Returns SEC Schedule TO filings — public tender offer disclosures

Returns SEC Schedule TO filings — public tender offer disclosures. Use this when the user asks about: who's bidding to acquire company X, what M&A offers are in flight, share buyback announcements, amendments to existing tender offers (price increases / extensions), or to pair with 13D activist stakes for the 'stake → bid' story. Source: SEC EDGAR full-text search. Forms covered: SC TO-T (third- party tender offer — someone outside the company bidding for shares), SC TO-T/A (amendments), SC TO-I (issuer tender offer — company buying back its own shares), SC TO-I/A (issuer amendments). v1 returns filing metadata only — bidder + target + form type + filing date + URL. Offer price, shares sought, and expiration date live inside the HTML attachment at primary_document_url; agents follow that URL to read the substantive terms. Amendment filings share the same target/bidder/file_number as the original offer; use file_number to group an amendment chain. Pure-publisher posture: KeyVex does not derive 'likely to close' or 'expected premium' signals. The data here is what was filed, no more.

Query parameters

accession_numberstring

EDGAR accession number (e.g., '0001140361-26-020397'). Direct doc lookup, fastest path.

target_tickerstring

Target company ticker (e.g., 'KZR'). For SC TO-T this is the company being bid for; for SC TO-I this is the company buying back its own shares (target == bidder).

target_cikstring

Target's SEC CIK (10-digit zero-padded). Use when ticker is ambiguous (multiple share classes).

target_namestring

Case-insensitive substring against target_name. Useful when ticker isn't known (e.g., private companies in TO-T filings).

bidder_cikstring

Bidder's SEC CIK. Find all tender offers by a particular acquirer.

bidder_namestring

Case-insensitive substring against bidder_name. Bidders in SC TO-T are often private SPVs ('2025 Acquisition Company, LLC') — use this to find them by issuer / parent name.

form_type'SC TO-T' | 'SC TO-T/A' | 'SC TO-I' | 'SC TO-I/A'

Exact form match. Useful for narrowing to amendments only ('SC TO-T/A') or original offers only ('SC TO-T').

When true, restricts to SC TO-T family (third-party offers). Default false.

issuer_onlyboolean

When true, restricts to SC TO-I family (issuer buybacks). Default false.

exclude_amendmentsboolean

When true, drops /A amendment filings. Default false (amendments included).
