...and I can answer my own question, but I'll post it here in case it saves anyone else some time:
The JSON API that now works came from inspecting this page <https://institutional.vanguard.com/investments/product-details/fund/1470>, and searching through the XHRs for the NAV price listed. This came up (no headers seem to be needed): https://eds.ecs.gisp.c1.vanguard.com/eds-eip-distributions-service/price/daily-nav-history/7743.json?start-date=2021-10-08&end-date=2021-10-09 Where "7743" is the FIID (fund ID? IDK), and while I don't remember where I originally got 7743, I think it was in the malformed OFX export XML from logging into my Vanguard portal.
