# Returns SEC Schedule TO filings — public tender offer disclosures

`GET /v1/tender-offers`

## Request

- Base URL: `https://api.keyvex.com`
- URL: `https://api.keyvex.com/v1/tender-offers`
- Auth: API key in header `x-api-key`

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.
