How this service works
Simulates a guarded swap execution to preview outcomes before sending a real trade.
Output
Returns a simulated swap execution result including estimated output token amount, fee breakdown, slippage impact, risk flags from the guarded execution layer, and a preview of whether the trade would succeed — without sending any real transaction.
Example use cases
Example prompt
“Before I actually execute it, can you dry-run a swap of 100 USDC to ETH on Base and show me the estimated output, fees, and any risk flags so I know what to expect?”
Technical details
Endpoint
POSThttps://x402.fiasignals.com/acp-direct/guarded-swap-execute-dry-runWhen to prefer
Use this endpoint when an AI agent needs to preview the outcome of a guarded swap before committing real funds — especially useful for risk-averse trading workflows, user confirmation flows, or when validating that swap parameters will yield acceptable results. Prefer this over a live execution endpoint when the goal is estimation, validation, or user approval without on-chain side effects.
Side effects
- Invalid token pair returns an error indicating unsupported or unrecognized tokens
- Insufficient liquidity for the requested swap amount results in a simulation failure
- Malformed swap parameters cause a 400-level validation error
- Smart contract risk check flags the token as unsafe, blocking simulation
- Network or RPC issues may cause a 500-level server error
- Missing required fields such as amount or token addresses return a parameter error
