# Dexter — finance research workspace

A single web app with three boards (switch via the left rail):

- **Dexter** — streaming chat/console with an autonomous financial research agent
  (openbb-ai `/v1/query` contract; reasoning steps + citations stream live).
- **Hedge Fund** — the ai-hedge-fund LangGraph "flow" editor to compose and run analyst agents.
- **OpenBB** — market-data query board (quotes, fundamentals, filings, insider trades) over free providers.

One FastAPI server on port `7860` serves the SPA and reverse-proxies the OpenBB REST API
(`/openbb/*`) and the Dexter agent server (`/dexter-api/*`) in-process. Dexter's browser
research uses a headless Lightpanda CDP backend. Internally: Hedge Fund → Dexter (`:7778`) →
OpenBB (`:6900`). No exposed shell/terminal.

### Configuration (Space secrets)
- LLM via freellmapi (OpenAI-compatible): `OPENAI_API_KEY`, `OPENAI_API_BASE`,
  `HELMHOLTZ_API_KEY`, `HELMHOLTZ_BASE_URL` all point at the freellmapi endpoint; model is `auto`.
- `SEC_EDGAR_CONTACT_EMAIL` for SEC filings; optional search keys (`EXASEARCH_API_KEY`, …).
- `GIT_BACKUP_TOKEN` — fine-grained GitHub PAT scoped to the state repo (`STATE_REPO`) to
  persist dexter memory + hedge-fund flows across restarts. Without it the Space is stateless.
