▸ 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

Streaming: stop polling Polygon

Open one SSE connection and we push token prices and per-block pool reserve deltas as Polygon state changes — the only push-based reserves feed on the market. Poll loops re-fetch unchanged state and still miss mid-block moves; push delivery makes the gap between on-chain state and your app the network round-trip, nothing else.

# 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"

Polygon DEX data API — frequently asked questions

Which Polygon DEXes does the API cover?

10 Polygon DEXes including Uniswap V4, QuickSwap V2, Uniswap V3 — 3,168 pools in total, as of 2026-07-10 20:56 UTC.

How fresh is the Polygon data?

Data updates every Polygon block (~2s blocks). REST responses reflect the latest indexed block; SSE streams push changes as they happen — there is no polling interval between your app and Polygon chain state.

Do I need an API key for Polygon data?

No. Every REST endpoint and SSE stream works without a key or signup — 200K requests per month free. Pro ($99/mo) lifts the ceiling to 5M requests.

How do I get a Polygon token price with the API?

GET /networks/polygon/tokens/{address} returns the live USD price with 24h volume and liquidity in one call. For portfolios, /networks/polygon/multi/prices returns batched prices for up to 10 tokens per request.

Does streaming work for Polygon?

Yes — SSE streams at streaming.dexpaprika.com push Polygon token prices (/sse/prices) and per-block pool reserve deltas (/sse/reserves). It is the only push-based reserves feed on the market.

What does the Polygon DEX API cost?

The free tier includes 200K requests per month with no API key or credit card, on every endpoint and every chain. Pro is $99/mo for 5M requests with priority support.
