# FinChat API (headless)

FastAPI backend for **FinChat** — a Retrieval-Augmented Generation chatbot over
SEC 10-K filings. This Space is **headless**: it has no UI of its own. It serves
a JSON API that the FinChat web app (hosted on Vercel) calls.

**Endpoints**

| Method | Path         | Purpose                                  |
|--------|--------------|------------------------------------------|
| GET    | `/health`    | Liveness probe                           |
| GET    | `/companies` | Companies loaded in the corpus           |
| POST   | `/chat`      | `{question}` → `{answer, routed_to, sources}` |
| GET    | `/docs`      | Interactive Swagger UI                    |

The user-facing app lives on Vercel (set its URL after you deploy the front-end).
