How this service works
Request an indicative read-only swap quote.
Output
Returns a JSON object with a data field containing the indicative swap quote details (estimated output, route, venue used), plus meta information including cache hit status, cache age in milliseconds, latency, data sources consulted, any failed sources, and a partial flag indicating if the result is incomplete. Also includes a success boolean and ISO timestamp.
Example use cases
Pre-trade price check on Solana
“Before I swap, can you get me a quote for exchanging 1000 USDC for SOL on Solana via Jupiter with a max slippage of 100 bps? Just show me the estimate, don't execute anything.”
Cross-venue rate comparison on Ethereum
“I want to compare swap rates for converting 2 WETH to USDC on Ethereum — can you pull quotes from both Jupiter and 0x venues so I can see which gives the better price?”
Arbitrage opportunity sizing on Arbitrum
“What's the estimated output if I swap 10,000 USDT to ARB on Arbitrum using 0x, with slippage capped at 75 basis points? I want to size a potential arb before committing funds.”
Technical details
Endpoint
POSThttps://mcp.dropenginehq.com/api/estimate-trade-execution?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, indicative swap price across Solana, Ethereum, Base, Arbitrum, Optimism, or Polygon without committing to a trade. It is ideal for pre-trade analysis, price comparison between Jupiter and 0x, slippage estimation, and portfolio rebalancing previews. Prefer this over on-chain simulations when you need low-latency quotes with aggregator routing intelligence but zero execution risk.
Side effects
- Unsupported chain/venue combination returns error or partial result
- Token address not recognized by the specified venue results in failed_sources entry
- Amount exceeds maximum (1,000,000,000,000) or is zero/negative — rejected by schema validation
- max_slippage_bps outside 1-500 range causes validation failure
- Venue (Jupiter or 0x) temporarily unavailable populates failed_sources and may return partial:true
- Rate limit or payment failure ($0.01 USDC x402) causes 402 or 429 response
