Liquidity Book v2.2, v2.1 and v1 in one API
LFJ, the DEX formerly called Trader Joe, runs three generations on Avalanche: Liquidity Book v2.2 and v2.1, and the v1 AMM. The API keeps the old name in the dex_id: traderjoe_v2_2, traderjoe_v2_1 and traderjoe. Pool records carry dex_id. Swap rows carry factory_id, the contract the swap went through.

What the LFJ API returns
Pools
The pools the API indexes for LFJ, across every version on this page. A record carries both sides of the pair, current reserves, price in USD, and rolling volume and transaction counts.
Swaps
Individual transactions, newest first, with token symbols, USD prices at the time and the block they landed in. Reading them through the API needs a Dev plan or above.
Candles and streams
Historical OHLCV on any pool at the interval you ask for. Server-sent event streaming pushes swaps on a Dev plan or above, and prices run live on the Avalanche streaming page.
The data is the same shape on all 36 chains DexPaprika indexes. A query written against LFJ runs against any other venue once you change the network and the dex_name.

Questions
Do I need an API key to query LFJ data?
A free API key is the place to start. It needs no credit card and covers pools, tokens, DEXes and candles; swaps need a Dev plan or above. Register one at console.dexpaprika.com. Current quotas are on the pricing page.
Which LFJ version is a swap from?
Read factory_id on the transaction row: 0xb431…fe0c is LFJ Liquidity Book v2.2, 0x8e42…fd4e is LFJ Liquidity Book v2.1 and 0x9ad6…fa10 is LFJ v1. Pool records carry dex_id directly: traderjoe_v2_2 is LFJ Liquidity Book v2.2, traderjoe_v2_1 is LFJ Liquidity Book v2.1 and traderjoe is LFJ v1.
How do I list only LFJ pools on Avalanche?
Call /networks/avalanche/pools/search with dex_name=traderjoe_v2_2, then with dex_name=traderjoe_v2_1 and dex_name=traderjoe for the other versions. Add order_by=volume_usd_24h to get the busiest first.
How fresh is the LFJ 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 2026-10-15 21:57 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 LFJ swaps instead of polling?
Yes. /sse/transactions pushes swaps on a pool or token as they land, and it needs a Dev plan or above. The transactions streaming docs cover it, and a running price stream is on the Avalanche 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.
