Get swap transactions for a DEX pool with the DexPaprika API

GET /networks/{network}/pools/{pool_address}/transactions returns the swaps in one pool, newest first: who swapped, how much of each token moved, and both tokens’ prices in USD at that moment. It needs a Dev, Pro or Enterprise key on api-pro.dexpaprika.com, sent as the whole Authorization header:

curl -s -H "Authorization: $DEXPAPRIKA_API_KEY" \
  "https://api-pro.dexpaprika.com/networks/ethereum/pools/0x88e6a0c2ddd26feeb64f039a2c41296fcb3f5640/transactions?limit=1"

That swap put 0.00018 WETH into the USDC/WETH pool on Uniswap V3 and took 0.45 USDC out.

Which plan you need

Caller	What you get
No key or free key	`403` with `plan_required`
Dev, Pro, Enterprise	Every swap, on `api-pro.dexpaprika.com`

Without a paid key the same call answers:

Compare plans on pricing and manage your key in console.dexpaprika.com. On the free tier, pool details gives you the totals these swaps add up to: buys, sells, swap count and USD volume over 5m, 15m, 30m, 1h, 6h and 24h, with no key.

Reading a swap

Field	Meaning
`id`, `log_index`	Transaction hash and the position of the swap event in its block. One transaction can hold several swaps, so the pair identifies a swap
`sender`, `recipient`	Wallets or contracts on each side of the swap
`token_0`, `token_1` and their `_symbol`	The pool’s two tokens
`amount_0`, `amount_1`	Signed raw amounts, from the pool’s side: positive went into the pool, negative came out
`volume_0`, `volume_1`	The same amounts without the sign, in whole tokens
`price_0`, `price_1`	Each token’s price in units of the other
`price_0_usd`, `price_1_usd`	Each token’s USD price at the time of the swap
`created_at`, `created_at_block_number`	When the swap happened

Which way did it go? The token with a negative amount left the pool, so that is what the trader bought. In the example amount_1 is negative: the trader sold WETH for USDC. The buys and sells that pool details reports count swaps the same way, from the pool’s base token: a buy takes the base token out of the pool. What was it worth? volume_0 * price_0_usd, or the same for token 1.

Parameters

Parameter	What it does
`limit`	Swaps per response, 1 to 100, default 10
`page`	Page number from 1 to 100
`cursor`	Continue from a swap: pass `next_cursor` from the previous response
`from`, `to`	Only swaps at or after `from` and at or before `to`: `-1h`, Unix seconds, RFC3339 or a date

page stops at 100: page=101 answers 400. To read further back, switch to cursor. A response to a cursor request carries next_cursor instead of page_info, and following it keeps going past where page stops.

The last hour of swaps in Python

This script reads every swap in the last hour, classifies each as a buy or a sell of the pool’s base token, and lists the largest. One request for the pool, then one per 100 swaps:

import os
import requests

# A Dev, Pro or Enterprise key. Free keys and keyless calls get 403.
API = os.environ.get("DEXPAPRIKA_API", "https://api-pro.dexpaprika.com")
HEADERS = {"Authorization": os.environ["DEXPAPRIKA_API_KEY"]}

network = "ethereum"
pool_address = "0x88e6a0c2ddd26feeb64f039a2c41296fcb3f5640"  # USDC/WETH, Uniswap V3


def get(path, **params):
    r = requests.get(f"{API}{path}", headers=HEADERS, params=params, timeout=30)
    r.raise_for_status()
    return r.json()


pool = get(f"/networks/{network}/pools/{pool_address}")
base = pool["base_token_id"]

swaps, page = [], 1
while True:
    data = get(f"/networks/{network}/pools/{pool_address}/transactions",
               **{"from": "-1h", "limit": 100, "page": page})
    swaps += data["transactions"]
    if page >= data["page_info"]["total_pages"]:
        break
    page += 1


def side(tx):
    base_amount = tx["amount_0"] if tx["token_0"] == base else tx["amount_1"]
    return "buy" if base_amount < 0 else "sell"


def usd(tx):
    return tx["volume_0"] * tx["price_0_usd"]


buys = [tx for tx in swaps if side(tx) == "buy"]
print(f"{len(swaps)} swaps in the last hour: {len(buys)} buys, {len(swaps) - len(buys)} sells")
print(f"buy volume ${sum(map(usd, buys)):,.0f}, total ${sum(map(usd, swaps)):,.0f}\n")
for tx in sorted(swaps, key=usd, reverse=True)[:3]:
    print(f"{tx['created_at']}  {side(tx):<4}  ${usd(tx):>12,.0f}  {tx['sender']}")

327 swaps in the last hour: 190 buys, 137 sells
buy volume $1,469,755, total $2,685,555

2026-10-12T14:38:35Z  buy   $      89,251  0x854abc33363a71781186d80c32ee092ce6a757ab
2026-10-12T14:23:59Z  buy   $      74,105  0xbdb3ba9ffe392549e1f8658dd2630c141fdf47b6
2026-10-12T14:38:23Z  buy   $      66,535  0x51c72848c68a965f66fa7a88855f9f7784502a7f

Output from 12 October 2026, on a Pro key. The counts match the 1h window of pool details for the same pool, give or take the swaps that landed between the two calls: pool details read 189 buys and 134 sells a minute earlier.

Things to know

Use next_cursor, not the last id. A cursor includes the swap it names. Passing the id of the last swap you already have returns that swap again as the first row; next_cursor points at the next one. Raw amounts overflow JavaScript numbers. amount_0 and amount_1 are integers in the token’s smallest unit, and an 18-decimal token easily passes 2^53. JSON.parse rounds them silently. Use volume_0 and volume_1, or a JSON parser that keeps big integers. total_pages can be larger than you can reach. It counts every matching swap, while page stops at 100. Bound the range with from and to, or walk it with cursor. Each response costs one credit, whatever the limit, so ask for 100 at a time. See credit usage. For a live feed, stream instead of polling. The transactions stream pushes each swap as it happens, on the same plans.
