FXMacroData is a macro data API built for FX: releases, forecasts, policy rates, bond yields and positioning across 26 currencies, with point-in-time history. It is wide. If your trading is the US print, the Treasury auction and the curve, you want that one market read in depth, at a lower price to start.
FXMacroData wins on breadth and volume: 26 currencies, 1,000,000 requests a month on its Individual plan at $50 a month, point-in-time history, SSE streams and webhooks. Helious is narrower and costs less to start, with a free key, $14.99 on Starter and $39.99 on Pro. For that it reads the US market in depth. Every US release is scored in standard deviations on print, Treasury auctions arrive within seconds with the tail, the bidder split and a verdict, the news feed is scored, and Pro includes the terminal as well as the API. FXMacroData does not state auction results or a standard deviation score on its site.
