Streaming: stop polling Arc

Open one SSE connection and we push token prices and per-block pool reserve deltas as Arc 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 USDC price ticks on Arc. One connection, no polling
curl -N "https://streaming.dexpaprika.com/sse/prices?chain=arc&address=0x3600000000000000000000000000000000000000&method=token_price"

# push: per-block reserve deltas for USDC pools
curl -N "https://streaming.dexpaprika.com/sse/reserves?chain=arc&address=0x3600000000000000000000000000000000000000&method=token_reserves"

# push: live swaps touching USDC, as they land on Arc
curl -N "https://streaming.dexpaprika.com/sse/transactions?chain=arc&address=0x3600000000000000000000000000000000000000&method=token"

Arc DEX data API — frequently asked questions

Which Arc DEXes does the API cover?

3 Arc DEXes including Uniswap V4, 8,199 pools in total, as of 2026-09-16 13:58 UTC.

How fresh is the Arc data?

Data updates every Arc block. REST responses reflect the latest indexed block; SSE streams push changes as they happen, so there is no polling interval between your app and Arc chain state.

Do I need an API key for Arc data?

For anything past a first test, yes. A free API key takes under a minute, needs no credit card, and covers 100K requests per month on every endpoint and every chain. Dev ($30/mo) raises that to 500K, and Pro ($99/mo) lifts the ceiling to 5M requests.

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

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

Does streaming work for Arc?

Yes. SSE streams at streaming.dexpaprika.com push Arc 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 Arc DEX API cost?

The free tier includes 100K requests per month with a free API key, no credit card, on every endpoint and every chain. Dev is $30/mo for 500K requests, and Pro is $99/mo for 5M requests with priority support.
