What SEC API Corporate Events (BYOK) is for

SEC API Corporate Events (BYOK) lets an AI assistant read your own SEC API Corporate Events data through the SEC API Corporate Events API with a key you supply (sec-api.io API key (paste it as is)). Read-only: 8 tools (search_subsidiaries, search_audit_fees, search_financial_statement_audit_reports, search_icfr_audit_reports, search_auditor_changes, search_restatements, search_cybersecurity_incidents, search_shareholder_meetings). 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 Corporate Events. SEC API Corporate Events 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 subsidiaries does Tesla list and where are they incorporated?"
• "How much did Tesla pay its auditor in audit fees in recent proxy statements?"
• "Which recent audit reports carried a going concern warning?"
• "Which companies reported material weaknesses in internal control this year?"
• "Which companies changed their auditor in 2022?"
• "Which companies announced financial restatements this year?"

What it does

• search_subsidiaries: Search the subsidiaries listed in company annual reports (Exhibit 21) by ticker or CIK; each filing returns the subsidiary names and jurisdictions.
• search_audit_fees: Search audit, audit-related, tax and other fees paid to auditors as disclosed in proxy statements, by company and period.
• search_financial_statement_audit_reports: Search auditor reports on financial statements: opinion type, going-concern flag, critical audit matters and auditor firm.
• search_icfr_audit_reports: Search auditor reports on internal control over financial reporting: framework, opinion, effectiveness and material weaknesses.
• search_auditor_changes: Search Form 8-K Item 4.01 filings about changes of the company's auditor: former and new accountant, reason and any disagreements.
• search_restatements: Search Form 8-K Item 4.02 filings announcing that earlier financial statements should no longer be relied on: reasons, affected periods and impact.
• search_cybersecurity_incidents: Search Form 8-K Item 1.05 disclosures of material cybersecurity incidents: attack types, data affected, impact and response.
• search_shareholder_meetings: Search the calendar of shareholder meetings taken from proxy statements: meeting date, type, format, record date and voting deadlines.

BYOK key

You bring your own SEC API Corporate Events 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 Corporate Events (BYOK) — Privacy Policy

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

What SEC API Corporate Events (BYOK) is. SEC API Corporate Events (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own SEC API Corporate Events data: Search SEC filing data on subsidiaries, audit fees, audit reports, auditor changes, restatements, cyber incidents and shareholder meetings with your own sec-api.io key. You bring your own SEC API Corporate Events 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 Corporate Events 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 Corporate Events 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 Corporate Events receives. The request we make on your behalf, including the key and the arguments, under SEC API Corporate Events's own terms and privacy policy. SEC API Corporate Events 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 Corporate Events 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 Corporate Events 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 Corporate Events (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 Corporate Events at any time to end all access.

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

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