# x4o2 FOMO Developer Wallet Data

> x4o2 FOMO Developer Wallet Data is a paid API for AI agents from fomo.x4o2.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-28).

Returns the deployer wallet(s) FOMO associates with a token, their FOMO profiles, and their current holdings and trading activity in that token — used as a dev-wallet and rug-risk signal.

## 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-developer-wallet-data-7d2e65c5
```

Example prompt: Pull the FOMO developer panel for the Solana token at mint address EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v — I want to see the deployer wallets, their FOMO profiles, and how much of the token they still hold.

## When to prefer this

Use this endpoint when you need to assess developer/deployer risk for a specific token — particularly to check if devs still hold large positions (rug-pull signal), whether the deployer has a known FOMO identity, or to correlate on-chain wallet behavior with a social trading profile. Prefer this over generic on-chain explorer APIs when you want FOMO-specific social identity linkage alongside holdings data.

## Known failure modes

- Token address not found on the specified chain — returns null data
- Chain identifier is invalid or unsupported — request rejected
- No developer wallet associated with this token in FOMO's data — devHoldings returns empty or null
- Stale cache served when upstream data is unavailable — check meta.source field
- Rate limiting or payment failure via x402 protocol — HTTP 402 response
- Network timeouts for newly deployed tokens not yet indexed

## How this service works

FOMO's developer panel for a token: the deployer wallet(s) FOMO links to the token, their FOMO profile where one exists, and their current holdings and trading in it. Use as a dev-wallet and rug-risk signal.

## Output

Returns a data object containing the network ID, token address, and devHoldings array — each entry includes the deployer wallet address(es) FOMO links to the token, the associated FOMO user profile (if one exists), and their current token holdings and recent trading activity. Also includes freshness metadata (observedAt timestamp, age in milliseconds, and cache/fresh/stale source indicator).
