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.

Pixel-art blockchain rail carrying linked blocks and early trading signals through a digital city.

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.

FAQ

What data do I need to build a Robinhood Chain trading terminal?
Four things, all from the FOMO API: ranked boards (GET /v2/leaderboard/{window} for traders and GET /v2/leaderboard/tokens/trending for tokens), handle-to-wallet resolution with PnL (GET /v2/users/{handle}), the written theses behind trades (GET /v2/thesis), and a realtime trade feed (the WebSocket at wss://api.fomoapi.io/ws/alerts). Scope anything to chain 4663 with chain=robinhood.
How do I get a trader's Robinhood Chain wallet?
Call GET /v2/users/{handle}. The response includes wallets.evm, which is the trader's Robinhood Chain wallet (the same EVM address works across EVM chains), along with their Solana wallet, verified multi-window PnL, and holdings.
Is the leaderboard ranking gameable?
No. Leaderboard PnL is fomo.family's own figure, with each row carrying the real wallets so you can check the trades. You can confirm any row by reading that trader's trades with GET /v2/users/{handle}/positions.
How do I stream live trades for chain 4663?
Open a WebSocket to wss://api.fomoapi.io/ws/alerts?chain=robinhood. You receive a welcome message, then live alert events carrying the trader, token, token contract, and USD size. It is realtime on any paid plan; a free key is realtime for its first 7 days, then 15-second delayed.
Is this affiliated with Robinhood or FOMO?
No. FOMO API is an independent, unofficial data layer for fomo.family and is not affiliated with, endorsed by, or sponsored by FOMO or Robinhood.
