## 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 to programmatically verify a Twitter/X follow relationship between two specific accounts, such as for gated access, community verification, or social proof workflows. Prefer this over scraping or manual checks when you need a reliable, paid API-backed answer at $0.05 USDC per call.

## Known failure modes

- Invalid or non-existent username returns error or false result
- Twitter API rate limiting causing delayed or failed response
- Private/suspended account may return indeterminate result
- Payment failure (insufficient USDC balance) blocks the request
- Network timeout from the hosted service on Render
