Your first Polygon call

▸ No API key. No signup. Paste and run.

# top Polygon pools by 24h volume
curl "https://api.dexpaprika.com/networks/polygon/pools/search?order_by=volume_usd_24h&sort=desc&limit=5"

# live price for WPOL
curl "https://api.dexpaprika.com/networks/polygon/tokens/0x0d500b1d8e8ef31e21c99d1db9a6444d3adf1270"

// top Polygon pools by 24h volume. No key, no signup
const res = await fetch(
    'https://api.dexpaprika.com/networks/polygon/pools/search?order_by=volume_usd_24h&sort=desc&limit=5'
)
const { results } = await res.json()
for (const pool of results) {
    console.log(pool.dex_name, Math.round(pool.volume_usd_24h))
}

# top Polygon pools by 24h volume. No key, no signup
import requests

pools = requests.get(
    "https://api.dexpaprika.com/networks/polygon/pools/search",
    params={"order_by": "volume_usd_24h", "sort": "desc", "limit": 5},
).json()["results"]

for pool in pools:
    print(pool["dex_name"], round(pool["volume_usd_24h"]))

Streaming: stop polling Polygon

Open one SSE connection and we push token prices and per-block pool reserve deltas as Polygon 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 WPOL price ticks on Polygon. One connection, no polling
curl -N "https://streaming.dexpaprika.com/sse/prices?chain=polygon&address=0x0d500b1d8e8ef31e21c99d1db9a6444d3adf1270&method=token_price"

# push: per-block reserve deltas for WPOL pools
curl -N "https://streaming.dexpaprika.com/sse/reserves?chain=polygon&address=0x0d500b1d8e8ef31e21c99d1db9a6444d3adf1270&method=token_reserves"

# push: live swaps touching WPOL, as they land on Polygon
curl -N "https://streaming.dexpaprika.com/sse/transactions?chain=polygon&address=0x0d500b1d8e8ef31e21c99d1db9a6444d3adf1270&method=token"
