# Data alerts

Watch an official source and get a signed `data.changed` webhook and a dashboard notification when it publishes something new.

| Alert | Fires when |
| New SEC filings | A company files a new form (optionally only some forms, e.g. 10-K, 8-K) |
| New FRED observation | A FRED series gets a new or revised latest value |
| New Treasury yield curve | The U.S. Treasury publishes a new daily par yield curve |
| ECB policy rate change | The ECB changes a key interest rate |
| New World Bank value | An indicator gets a newer year for a country |

Data alerts are part of [Apizie Finance](/finance). Create them in [Dashboard → Data alerts](/dashboard/alerts). Finance Starter includes 5, Growth 50 and Business 200. Alerts are checked about once a day and whenever you press **Check now**; checks do not use your request quota.
