How this service works
Best swap quote for a token pair on an EVM chain, compared across two public DEX aggregators (KyberSwap and Velora/ParaSwap): amount out, USD values, estimated gas in USD, price impact against the input's USD value and the pools/DEXes used, plus which aggregator gives more. Chains: Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche. Indicative quotes, not executable orders.
Output
Returns a ranked list of swap quotes from multiple DEX aggregators, each with: aggregator name, output token amount, USD value in/out, gas cost in USD, price impact percentage, and route taken. Also includes the overall best aggregator, token addresses, decimals, spread percent, and the timestamp the quotes were checked.
Example use cases
Best swap rate before trading
“I want to swap 2.5 ETH for USDC on Arbitrum — can you check which DEX aggregator gives me the best output amount and what the price impact and gas cost will be?”
Cross-aggregator price comparison
“Compare the quotes for swapping 500 USDC to WETH on Base across all available aggregators — I want to know the best route, estimated output, and which aggregator wins.”
DeFi yield strategy token acquisition
“I need to buy 1000 USDC worth of the WBTC token on Polygon — what's the best aggregator to use, what route would it take, and how much gas would it cost me?”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/crypto/1inch-pathfinder-quotes?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to compare real-time swap quotes across multiple DEX aggregators simultaneously without signing up for individual APIs. It is ideal for pre-trade analysis, finding the best execution price, estimating gas costs, and checking price impact across Ethereum, Base, Arbitrum, Optimism, Polygon, BSC, and Avalanche — all in a single pay-per-call request with no API key required.
Side effects
- Unsupported chain name returns error or empty quotes
- Invalid or unrecognized token contract address returns no quotes
- Amount of zero or negative returns validation error
- Network congestion or aggregator API downtime may return partial quotes
- Token pair with no liquidity returns empty quotes array
