The Klaytn data API for Kaia's consumer apps.
You shouldn't have to run a Kaia node, babysit an archive node or stitch together raw JSON-RPC just to answer a simple question. We've already indexed DEX trades, token transfers, contract calls and events. Each is one query away.
query { ethereum(network: klaytn) { dexTrades( options: {desc: "block.height", limit: 10} date: {is: "2026-10-08"} protocol: {is: "PancakeSwap v3"} ) { block { height } exchange { fullName } buyCurrency { symbol } sellCurrency { symbol } buyAmount tradeAmount(in: USD) } } }
JSON-RPC was never meant to answer the questions you actually have.
Ask "what did this wallet ever do?" and raw Kaia hands you an archive node, a pile of ABIs to decode by hand and thousands of chained eth_getLogs calls. We've already done that work, so you can skip straight to the answer.
Two ways to get Klaytn data: GraphQL queries or a bulk cloud export.
Query Klaytn data in GraphQL, or take it as a bulk cloud export.
The Klaytn DEXs we decode.
One dexTrades query covers every venue below. Filter by token, pair, pool, trader or protocol, then group the trades into OHLC candles, top traders or volume.
PancakeSwap v3-style poolsConcentrated liquidityPools built on PancakeSwap v3 code, forks included
Uniswap v2-style poolsAMMPools built on Uniswap v2 code, forks included

From ERC-20 transfers to decoded contract events, it's all behind a single endpoint — no node, no archive sync, no indexer to build. Every dataset except Coinpath® is available as complete history in the $150/mo data pack.

Each of these is a filter on the same indexed data, queried over GraphQL.
Find new Klaytn pools
Query PoolCreated events from a v3-style pool factory and poll for new ones. No node to run.
smartContractEvent: { is: "PoolCreated" }
Wallet history & PnL
Pull a wallet's transfers and trades, then work out balances and PnL on your side.
receiver: { is: "<wallet>" }
Build OHLCV price charts
Turn raw DEX trades into candlesticks per pair and interval, the kind of feed behind TradingView-style Klaytn charts.
timeInterval { minute(count: 5) }
