How this service works
Impermanent loss % and hold-vs-LP value for a 50/50 pool from the price ratio (new/old) of the volatile asset; nets optional fees earned to show true LP outcome.
Output
Returns the impermanent loss as a percentage, the comparative value of a hold-only strategy versus the LP position, and the net LP outcome after any optional fees earned are factored in — showing whether the LP position outperformed or underperformed simply holding the assets.
Example use cases
Post-exit LP position review
“I just withdrew from a 50/50 WBTC/USDC pool. The price of WBTC went from $30,000 when I entered to $45,000 now, and I earned about $200 in fees on a $10,000 initial position. How much impermanent loss did I suffer, and did the fees make up for it?”
Pre-entry LP risk assessment
“I'm thinking about entering a 50/50 SOL/USDC pool. If SOL's price were to go up 2.5x or drop to 40% of its current value, what would my impermanent loss percentage be in each scenario? I want to understand the downside before I commit.”
AMM pool strategy comparison
“I'm comparing two strategies: holding my tokens versus LP-ing in a 50/50 pool. The volatile asset's price has changed from my entry by a ratio of 1.8. Can you compute the impermanent loss and show me the hold value versus LP value so I can decide which performed better?”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/impermanent-loss-calculatorWhen to prefer
Choose this endpoint when you need a fast, on-demand computation of impermanent loss for a standard 50/50 constant-product AMM pool (Uniswap v2 style). It is ideal for DeFi agents evaluating LP profitability, post-exit analysis, or pre-entry risk modeling. Prefer this over building the IL formula manually when you also want the hold-vs-LP comparison and optional fee netting in a single call.
Side effects
- Invalid or zero price ratio returns a validation error
- Negative fees or nonsensical inputs rejected with 4xx error
- Price ratio of 1 (no price change) returns 0% IL as expected edge case
- Missing required price ratio field causes a 400 Bad Request
- Service downtime returns 5xx error
