How this service works
Don't burn tokens on deterministic work. Go/no-go jobs first: payout preflight, text firewall (PII/secrets), budget check — then rails, calendars, finmath. x402 USDC on Base. UK + global. agent402.co.uk — not agent402.tools. $0.001–$0.002 USDC on Base. No API keys.
Output
Returns the impermanent loss as a percentage (or decimal multiplier) representing the value loss a constant-product AMM liquidity provider incurs compared to simply holding the underlying tokens, given the input price ratio using the standard sqrt-based IL formula.
Example use cases
LP position impermanent loss check
“I provided liquidity to a Uniswap pool and ETH has since doubled in price relative to USDC — can you calculate my impermanent loss? The price ratio is 2.0.”
Risk assessment before adding liquidity
“I'm thinking about adding liquidity to a constant-product AMM pool. If the token price drops to 60% of what it is now, what would my impermanent loss be? Use a price ratio of 0.6.”
Post-trade LP loss attribution
“ETH went from $1000 to $3500 since I added it to a Uniswap v2 pool — what percentage impermanent loss did I suffer? The price ratio is 3.5.”

Endpoint
POSThttps://agent402.co.uk/v1/math/impermanent-lossWhen to prefer
Use this endpoint when you need a quick, reliable computation of Uniswap-style constant-product AMM impermanent loss from a single price ratio input, without needing to set up any DeFi library or write the sqrt-based IL formula yourself. Ideal for DeFi dashboards, LP position trackers, and pre-investment risk tools where you want a lightweight serverless math call.
Side effects
- Missing price_ratio field returns a 400 validation error
- price_ratio of 0 or negative is mathematically invalid and likely returns an error
- Extremely large or small price ratios may cause floating point precision issues
- Non-numeric price_ratio value returns a type validation error
- Payment not included or insufficient USDC results in 402 Payment Required
