# Get today's risk-free rates (`valuation_rates`)

Today's risk-free curve and its recent average from the Bundesbank, the ECB or the US Treasury, as decimals.

The risk-free curve for the cost of capital: each maturity's latest rate and its average over recent days (90 by default), from the Bundesbank's Svensson curve for Federal securities (the IDW base rate's starting point), the ECB's AAA euro area curve, or the US Treasury's par yields. As decimals, ready for valuation_wacc.

Price: Free up to 1,000,000 reads a month for the whole account, then $0.50 per 10,000 reads. A call that fails costs nothing.

## Use it when

Before working out the WACC, to set the risk-free rate.

- For the cost of capital itself, use [valuation_wacc](https://conecto.chat/tools/valuation/valuation_wacc.md).

## Say this to your agent

> What is the German risk-free rate for 10, 20 and 30 years right now, and over the last three months?
