Build the Axiom for Robinhood Chain
Robinhood Chain (chainId 4663) is the most active chain in FOMO's feed. This is the data layer for building an Axiom-style memecoin terminal on it: leaderboards, handle-to-wallet resolution, theses, token boards, and the realtime WebSocket.

Robinhood Chain (chainId 4663) is the most active chain in FOMO's feed, and it now has the kind of attention Solana had when the first memecoin terminals appeared. Axiom set the bar for what a memecoin terminal feels like: one screen that ranks traders and tokens, shows a wallet's real history, and streams fills as they happen. This is the data layer for building that same thing for Robinhood Chain, using only real FOMO API endpoints.
Rank the traders and the tokens
Two boards drive the front page. The trader leaderboard ranks by fomo.family's PnL figure, with the wallets attached so you can check the ordering:
curl "https://api.fomoapi.io/v2/leaderboard/30d?limit=50" \
-H "authorization: Bearer YOUR_API_KEY"
The token board is what FOMO users are actually trading right now:
curl "https://api.fomoapi.io/v2/leaderboard/tokens/trending?limit=25" \
-H "authorization: Bearer YOUR_API_KEY"
Each token row carries token{name,symbol,address}, priceUsd, change24h, marketCapUsd, volume24hUsd, and fomoBuyers, which is enough to render a live board.
Resolve a handle to a wallet and PnL
A terminal needs to turn a name into an address and a track record in one call:
curl "https://api.fomoapi.io/v2/users/<handle>" \
-H "authorization: Bearer YOUR_API_KEY"
You get wallets{solana,evm} (the evm address is the trader's Robinhood Chain wallet), pnl:{24h,7d,30d,all}, holdings, topTokens, and accountAgeDays. Follow it with /v2/users/<handle>/positions for the entry and exit history, where each trade is labeled chain:"robinhood", chainId:4663.
The why behind each trade
Prices tell you what happened; theses tell you why. Pull the reasoning traders attached to their Robinhood Chain trades:
curl "https://api.fomoapi.io/v2/thesis?chain=robinhood&limit=50" \
-H "authorization: Bearer YOUR_API_KEY"
For a single coin's page, /v2/thesis/token/<mint> returns every thesis written about that token, each with handle, text, tradeUsd, likes, and replies.
Stream it live
The last piece is a live tape. Open the WebSocket scoped to chain 4663:
new WebSocket("wss://api.fomoapi.io/ws/alerts?chain=robinhood&key=YOUR_API_KEY");
// { type:"welcome", realtime, delaySeconds } then live { type:"alert", trader, token, tokenAddress, usdValue, chain, ... }
The stream is realtime on any paid plan; a free key streams realtime for its first 7 days, then drops to a 15-second delay. Filter further with ?type=buy|sell|thesis or ?token=<symbol|address>.
That is the whole surface: two boards, handle-to-wallet resolution, theses, and a live feed. For who is actually worth putting at the top, see Top Robinhood Chain Traders on FOMO, and to catch coins early, How to spot Robinhood Chain runners before they run.
