# Running Hundreds of API Calls to Pull NAV History, One Scheme Per Call? Batch 50 Into One.

Running hundreds of API calls to pull NAV history, one scheme per call?

You can batch 50 schemes into a single call, which turns two hundred funds into four calls, and if you want everything there is a single download of the full database, April 2006 onward. Same data, far less waiting.
