How this service works
Read on-chain state of a Uniswap V3 pool: token0/token1 addresses + decimals, fee tier, current sqrtPriceX96, tick, in-range liquidity, and the decoded human-readable spot price (token1 per token0). One $0.002 call replaces ~6 RPC roundtrips on the caller's side.
Output
Returns token0 and token1 contract addresses with their decimals, the pool's fee tier, the raw sqrtPriceX96 value, current tick, in-range liquidity amount, and a decoded human-readable spot price expressed as token1 per token0 — all in a single response replacing approximately 6 separate RPC calls.
Example use cases
Example prompt
“What's the current spot price, fee tier, and in-range liquidity for the Uniswap V3 pool at 0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640 on Ethereum?”
Technical details
Endpoint
POSThttps://agent402.tools/api/dex-poolWhen to prefer
Use this endpoint when you need a compact, affordable snapshot of a Uniswap V3 pool's current on-chain state without setting up your own RPC infrastructure or making multiple round-trips. It is ideal for agents that need a decoded human-readable spot price alongside raw pool parameters (sqrtPriceX96, tick, liquidity) in one call across Ethereum, Base, Polygon, Arbitrum, or Optimism.
Side effects
- Invalid or non-existent pool address returns an error
- Unsupported network name returns a validation error
- Pool address is not a Uniswap V3 pool contract — call may fail or return garbage data
- Network RPC unavailable or congested — timeout or transient error
- Malformed 0x address format causes immediate rejection
