How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a `fee_fraction_needed` field (a decimal number, e.g. 0.0202) representing the fraction of pool value that must be earned in trading fees for a liquidity provider to break even against impermanent loss at the given price ratio. Also includes a schema identifier string.
Example use cases
LP position evaluation before entry
“I'm thinking of providing liquidity to a pool where the token price might double. What fee fraction do I need to earn to break even against impermanent loss if the price ratio goes to 2.0?”
Post-price-move LP profitability check
“The asset in my LP position dropped to 80% of its original price, so the price ratio is now 0.8. How much in fees do I need to have collected to have broken even against the impermanent loss?”
Sensitivity analysis for volatile token pair
“Can you run an IL fee breakeven calculation for a price ratio of 3.0? I want to understand how high the fee fraction needs to be before it even makes sense to LP a volatile pair like this.”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/il-fee-breakeven?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, precise, on-demand computation of the impermanent loss breakeven fee fraction for a given price ratio — particularly in DeFi agent workflows evaluating LP positions, AMM strategies, or yield farming profitability. It is pay-per-result with no signup, making it ideal for agents that need occasional one-off IL math without integrating a full financial analytics platform.
Side effects
- Missing or invalid price_ratio (non-numeric or absent) may return a 400 or error response
- Price ratio of exactly 1.0 (no price change) may return 0 or near-zero fee fraction — trivially correct but may confuse callers
- Negative or zero price ratios are mathematically undefined and likely cause errors
- Payment failure via x402 protocol will block the computation from executing
