# IPO Calendar API > The live pipeline of US stock-market initial public offerings, served from Nasdaq's public IPO calendar — no key, nothing cached. This is the deal flow of companies going public, the data IPO investors and traders watch. The priced endpoint returns the IPOs that have just priced and begun trading, each with the ticker, company, exchange, offer price, shares offered, pricing date and total deal size. The upcoming endpoint returns the IPOs expected to price soon, with their price range and expected date — the near-term pipeline. The filed endpoint returns companies that have newly filed to go public, the earliest signal of a coming listing. The calendar endpoint returns the whole month in one call — priced, upcoming and filed — with counts. Any month back through the archive can be requested, and with no month it returns the current one. Everything is live from Nasdaq, nothing stored. This is the IPO-pipeline layer for any trading, investing, screener or finance app. Distinct from stock-quote and earnings APIs — this is the calendar of companies coming to market: priced, upcoming and freshly filed offerings. 4 endpoints, no key on our side. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
