Uniswap on Arbitrum: DEX data API
Uniswap v2, v3 and v4 all run on Arbitrum, each from its own factory address, and the API lists each version as its own DEX. Pools, prices, OHLCV candles and individual swaps come back over REST, with streaming in preview.

Uniswap API questions
Do I need an API key to query Uniswap data?
A free API key is the place to start. It needs no credit card and works on every endpoint on this page: register one at console.dexpaprika.com. Current quotas are on the pricing page.
Which Uniswap version is a swap from?
Read factory_id on the transaction row: 0x1f98…f984 is Uniswap v3, 0x360e…fb32 is Uniswap v4 and 0xf1d7…bcf9 is Uniswap v2. Pool records carry dex_id directly: uniswap_v3 is Uniswap v3, uniswap_v4 is Uniswap v4 and uniswap_v2 is Uniswap v2.
How do I list only Uniswap pools on Arbitrum?
Call /networks/arbitrum/pools/search with dex_name=uniswap_v3, then with dex_name=uniswap_v4 and dex_name=uniswap_v2 for the other versions. Add order_by=volume_usd_24h to get the busiest first.
How fresh is the Uniswap data?
On the free plan, data can run a short way behind the chain. Paid plans serve it in real time. The figures on this page were read from the API at 2026-09-17 14:31 UTC.
What counts as one request?
One call is one credit, including a call that returns many rows. Batch endpoints bill per item. Each streaming update also counts as one.
Can I stream Uniswap swaps instead of polling?
Streaming over server-sent events is in preview. /sse/transactions pushes swaps on a pool or token as they land. Access is described in the showcase streams docs, and a running price stream is on the Arbitrum streaming page.
How do I send my key once I have one?
Put the key in the Authorization header on its own, with nothing in front of it.
Which host do I call?
api.dexpaprika.com with a free key. Pro and Enterprise keys go to api-pro.dexpaprika.com.
