That's why I'm doing this with an ESP32 instead of an RPi.

The ESP32 has the builtin capability to deep sleep and only draw a few uA of current. In addition, WaveShare offers existing micropython libraries, so it's easy to just flash an ESP32 board with micropython, get your data from an API, format it and go to sleep after displaying it. There are lots of boards with onboard LiIon management, this this setup is very easy to do.

The Raspberry Pi Pico W might be an alternative these days. Of course with only a couple Cortex M0 cores and 264KB RAM running JavaScript would be less than feasible, but rendering a pure black and white framebuffer for a e-ink screen should work OK.
