## 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-social-trading-event-feed-5675b1f9
```

Example prompt: Pull the latest 50 events from the FOMO social trading feed, filtered to just large_buy and multi_user_buy types, so I can see which tokens FOMO traders are piling into right now.

## When to prefer this

Use this endpoint when you need a real-time or near-real-time stream of social trading activity from FOMO traders — large trades, coordinated buys/sells, new listings, and profit milestones. Prefer it over token-specific endpoints when you want a broad cross-token signal stream rather than data about one specific token.

## Known failure modes

- Invalid cursor value returns an empty feed or error
- Unsupported event type string in `types` param silently returns no matching events
- Requesting limit > 100 returns a validation error
- Stale cache miss may cause slight delay on first fresh fetch
- Network timeout if the feed is momentarily unavailable

## How this service works

The event feed FOMO shows its users: large buys and sells, several traders buying or selling the same token, new token listings, price since listing, new theses, trader profit milestones and smart-following signals. types= narrows it to some event types (FOMO always adds its pinned manual post); page back with cursor. Newest first, usually minutes old. Use as a stream of social trading signals and large trades by FOMO traders.

## Output

A JSON object with a `data.feed` array of event objects (newest first), each containing an event id, type, body with trade details (ticker, price, market cap, FDV, user handle, PnL, swap counts, etc.), and a `meta` object with a `nextCursor` for pagination.
