Well, those of you who are familiar with the SEC EDGAR database know that it is one of the least user-friendly websites on the internet. iEDGAR is designed to help you find the financial data you are looking for in a more straightforward way.
There are several things iEDGAR does different:
The API allows you to easily import data from iEDGAR into an application or spreadsheet using a url. There are currently two types of data available:
For an example of what is possible with the iEDGAR API and XBRL, check out this blog post by Nate Anderson.
The initial index of SEC filings was built up using the SEC's montly XBRL rss feed. Now iEDGAR checks the SEC's recent filings feed every 10 minutes and immediately adds any new filings and companies to the database.
The initial CIK to ticker mapping was taken from Rank & Filed and is now updated by sending the company name to the Yahoo Finance API. If a match is found, the returned ticker is checked against the EDGAR filings feed to see if this CIK / ticker match is actually correct. This data is also updated every 10 minutes.
At this time, no. You can use it freely without limitation. HOWEVERRRRR, please do not abuse this freedom, or I'll be forced to add a "speed limit".
