How this service works
Simulate a swap on a public DEX quote API and report price impact, fees and expected output. DO NOT execute the swap. Returns a go/no-go recommendation.
Output
Returns a structured JSON response including: estimated output token amount, price impact percentage, protocol and network fees, and an explicit go/no-go recommendation based on the simulated quote — without submitting any on-chain transaction.
Example use cases
Pre-trade slippage check on Uniswap
“I want to swap 5000 USDC for WBTC on Uniswap — can you simulate that first and tell me the price impact and expected WBTC output, and whether it's a good idea to proceed?”
Fee estimation before large DeFi trade
“Before I swap 50 ETH for USDC on a DEX, simulate the trade for me and break down the fees and expected output so I can decide if it's worth doing right now.”
Comparing swap viability across amounts
“Simulate swapping 100 ARB for USDC on Aerodrome and tell me the price impact and whether you'd recommend executing the swap at this size.”
Technical details
Endpoint
POSThttps://defi-intel-agent-gateway.gg-neo15.workers.dev/v1/dex/pre-swap-simulationWhen to prefer
Use this endpoint when you need a safe, read-only pre-trade analysis before committing to a DEX swap — especially for large trades where price impact and fees materially affect profitability. Prefer this over live execution endpoints when the goal is to evaluate feasibility, compare trade sizes, or surface a human-readable go/no-go recommendation without any on-chain risk. Best used immediately before a potential swap decision, not for historical analysis or portfolio-wide batch simulations.
Side effects
- DEX API unavailable or rate-limited — returns error with no quote data
- Unsupported token pair — returns error indicating pair not found on specified DEX
- Insufficient liquidity for the requested swap size — returns high price impact warning or no-go recommendation
- Invalid or malformed swap parameters — returns validation error
- Network congestion causing stale quote data — may return outdated price impact figures
