Summary
Analyzes liquidity depth for Uniswap V3 pools by calculating price impact at 1%, 2%, 5%, and 10% levels. Built by Br0ski777 and hosted at orderbook-depth.api.klymax402.com, it connects via SSE transport to give you a read on how much slippage you'd face on different trade sizes. Useful when you're evaluating execution risk on DEX trades or building tools that need to estimate how deep a pool really is beyond the spot price. The x402 suffix suggests this is part of a broader toolkit, though the repo itself is sparse on implementation details. Reach for this when you need programmatic access to liquidity curves without scraping the chain yourself.
