Your first
ZKsync call
The five busiest ZKsync pools by 24h volume, then the live price of WETH. Every row carries both token symbols, so there is no second lookup before you can read it.
Paste and run. A free API key lifts you to 100K requests a month.
# top ZKsync pools by 24h volume
curl "https://api.dexpaprika.com/networks/zksync/pools/search?order_by=volume_usd_24h&sort=desc&limit=5"
# live price for WETH
curl "https://api.dexpaprika.com/networks/zksync/tokens/0x5aea5775959fbc2557cc8789bc1bf90a239d9a91"Streaming: stop polling ZKsync
Open one SSE connection and we push token prices and per-block pool reserve deltas as ZKsync state changes, a push-based reserves feed you will not find at CoinGecko or DexScreener. Poll loops re-fetch unchanged state and still miss mid-block moves. With push, the only gap between on-chain state and your app is the network round-trip plus our block indexing.
# push: live WETH price ticks on ZKsync. One connection, no polling
curl -N "https://streaming.dexpaprika.com/sse/prices?chain=zksync&address=0x5aea5775959fbc2557cc8789bc1bf90a239d9a91&method=token_price"

Questions about the ZKsync DEX API
Which ZKsync DEXes does the API cover?
3 ZKsync DEXes including Pancakeswap v3, SyncSwap, zkSwap, with 120+ active pools across them, as of 2026-10-09 01:09 UTC.
How fresh is the ZKsync data?
Data updates every ZKsync block. Paid plans get it in real time; on the free plan a response can run a short way behind the chain. SSE streams push changes as they happen, so there is no polling interval between your app and ZKsync chain state.
Do I need an API key for ZKsync data?
For anything past a first test, yes. A free API key takes under a minute, needs no credit card, and covers 100K requests per month on every chain, with every endpoint except pool transactions and token OHLCV: pool transactions start at Dev and token OHLCV at Pro. Dev ($30/mo) raises that to 500K, and Pro ($99/mo) lifts the ceiling to 5M requests.
How do I get a ZKsync token price with the API?
GET /networks/zksync/tokens/{address} returns the live USD price with 24h volume and liquidity in one call. For portfolios, /networks/zksync/multi/prices returns batched prices for up to 10 tokens per request.
Does streaming work for ZKsync?
Yes. SSE streams at streaming.dexpaprika.com push ZKsync token prices (/sse/prices) and per-block pool reserve deltas (/sse/reserves, needs an API key). That is a push-based reserves feed you will not find at CoinGecko or DexScreener.
What does the ZKsync DEX API cost?
The free tier includes 100K requests per month with a free API key, no credit card, on every chain, with every endpoint except pool transactions and token OHLCV: pool transactions start at Dev and token OHLCV at Pro. Dev is $30/mo for 500K requests, and Pro is $99/mo for 5M requests with priority support.
