## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Use this endpoint when you need institutional/main-force capital flow data specifically for Chinese A-share stocks — particularly useful for retail investors wanting to verify smart money activity before entering a position. Prefer this over generic stock quote endpoints when the question is about capital flow direction and institutional participation, not just price.
