API reference

Every public surface, indexed. Four gRPC proto packages on grpc.robinhoodrpc.io:443, plus two HTTPS surfaces. All of them authenticate with the same x-api-key; see Authentication. Message-level schemas come from the protos themselves: reflection is enabled and the .proto files are provided (SDKs & protos).

gRPC packages

robinhoodrpc (QuickNode-compatible)

The broadest package: the multiplexed StreamData feed plus dedicated book and block services. Wire-compatible with QuickNode's Robinhood Chain streams, so existing stubs work unchanged.

Method	Type	Carries	Docs
Streaming/StreamData	bidirectional	One subscription, six surfaces by `stream_type`: TRADES, ORDERS, BOOK_UPDATES, TWAP, EVENTS, BLOCKS.	Choosing a stream
Streaming/Ping	unary	Health check that echoes the request count.	Operations
OrderBookStreaming/StreamL2Book	server-streaming	Aggregated book by price level, 1–100 levels, never crossed. Snapshot, then one update per block.	L2 order book
OrderBookStreaming/StreamL4Book	server-streaming	Full order-by-order book with owners. Complete snapshot, then per-block diffs.	L4 order book
BlockStreaming/StreamBlocks	server-streaming	Raw L1 blocks live from connection time. QuickNode BlockStreaming and StreamData BLOCKS are live-only.	Blocks

robinhoodrpc_swaps.v1

The recommended trades surface: every executed fill as a flat swap record (Solana-swap-compatible schema) with wallet attribution, realized PnL, fees, and maker/taker role.

Method	Type	Carries	Docs
SwapStreaming/StreamSwaps	server-streaming	Executed fills, filtered server-side by `coins`, `wallets`, and `market_type`.	Trades & swaps

robinhoodrpc_btc_price.v1

Method	Type	Carries	Docs
BtcPriceStreaming/StreamBtcPrices	server-streaming	BTC last-trade price ticker. Minimal payload, available on Build and Scale.	BTC price ticker

robinhoodrpc_l1_gateway.v2 (Dwellir-compatible)

Dwellir-compatible service and message types, so stubs generated for Dwellir work unchanged. Height-based history is limited to the Scale 6-hour replay window; timestamp inputs resolve to current data where noted below.

Method	Type	Carries	Docs
Robinhood ChainL1Gateway/StreamBlocks	server-streaming	L1 blocks live, or from a recent block_height on Scale.	From Dwellir
Robinhood ChainL1Gateway/StreamFills	server-streaming	Executed fills live, or from a recent block_height on Scale.	From Dwellir
Robinhood ChainL1Gateway/StreamOrderbookSnapshots	server-streaming	Current full all-market snapshot once per second; Position is accepted but does not select history.	From Dwellir
Robinhood ChainL1Gateway/GetBlock	unary	Recent block fetch by block_height; latest when Position is unset or timestamp-based.	From Dwellir
Robinhood ChainL1Gateway/GetFills	unary	Recent fills fetch by block_height; latest when Position is unset or timestamp-based.	From Dwellir
Robinhood ChainL1Gateway/GetOrderBookSnapshot	unary	Latest full book snapshot; Timestamp is accepted but historical timestamp lookup is not promised.	From Dwellir

HTTPS surfaces

Surface	Endpoint	Coverage	Reference
Robinhood Chain JSON-RPC	https://rpc.robinhoodrpc.io	16 methods: reads, eth_getLogs, eth_sendRawTransaction, with example request/response each.	Robinhood Chain JSON-RPC
the equities REST API	https://api.robinhoodrpc.io/info	10 request types: market metadata, books, user state, fills, funding.	the equities REST API

A scope note worth repeating: the equities REST API CLOB orders (place/cancel) are submitted via Robinhood Chain's signed-action exchange API, not our RPC. The EVM RPC reads Robinhood Chain state and broadcasts Robinhood Chain transactions.

Field-level schemas

Per-stream message fields, semantics, and sample payloads live on the stream pages (trades, L2, L4, …); archive raw captured table schemas on historical schemas. The protos remain the source of truth; when in doubt, grpcurl describe the service.
