# LogicNodes Slippage Bounds Calculator

> LogicNodes Slippage Bounds Calculator is a paid API for AI agents from logicnodes.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-28).

Computes the minimum output or maximum input token amount for a DeFi swap given a trade amount and slippage tolerance in basis points

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability logicnodes-slippage-bounds-calculator-2948ea5e -d '<json body>'
```

Example prompt: I'm about to swap 500 USDC on a DEX — can you calculate the minimum tokens I should accept as output using a slippage tolerance of 50 basis points?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
