Open one SSE connection and we push token prices and per-block pool reserve deltas as Base 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.

Base DEX data API — frequently asked questions
Which Base DEXes does the API cover?
18 Base DEXes including Uniswap V4, Aerodrome SlipStream 3, PancakeSwap V3, Curve, 13.84K pools in total, as of 2026-07-14 13:10 UTC.
How fresh is the Base data?
Data updates every Base block (~2s blocks). REST responses reflect the latest indexed block; SSE streams push changes as they happen, so there is no polling interval between your app and Base chain state.
Do I need an API key for Base data?
No. Every REST endpoint and SSE stream works without a key or signup: 200K requests per month free, per IP. A free API key (no credit card) raises that to 500K, and Pro ($99/mo) lifts the ceiling to 5M requests.
How do I get a Base token price with the API?
GET /networks/base/tokens/{address} returns the live USD price with 24h volume and liquidity in one call. For portfolios, /networks/base/multi/prices returns batched prices for up to 10 tokens per request.
Does streaming work for Base?
Yes. SSE streams at streaming.dexpaprika.com push Base token prices (/sse/prices) and per-block pool reserve deltas (/sse/reserves). That is a push-based reserves feed you will not find at CoinGecko or DexScreener.
What does the Base DEX API cost?
The free tier includes 200K requests per month per IP, with no API key or credit card, on every endpoint and every chain. A free registered key raises that to 500K/mo. Pro is $99/mo for 5M requests with priority support.
