## 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`):

Example prompt: Can you enrich these 10 Japanese company records with their public payroll and grant data using kasanegi — I need structured, clean output without having to scrape Japanese government sites myself?

## When to prefer this

Choose this endpoint when you need to enrich multiple Japanese entities in a single call rather than one at a time, saving on per-call costs and latency. Ideal when you have a list of Japanese companies, payroll queries, or grant lookups and want clean structured JSON without building scrapers against Japanese government websites. Prefer over single-entity endpoints when processing lists of 2 or more items.
