print(r.json())What is 424B4?
Rule 424(b)(4) covers the final prospectus that adds pricing information previously omitted under Rule 430A. For an IPO, the 424B4 is the document with the actual offering price, number of shares, underwriting discount and net proceeds, filed right after pricing.
That makes 424B4 the cleanest record of completed IPOs and priced follow on offerings. SecFeed's IPO API reads the cover terms so you get shares, price, ticker, exchange and underwriters without parsing the prospectus.
Issuers whose registration statement went effective without final price information under Rule 430A, mainly IPO issuers.
No later than the second business day after pricing or first use.
