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

```sh
zero fetch --capability taiwan-market-signal-latest-company-signal-8d72e877

## When to prefer this

Use this endpoint when you need the latest combined market, revenue, and disclosure signal for a specific Taiwan-listed company by its numeric stock code. Prefer this over generic financial APIs when you specifically need Taiwan TWSE or OTC company data with official monthly revenue disclosures integrated into a single signal call.
