short_description: Dexter research + hedge-fund + OpenBB, one app

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.
