How this service works
DeFi data for AI agents — yield rates, swap routes, IL calculator, liquidation risk, MEV scanner, TVL tracking. Powered by DeFiLlama + on-chain RPC data. Pay with USDC on Base via x402.
Output
Returns the impermanent loss percentage (impermanent_loss_pct), the mathematical formula used, an array of multiple price-change scenarios for comparison, and a plain-English interpretation of the loss magnitude and its implications for liquidity providers.
Example use cases
Pre-liquidity IL risk check
“I'm thinking about adding liquidity to a pool but ETH could move up 60% over the next month — how much impermanent loss would I suffer at that price change before I commit my funds?”
Post-pump LP loss assessment
“The token I'm LPing just pumped 120% since I entered the pool. Can you calculate how much impermanent loss I've actually experienced so far and explain the formula?”
Conservative downside scenario planning
“What would my impermanent loss look like if the asset price drops 40%? I want to understand whether the yield I'm earning is enough to offset that risk.”
Technical details
Endpoint
POSThttps://aracil.vercel.app/api/il-calculatorWhen to prefer
Choose this endpoint when you need a quick, on-demand computation of impermanent loss for a single price-change scenario with full formula transparency and scenario comparison, especially within an AI agent workflow that pays per-call via USDC on Base. Prefer it over manual calculations when you want interpreted natural-language output alongside the raw numbers.
Side effects
- Missing required price_change_pct field returns a validation error
- Extreme price change values (e.g. >10000%) may return unexpected or edge-case results
- Payment failure via x402 USDC on Base results in 402 response blocking the computation
- Non-numeric price_change_pct input returns a type error
