What FinBrain (BYOK) is for

FinBrain (BYOK) lets an AI assistant read your own FinBrain data through the FinBrain API with a key you supply (FinBrain API key). Read-only: 12 tools (list_tickers, list_markets, get_house_trades, get_senate_trades, get_lobbying_filings, get_government_contracts, get_patent_filings, get_news_sentiment, get_stock_news, get_analyst_ratings, get_put_call_ratio, get_insider_trading). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.finbrain.tech. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by FinBrain. FinBrain and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which tickers are in the S&P 500 list on FinBrain?"
• "Which markets does FinBrain cover?"
• "Which House members traded NVDA this year?"
• "Which senators traded NVDA this year?"
• "How much is Apple spending on lobbying and on which issues?"
• "What federal contracts has Lockheed Martin been awarded recently?"

What it does

• list_tickers: List the ticker symbols and company names FinBrain covers, optionally filtered by market (for example 'S&P 500' or 'NASDAQ'), region or forecast type.

BYOK key

You bring your own FinBrain FinBrain API key (https://terminal.finbrain.tech). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to api.finbrain.tech over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

FinBrain (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What FinBrain (BYOK) is. FinBrain (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own FinBrain data: Read congressional trades, lobbying, patents, news sentiment, analyst ratings and insider trades per stock from FinBrain with your own API key. You bring your own FinBrain FinBrain API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one FinBrain call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to api.finbrain.tech, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If FinBrain rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What FinBrain receives. The request we make on your behalf, including the key and the arguments, under FinBrain's own terms and privacy policy. FinBrain acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer FinBrain gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your FinBrain data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. FinBrain (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at FinBrain at any time to end all access.

Children. FinBrain (BYOK) is a general-audience service operated by the adult using the assistant, under FinBrain's own age rules.

Changes. We will post changes here with a new effective date.
