How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

Output

Returns the computed impermanent loss for the specified liquidity position, including IL percentage, dollar value lost relative to a hold strategy, current token composition, and position value metrics.

Example use cases

LP checking Uniswap V3 IL

“Can you tell me how much impermanent loss I've accumulated on my Uniswap V3 position with token ID 845321 on Ethereum? My wallet address is 0xAbC123456def.”

Curve pool IL monitoring on Arbitrum

“I'm providing liquidity on a Curve pool at address 0xPool456... on Arbitrum — can you calculate my impermanent loss for my wallet 0xMyWallet789?”

Balancer LP position IL assessment

“How much impermanent loss am I taking on my Balancer liquidity position on Ethereum? Pool address is 0xBalancerPool321 and my wallet is 0xMyAddress654.”

Pool address does not match wallet's position returns empty or error
Payment of 0.005 USDC via x402 fails, request is rejected with 402 status
Network RPC errors or on-chain data unavailability cause timeouts
