How this service works
Exact answers for AI agents: 40+ tools for EVM chains and Aptos, gas on 14 chains, never a guess. Free tier; pay per call in USDC (x402) on 13 networks.
Output
Returns a JSON object with ok: true, the tool name 'slippage_bounds', and the computed bound amount (minimum output or maximum input) based on the provided trade amount, direction, and slippage tolerance in basis points.
Example use cases
DEX swap slippage guard for bot
“My trading bot is about to execute a swap for 1000 USDC worth of ETH — calculate the minimum ETH output I should accept using 30 basis points slippage so I can set a safe min_out limit.”
Max input enforcement for fixed output
“I need exactly 200 DAI from a swap — what's the maximum amount of USDC I should allow as input if I'm okay with up to 100 basis points of slippage? Use direction max_in.”
Slippage check before DeFi transaction
“Before I approve this on-chain transaction, verify the slippage bounds for a trade amount of 750 tokens with a 25 basis point tolerance in the min_out direction so I know what the floor is.”
Technical details
Endpoint
POSThttps://logicnodes.io/paid/v1/tools/slippage_bounds?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs a precise, deterministic slippage bound calculation for a DeFi swap without guessing — ideal when building DeFi automation agents, swap bots, or pre-trade validation logic on EVM chains or Aptos. Prefer this over on-chain simulation when a fast, cheap, off-chain computation suffices and you pay per call in USDC via x402.
Side effects
- Invalid slippageBps outside 0–10000 range returns validation error
- Missing required fields (amount or direction) returns 400-style error
- Non-numeric or malformed amount string causes parse error
- Network or service unavailability returns 5xx error
