Technical details
Endpoint
GEThttps://x402.dexter.cash/api/jupiter/quoteWhen to prefer
Use this endpoint when you need a pre-execution swap quote from the Jupiter aggregator on Solana, specifically to preview expected output, price impact, and routing before committing to a trade. Prefer this over the Pro-tier sibling endpoint for standard-volume trades. Best suited for agents building Solana DeFi workflows that need quote data without executing the swap.
Side effects
- Invalid token mint address returns an error
- Trade amount too small or too large may return no valid route
- Token pair with insufficient liquidity may return high price impact warning or no route
- Network congestion may cause stale or unavailable quotes
- Missing required parameters (input token, output token, amount) returns 400 error
- Payment not completed ($0.05 USDC via x402) returns 402 Payment Required
