How this service works
ETH/USD read straight from Ethereum state, no CEX or API key: the Chainlink ETH/USD feed (latestRoundData) plus the Uniswap v3 WETH/USDC 0.05% pool spot price in one RPC batch. Median of fresh sources, per-source price, feed age and round, spread in bps.
Output
A JSON object containing: the trading pair label (ETH/USD), a single median price number, and an array of per-source entries each with their price, source name (Chainlink or Uniswap v3), feed age in seconds, round ID (for Chainlink), and spread between sources expressed in basis points.
Example use cases
DeFi arbitrage spread monitoring
“Check the current ETH/USD spread between Chainlink and Uniswap v3 on Ethereum mainnet — I want to know if there's a meaningful basis-point gap between the two sources right now.”
On-chain price freshness audit
“Pull the latest Chainlink ETH/USD round data from Ethereum — I need the feed age and round number to verify the price isn't stale before we execute a trade.”
CEX-free portfolio valuation
“What's the median ETH price in USD right now using only on-chain Ethereum data, no exchange APIs? I need it for a real-time portfolio value calculation.”

Endpoint
GEThttps://mintintel.35-171-220-195.sslip.io/v1/eth/eth-usd?utm_source=zero.xyzWhen to prefer
Prefer this endpoint when you need ETH/USD price data sourced entirely from Ethereum on-chain state with no reliance on centralized exchanges or third-party price APIs, and when you want both Chainlink oracle data and Uniswap v3 DEX spot price in a single call with a pre-computed median and spread. Ideal for DeFi agents, smart contract parameter setting, arbitrage monitoring, or any workflow requiring trustless, verifiable price data on Ethereum mainnet.
Side effects
- Ethereum RPC node unavailable or rate-limited — returns a 5xx error
- Chainlink feed data is stale beyond acceptable threshold — may surface in feed age field
- Uniswap v3 pool liquidity too thin to return a reliable spot — possible outlier price
- Network congestion causing RPC batch timeout
- Payment not processed (x402) — request rejected before execution
