## 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-following-list-ac77fd92
```

Example prompt: Pull the first page of traders that the FOMO user 'cryptowhale88' is following — I need their handles, wallet addresses, and 24h PnL stats.

## When to prefer this

Use this endpoint when you need to enumerate the traders a specific FOMO user follows — for building social graphs, identifying signal sources, or collecting wallet addresses of influencers that a given trader tracks. Prefer over the followers endpoint when the direction of the relationship matters (who they follow, not who follows them).

## Known failure modes

- Unknown or non-existent handle returns empty data or 404
- Invalid cursor value causes pagination error
- Private profile may return restricted or empty follower data
- Rate limiting or payment failure returns 402 or 429
- Stale cache may return outdated following list if stale=1 is passed

## How this service works

The traders one FOMO user follows (their signal sources), with handle, id, wallet addresses and profile stats, one page at a time. Pass the returned nextCursor as cursor= for the next page; the list ends with an empty page (nextCursor null).

## Output

A paginated JSON object containing an array of followed user profiles — each with handle, user ID, wallet address, EVM address, follower/following counts, swap count, trade count, 24h PnL, verified and activated flags, clan badge info, and profile metadata — plus a nextCursor for retrieving the next page (null when the list is exhausted).
