CRIUS

Robinhood Chain API

The Robinhood Chain API for prices, trades, holders and launches

Crius is a Robinhood Chain data API: real-time and historical token prices, OHLCV candles, DEX trades, holders, launchpads, wallet analytics and token security over REST and WebSocket, indexed from the chain's first block. It has a free plan with 1,000,000 credits a month, and core endpoints work without an API key.

In one paragraph

What a Robinhood Chain API gives you

Robinhood Chain is an Ethereum-compatible layer 2 (Arbitrum Orbit, chain ID 4663) where tokenized stocks, stablecoins like USDG and launchpad tokens trade on Uniswap v2, v3 and v4. A node's JSON-RPC lets you read raw state and logs. A data API does the indexing for you: it decodes every swap and transfer, prices it, keeps holders and pools up to date, and serves the result over HTTP and WebSocket.

Crius runs its own archive nodes and indexer for Robinhood Chain only, so the endpoints answer the questions developers on this chain actually ask, from token prices to Pons bonding curves.

Every response is {data, meta}; meta.block is the block it reflects and meta.lag_ms how far behind the chain head it is.

History

How it works

From the chain to your app

  1. 1
    Robinhood Chain

    Arbitrum Orbit L2, chain ID 4663, ~100 ms blocks

  2. 2
    Our archive nodes

    Full history and traces, no third-party RPC in the path

  3. 3
    Indexer

    Decodes swaps, transfers, launches, hooks and locks; prices every trade

  4. 4
    Crius API

    REST and WebSocket, block-stamped, finality-aware

Data is typically served well under a second after a block is produced. Each row carries its finality (latest, safe or finalized), and when the chain reorganises the index rolls back and re-applies the affected blocks. More on history and reorgs.

Why Crius

What makes a good Robinhood Chain API

  • From block 0

    The whole chain backfilled from genesis: every trade, transfer, pool and launch. History and live data come from the same index.

  • The real trader

    Swaps through routers, Relay solvers and ERC-4337 bundlers are attributed to the wallet whose balance changed.

  • Robinhood Chain native

    Pons, Flap.sh, Bankr, Long.xyz and King of the Markets lifecycles; Uniswap v4 hooks decoded into risk flags; tokenized stocks priced on-chain.

  • Answers, not raw logs

    Holders at any block, top traders by PnL, honeypots and realized tax, bundles and bubble maps: one call each.

  • Fresh and honest

    Every response carries the block it reflects and its lag; streams flag latest, safe and finalized and replay reorged events.

  • Free to start

    1M credits a month on the free plan, keyless core calls, and plans paid on-chain in USDG or ETH.

Robinhood Chain API questions

Is there a free Robinhood Chain API?

Yes. Crius has a free plan with 1,000,000 credits a month and 10 requests per second, no card required, and core endpoints (prices, token profiles, pools, trades, candles, search, stats, security) also work without any API key at 2 requests per second.

Should I use an RPC node or an indexed API?

An RPC gives you raw state and logs; you decode, join, price and store them yourself, and handle reorgs. An indexed API like Crius gives you the finished answers. Use RPC to write to the chain or for data no index models; use an indexer for market data, history and analytics.

Which DEXs and launchpads are covered?

Uniswap v2, v3 (all fee tiers) and v4 with hooks, plus the launchpads Pons, Flap.sh, Bankr, Long.xyz and King of the Markets, with bonding curves and graduations.

Can I get data in real time?

Yes, over WebSocket: trades, prices, live candles, new pools, launches, graduations, liquidity and tax changes, and wallet activity, pushed as each block is decoded, with resume after reconnects and reorg handling.

What is the best Robinhood Chain API?

It depends on what you build. To send transactions you need an RPC provider; for SQL analysis, a warehouse like Dune; for multi-chain wallet data, a multi-chain API. For application data on Robinhood Chain itself (prices, candles, trades, holders, launchpads, PnL and token safety, live and historical), Crius is built specifically for it. Our comparison page lays out the options with sources.

How far back does the data go?

To block 0. Crius backfilled Robinhood Chain from genesis, so trades, candles, transfers, holders, pools and launches cover the chain's entire history.

Does it cover tokenized stocks?

Yes. Stock tokens such as TSLA and NVDA are indexed like any token: on-chain prices, candles, trades and holders.
