## 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`):

```sh
zero fetch --capability x4o2-fomo-trader-followers-e9e1ad9e
```

Example prompt: Pull the full follower list for FOMO trader handle 'cryptowhale' — I want each follower's handle, their wallet address, swap count, and 24h PnL so I can find active traders in that circle.

## When to prefer this

Use this endpoint when you need to map the social graph around a specific FOMO trader — specifically their audience (followers), not who they follow. Prefer this over the 'following' endpoint when the goal is audience analysis, influence gauging, or finding traders who look up to a specific user. Best for on-chain wallet discovery via social connections.

## Known failure modes

- Unknown or non-existent handle returns null data or empty users array
- Private accounts may suppress follower details
- Stale cache returned when background refresh is pending
- Rate limiting or payment failure (402) if USDC balance is insufficient
- Malformed handle in path parameter returns 4xx error

## How this service works

The FOMO users following one trader, with each follower's handle, id, wallet addresses and profile stats. Use to gauge a trader's audience and find connected traders.

## Output

A list of FOMO user objects, each containing: user handle, numeric ID, EVM wallet address, follower and following counts, swap count, trade count, 24h PnL, total volume, verified and activated status, profile picture URL, display name, bio, account creation date, and referral status. Also includes metadata about cache age and data source.
