Rate data and downloads

Use the same public rate feeds that support YieldFinder's comparisons.

Read the dates and units

Individual records can have different observation dates. A feed retrieval time is not a new provider review. Unavailable or suspect observations may be withheld; missing values are not zero yields.

Savings and CD APYs, fund income yields and Treasury par yields are different measures. Keep product type, source URL and date alongside any value you reuse.

Using these feeds

The feeds are public and cached. Avoid polling more often than every five minutes, handle missing fields, and verify official provider terms before making a financial decision. There is no guaranteed update time or availability commitment.

If you share a chart or analysis using these feeds, please link to YieldFinder and identify the observation dates so readers can check the context.
