What Financial Modeling Prep Reference (BYOK) is for

Financial Modeling Prep Reference (BYOK) lets an AI assistant read your own Financial Modeling Prep Reference data through the Financial Modeling Prep Reference API with a key you supply (API key). Read-only: 11 tools (search_company_by_name, search_company_by_cik, search_company_by_cusip, search_company_by_isin, search_exchange_variants, list_cik_directory, list_symbol_changes, list_available_exchanges, list_available_sectors, list_available_industries, list_available_countries). 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 financialmodelingprep.com. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by Financial Modeling Prep Reference. Financial Modeling Prep Reference 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 listed companies have Tesla in their name?"
• "Which company has SEC CIK 320193?"
• "Which company has CUSIP 037833100?"
• "Which company has ISIN US0378331005?"
• "On which exchanges is AAPL listed?"
• "List some SEC CIK numbers with their company names"

What it does

• search_company_by_name: Search listed companies and securities by company name; returns matching symbols with the name and exchange. Some endpoints may need a paid plan.

• list_available_countries: List the countries with listed companies in the data service. Some endpoints may need a paid plan.

BYOK key

You bring your own Financial Modeling Prep Reference API key (https://site.financialmodelingprep.com/developer/docs/dashboard). 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 financialmodelingprep.com 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.

Data sources

Financial Modeling Prep Reference (BYOK) — Privacy Policy

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

What Financial Modeling Prep Reference (BYOK) is. Financial Modeling Prep Reference (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own Financial Modeling Prep Reference data: Look up listed companies by name, CIK, CUSIP or ISIN and list exchanges, sectors, industries and countries from Financial Modeling Prep with your own API key. You bring your own Financial Modeling Prep Reference API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one Financial Modeling Prep Reference 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 financialmodelingprep.com, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If Financial Modeling Prep Reference 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 Financial Modeling Prep Reference receives. The request we make on your behalf, including the key and the arguments, under Financial Modeling Prep Reference's own terms and privacy policy. Financial Modeling Prep Reference acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer Financial Modeling Prep Reference 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 Financial Modeling Prep Reference 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. Financial Modeling Prep Reference (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 Financial Modeling Prep Reference at any time to end all access.

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

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