+# + uvicorn (FastAPI). Port 7860 is what HF Spaces expects.

+#   2. py-builder   — pip install into an isolated venv

+> **[huggingface.co/spaces/adityapatel007-byte/structured-data-extractor](https://huggingface.co/spaces/adityapatel007-byte/structured-data-extractor)** — always-on, free tier
+
+Locally: `docker compose up --build` after cloning; hit [http://localhost:5173](http://localhost:5173).
+
+## Deploy your own to HF Spaces
+
+1. Create a new [HF Space](https://huggingface.co/new-space) → **Docker SDK**, blank template.
+2. Add `OPENAI_API_KEY` under **Settings → Repository secrets**.
+3. Point the Space at this repo (or push a fork). HF reads the YAML frontmatter
+   at the top of this README (`sdk: docker`, `app_port: 7860`), builds the root
+   `Dockerfile`, and exposes it on your Space URL. First build ~5-8 min; every
+   redeploy ~2-3 min thanks to layer caching.
