How this service works
27 paid endpoints for trading bots
Output
Returns the estimated price impact as a percentage, effective execution price after impact, slippage estimate, and relevant liquidity pool depth metrics for the specified token pair and trade size on the target DEX
Example use cases
Pre-trade slippage check for bot
“Before my trading bot executes a swap of 200 ETH for USDC on Uniswap v3 on Ethereum, check the price impact so I know if slippage will be acceptable — I want to abort if impact is over 0.5%.”
Whale trade impact assessment
“I'm about to buy 2 million dollars worth of ARB token on Arbitrum using a DEX aggregator — can you estimate the price impact and tell me how much the market price will move against me?”
Liquidity depth comparison
“Compare the price impact of swapping 10,000 USDC for MATIC on Polygon across different pool sizes — I want to know how deep the liquidity is before I route my order.”
Technical details
Endpoint
POSThttps://x402-chain-intel.vercel.app/api/dex/price-impactWhen to prefer
Use this endpoint when you need pre-trade price impact analysis for DEX swaps before committing a transaction on-chain — especially for larger trades where slippage could be significant. Prefer this over generic price feeds when you need simulation of actual pool mechanics rather than just spot prices.
Side effects
- Token pair not found or no liquidity pool exists for the specified DEX
- Chain ID not supported
- Trade size exceeds available liquidity causing unreliable estimate
- Invalid token contract addresses
- Rate limit or payment failure returning 402
- Stale on-chain data if block is not recent
