CF_AIG_TOKEN`, `CF_AIG_ACCOUNT_ID`, and `CF_AIG_GATEWAY_ID` are required. `CF_AIG_TOKEN` is your Cloudflare AI Gateway API token, passed via the `cf-aig-authorization` header.
+
+## Examples
+
+- **chat.py** - Chat completions via Cloudflare AI Gateway
+
+## Run
+
+```bash
+source .env
+uv run python chat.py
+```
