CRIUS

Historical data API

Robinhood Chain historical data API

Crius indexed Robinhood Chain from block 0, so trades, candles, holders, launches and pools are queryable for any point in the chain's history without running an archive node or an indexer of your own. Every row carries its block and finality, and the index follows reorgs so history stays consistent with the chain.

What you get

Built for Robinhood Chain, not bolted on

  • From block 0

    The whole chain was backfilled from genesis: every trade, transfer, pool and launch since the first block.

  • Point-in-time queries

    Holders and prices at any block, timestamp, market cap crossing or lifecycle event.

  • Finality on every row

    latest, safe or finalized, plus meta.safe_block and meta.finalized_block in every response.

  • Reorg handling

    The index rolls back and re-applies reorged blocks; streams send a reorg message and re-send removed events flagged removed: true.

  • No node, no ETL

    Skip the archive node, the trace backfill and the decoding pipeline: the data is already indexed and joined.

  • Verified balances

    Holder balances are rebuilt from transfers and checked against the chain.

Questions about the Historical data API

How far back does Crius history go?

To block 0 of Robinhood Chain. Trades, transfers, pools, launches and holders were backfilled from genesis.

How do you handle reorgs?

Each row has a finality (latest, safe, finalized). When the chain reorganises, the index rolls back and re-applies the affected blocks, and the stream announces the reorg and re-sends removed events.

How does this compare to Dune or an RPC?

Dune is a SQL warehouse for analysis; an RPC gives raw state and logs you must decode yourself. Crius serves the decoded, joined result as an API built for applications. See the RPC vs indexer comparison.

Do I need an archive node?

No. Crius runs its own archive nodes and indexer; you query decoded, joined data over REST. You'd only need your own node to send transactions.

Can I get the state of a token at a past block?

Yes: holders and their values with /holders/snapshot?at=block:N, price history with /candles, and trades with to_ts.
