## 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 fomo-token-holders-leaderboard-b6cc9105
```

Example prompt: Who are the biggest FOMO holders of the token at address 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU on Solana, and what P&L and thesis have they posted?

## When to prefer this

Use this endpoint when you need social-layer holder analysis — specifically for tokens traded on the FOMO platform — and want to combine on-chain position data (amount, P&L, cost basis) with social signals (FOMO handle, thesis text, developer flag). Prefer this over raw on-chain holder queries when the social identity, posted conviction thesis, and trader reputation context matter. Not suitable for comprehensive on-chain holder distribution across all wallets, as it only covers FOMO platform users.

## Known failure modes

- Unknown or unsupported chain identifier returns an error or empty result
- Invalid or non-existent token address returns 404 or empty holders list
- Token has no FOMO traders (all on-chain holders, none on FOMO platform) returns empty array
- Stale cache with maxAge=0 may incur higher latency or a timeout
- Rate limiting or payment failure (x402) if USDC balance is insufficient

## How this service works

The FOMO users holding the most of a token: each holder's FOMO handle and id, token amount, position value, cost basis, realized and unrealized P&L, hold time, developer flag and their posted thesis. Covers holders who trade on FOMO, not every on-chain wallet. Use for social and holder analysis of a token.

## Output

An array of the top FOMO token holders, each containing the holder's FOMO handle and user ID, the amount of the token they hold, the current position value, their cost basis, realized and unrealized profit/loss, how long they have held the position, a boolean developer flag, and the text of any thesis they posted when entering the trade.
