We are now supporting Ethereum DEX trading data on our GraphQL APIs. You can get DEX trades, OHLC, trading volume, and other DEX related data for more than 18 Ethereum DEX protocols such as Uniswap, Balancer, Kyber, 0x, IDEX, etc.
Before we show some examples, here are a few important things to note:
- GraphQL is an API query language, read this create your first GraphQL query.
- Read this to learn how to call GraphQL queries as APIs programmatically.
- GraphQL queries are highly flexible; therefore, you can change the following queries based on your needs or create a new one by following our GrpahQL schema (Available on our playground.)
- You can test the following GraphQL queries on our Playground.
- Our GraphQL endpoint is — https://graphql.bitquery.io/
- Our GraphQL APIs support more than 20 blockchains. Check out our blog to see more examples.
- You can also check DEX data on our blockchain explorer, here, here, and here.

Latest trades of a specific currency pair on a DEX protocol
Now, if you want the latest trades for a specific currency pair, use the following query. We are getting the latest trade for USDT — WETH currency pair on Uniswap protocol (V2) in this query.
As you can see, you need to pass the smart contract address for the tokens to get the latest trades for them.
Here we are passing 0xdac17f958d2ee523a2206206994597c13d831ec7 for buyCurrency which is the USDT token’s address. And, 0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2 for sellCurrency which is the WETH token’s address.

OHLC data for currency pair on DEX
Open-high-low-close(also OHLC) data used to create an OHLC chart, which illustrates movements in the price of a financial instrument over time.
Using the following query, you can get the OHLC data for any currency pair for any DEX protocol.
In this query, we are getting USDT-WETH currency pair’s OHLC data for 5 minutes interval.
We support the following time interval units.
- second
- minute
- hour
- day
- month
- year
Using the above units, you can create any type of chart candles. For example
- 5-minute interval
timeInterval {
minute(count: 5)
}
- 1-day interval
timeInterval {
day(count: 1)
}
Here is the query to get 5-minute OHLC data for the USDT-WETH currency pair on Uniswap protocol.

Monthly DEX trading volume for a specific Token
The following query gives us aggregated trading volume for a specific token on all DEX protocols. For example, in the query below, we are getting the trading volume for USDT token on all DEXs.
Note: We are passing the USDT token’s contract address, 0xdac17f958d2ee523a2206206994597c13d831ec7 to get the data in the query below. Our queries do not recognize token names. They only recognize smart contract addresses. So if you want to get trading volume for any other token, use the contract address for that token.

"ethereum": {
"dexTrades": [
{
