Free IPO Pipeline API

The EDGAR filings that mark each stage of a US listing as JSON: registration statements (S-1, F-1) and their amendments, final pricing prospectuses (424B4), SEC effectiveness notices (EFFECT) and withdrawals (RW), with a flag for whether the filer is already listed.

Response shape

Every endpoint returns the same JSON envelope: { data, updatedAt, source, docs, license, attribution, meta }. In meta, source names who publishes the data and sourceAttribution is the credit line to show with it. The data field is an array of records with these fields:

Field	Type	Description
accessionNo	string	EDGAR accession number
formType	string	S-1, S-1/A, F-1, F-1/A, 424B4, RW or EFFECT
cik	string	Filer CIK, ten digits
companyName	string	Filer name as on EDGAR
filedAt	string	EDGAR filing date
listed	boolean	Filer is on the SEC's listed-ticker table today; a company that has priced is listed by now
firstRegistration	string \| null	Earliest S-1 or F-1 on file for the filer; a 424B4 weeks after it is an IPO pricing
offeringAmount	number \| null	Always null; offering amounts are not included

EFFECT and RW notices appear for companies with an S-1 or F-1 on file.

Numeric fields typed string in the table carry exact decimals; parse them with your language's decimal type.

Frequently Asked Questions

How do I get only real IPOs?

Ask for S-1 and F-1 with new=1, then watch the same CIKs for a 424B4. A 424B4 from a CIK that was not listed when it filed its S-1 is an IPO pricing.

How fresh is it?

Updated every 30 minutes on business days.

What are the rate limits?

10 requests a minute per IP without a key and 30 a minute with a free account key, with at least six months of history.
