Questions
How do I get access?
FRED is part of Apizie Finance, a premium add-on from $49 a month that runs next to any Apizie plan. See /finance#pricing.
Is this the official FRED data?
Yes. Apizie calls Federal Reserve Bank of St. Louis's own public API (api.stlouisfed.org) and returns the result as JSON. Every response links the official page and API URL it came from. Apizie is independent and not affiliated with or endorsed by the SEC, the Federal Reserve, the ECB, the U.S. Treasury, GLEIF or the World Bank.
How do I cite FRED data from Apizie?
Use the source block in the response: source.attribution is a ready-made line, source.url is a page a reader can open, and source.retrievedAt is when the data was fetched.
What licence applies?
Free to use under the FRED API Terms of Use; series marked as copyrighted by a third party are excluded. Read the publisher's terms at https://fred.stlouisfed.org/docs/api/terms_of_use.html. These sources are part of Apizie Finance, and your Finance plan sets how you may use the data: inside your company on Finance Starter, in your own product with attribution on Finance Growth and Business. Redistribution needs an Enterprise agreement.
Can I get notified when FRED publishes something new?
Yes, with Apizie Finance. Data alerts send a signed data.changed webhook and a dashboard notification when the source updates.
