## 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

Choose this endpoint when you need social media share-of-voice or brand social signal data specifically tied to a product category, scoped to TikTok and/or Instagram. Prefer it over generic social listening tools when you need category-contextualized brand comparisons, time-windowed rollups, and the ability to filter organic vs. paid posts. Best suited for e-commerce and retail brand intelligence use cases on the Syntalic platform.

## Known failure modes

- Invalid or unrecognized category slug returns an empty result set or error
- Requested time window not yet published returns an error or empty response
- Brand name not found in corpus returns zero or empty results
