What SEC API Mapping (BYOK) is for

SEC API Mapping (BYOK) lets an AI assistant read your own SEC API Mapping data through the SEC API Mapping API with a key you supply (sec-api.io API key (paste it as is)). Read-only: 7 tools (resolve_cik, resolve_ticker, resolve_cusip, resolve_company_name, list_companies_by_exchange, list_companies_by_sector, list_companies_by_industry). 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.sec-api.io. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by SEC API Mapping. SEC API Mapping 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 company has SEC CIK 1318605?"
• "Which company trades under the ticker TSLA?"
• "Which company has CUSIP 88160R101?"
• "What is the ticker and CIK of Snowflake?"
• "List NYSE American listed companies"
• "List companies in the Utilities sector"

What it does

• resolve_cik: Look up the company record for an SEC Central Index Key (CIK). Returns an array of company records (name, ticker, CIK, CUSIP, exchange, delisted flag, sector, industry, SIC codes, location).
• resolve_ticker: Look up companies by ticker symbol; by default every ticker containing the text matches, so wrap it as ^IBM$ for an exact match. Returns an array of company records (name, ticker, CIK, CUSIP, exchange, delisted flag, sector, industry, SIC codes, location).
• resolve_cusip: Look up the company record for a CUSIP identifier. Returns an array of company records (name, ticker, CIK, CUSIP, exchange, delisted flag, sector, industry, SIC codes, location).
• resolve_company_name: Look up companies or funds by name, case-insensitive, for example snowflake. Returns an array of company records (name, ticker, CIK, CUSIP, exchange, delisted flag, sector, industry, SIC codes, location).
• list_companies_by_exchange: List companies (listed and delisted) on one exchange; the list can be long, so check isDelisted and use the cap. Returns an array of company records (name, ticker, CIK, CUSIP, exchange, delisted flag, sector, industry, SIC codes, location).
• list_companies_by_sector: List companies (listed and delisted) in one of the 11 sectors; the list can be long. Returns an array of company records (name, ticker, CIK, CUSIP, exchange, delisted flag, sector, industry, SIC codes, location).
• list_companies_by_industry: List companies (listed and delisted) in one of 175 industries, for example Software - Application or Banks - Regional. Returns an array of company records (name, ticker, CIK, CUSIP, exchange, delisted flag, sector, industry, SIC codes, location).

BYOK key

You bring your own SEC API Mapping sec-api.io API key (paste it as is) (https://sec-api.io/signup/free). 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.sec-api.io 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.

SEC API Mapping (BYOK) — Privacy Policy

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

What SEC API Mapping (BYOK) is. SEC API Mapping (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own SEC API Mapping data: Resolve SEC CIK, ticker, CUSIP and company names to company records and list companies by exchange, sector or industry with your own sec-api.io key. You bring your own SEC API Mapping sec-api.io API key (paste it as is); the assistant sends it to us with each request.

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

What we return. The answer SEC API Mapping 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 SEC API Mapping 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. SEC API Mapping (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 SEC API Mapping at any time to end all access.

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

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