Measured two ways on production: FOMO trades reach the on-chain stream about 3.5 seconds before the app feed, not 15. The bigger edge is every fill, with real sizes.

Guides
Resolve Any FOMO Handle to a Wallet
Turn a FOMO handle into both on-chain wallets, Solana and EVM, in a single API call, along with PnL and account age. A short walkthrough.
Product
FOMO Does Not Have an API. This Is the One That Does.
A recurring complaint about FOMO is that it has no public API, so the data cannot be pulled programmatically. This is the independent API that resolves it.
Data
FOMO Removed Twitter Links. Get a Trader’s Real X Account Anyway.
FOMO removed the X links from profiles, so you can no longer tell if a handle is the Twitter account it claims to be. The API still resolves the connection.
Product
The Social Trading Aggregator Everyone Keeps Asking For
Traders keep asking who is building a single aggregator for social trading terminals. Whatever it looks like, it needs a data layer. Here is the FOMO half of it.
Data

A fresh FOMO account holding a big position is a different risk than a two-year veteran. FOMO does not show account age, but the API returns it for any handle.
Data
A FOMO Trader's Real Track Record: 24h to All-Time
Judging a trader on one time window is misleading. The FOMO API returns PnL across 24h, 7d, 30d, and all-time for any handle, plus hold time.
Data
Who Actually Holds This Token? A Smart-Money Holder List
Turn a token address into a list of named FOMO traders who hold it, a smart-money holder signal instead of an anonymous list of addresses.
Data
What Tokens Are FOMO Traders Actually Buying
The token boards FOMO traders are actually trading and holding right now, over a plain API: trending, most-held, and graduated.
Data
The Identity Layer: From Anonymous Wallet to Named Smart Money
The chain shows an anonymous wallet. The FOMO API resolves it to a named trader, their real wallets on both chains, their Twitter, and PnL. Why identity is the crown jewel, and the endpoints that return it.
Data
FOMO Notifications as a Trading Signal
FOMO's push notifications are its curation layer: what it amplifies to thousands at once. Why that is a trading signal, and exactly which parts of it an API can still give you.
Data
Top FOMO Traders' Real Wallets, Ranked by PnL
The real on-chain wallets of FOMO's top traders by all-time PnL, on Solana and EVM. Not the empty signer wallets FOMO shows on profiles.
Use Cases

Open a per-trader WebSocket at wss://api.fomoapi.io/ws/alerts and receive only that trader’s buys, sells, and theses in real time. Build a copy-trading bot.
Wallet Resolution
FOMO Won't Connect a Trader to Their Wallet or Their X Account. We Do.
FOMO shows a handle but not the trader's real on-chain wallet or X account. Our API resolves both from one call to GET /v2/users/{handle}.
Wallet Resolution
The Real On-Chain Wallet Is the Fastest Copy-Trading Data Source
An app feed is a downstream copy of what already happened on-chain. Resolve a trader's real wallet and stream their swaps straight from the source.

Why Thesis Data Is a Game-Changer for Copy Trading
Trader numbers tell you what happened. Thesis data tells you why. Here is why the reasoning behind each trade is the real edge for copy trading and research.
Thesis Data
FOMO Thesis Data: The Why Behind Every Trade, in One Endpoint
