How this service works
TrustDex is a non-custodial Solana DEX. Best-route swaps through Jupiter, EVM trading across 7 chains, native bridging, and live token risk grades. No KYC, no accounts, no custody.
Output
Returns a JSON object with ok status, plan metadata, an estimate flag, the expected buyAmount in the token's base units, minBuyAmount accounting for slippage, and nativeUsd price if available.
Example use cases
Pre-trade slippage check on Base
“Before I execute my trade, can you check how much WETH I'd get for selling 500 USDC on Base chain (chain ID 8453)? The USDC address is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 and I want native ETH back.”
Arbitrage opportunity scan across chains
“Can you get me a price quote for swapping 10000 USDC to DAI on Arbitrum (chain ID 42161)? Sell token is 0xFF970A61A04b1cA14834A43f5dE4533eBDDB5CC8, buy token is 0xDA10009cBd5D07dd0CeCc66161FC93D7c9000da1.”
DeFi bot pre-execution pricing
“I'm about to execute a swap — first get me an estimate of how much MATIC I'd receive for selling 2000 of native token on Polygon (chain ID 137) so I can sanity-check the output before submitting the transaction.”
Technical details
Endpoint
GEThttps://trustdex.app/api/v1/x402/swap/evm/priceWhen to prefer
Use this endpoint when you need a fast, no-KYC, non-custodial EVM token swap price estimate across any of TrustDex's 7 supported EVM chains without setting up an account. Prefer it over centralized exchange price APIs when privacy matters or when operating on chains like Base, Arbitrum, or Polygon with a need for best-route aggregation.
Side effects
- Invalid or unsupported chainId returns an error or empty result
- Unrecognized token address (non-0x format or unlisted token) causes a failed lookup
- sellAmount of zero or non-integer string may return a validation error
- Unsupported chain returns no route
- Network congestion may cause stale or unavailable price data
- Payment of 0.002 USDC not fulfilled triggers 402 response blocking the call
