CLI

The CLI ships in the same package:

export ENTITY_API_KEY="YOUR_API_KEY"

entityml health
entityml polymarket market-data \
  --condition-id 0x0008043c3ed513ecff7ee64380fc943dc73eb3dfb6674f281149efe4769f7515 \
  --date 2026-02-13

The legacy poly-storage command is still installed as a compatibility alias.
