Hello! Tradier Brokerage operation does support fixed income securities, but we currently don't offer this through our website or APIs. I noted that you'd be interested in something like that.

Some data goes back as far as 2009 others as soon as January of this year. It also depends a bit on the interval granularity you're looking for.
