# LogicNodes Money Calculator

> LogicNodes Money 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).

Performs precise monetary arithmetic (rounding, addition, subtraction, multiplication, splitting, ratio-based splitting) on currency amounts using exact decimal math

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-money-calculator-5b7a296b -d '<json body>'
```

Example prompt: Split $347.89 equally among 4 people and round each share down to the nearest cent.

## When to prefer this

Choose this endpoint when you need exact, deterministic monetary arithmetic — especially for splitting bills, fee calculations, or financial distributions where floating-point precision errors from native language runtimes would be unacceptable. Ideal for AI agents operating in DeFi or payment contexts where a rounding error can cause fund loss. Prefer this over doing arithmetic locally when you need banker's rounding, proportional splitting by ratios, or reproducible exact results across environments.

## Known failure modes

- Invalid or missing 'op' enum value returns an error
- Non-numeric 'amount' or 'other' strings cause parse failure
- 'parts' of 0 or negative values cause division errors for split operations
- Ratios that don't sum to a meaningful total may cause unexpected proportional results
- Missing required fields for the chosen operation (e.g. no 'factor' for multiply) return validation errors
- Network or payment (x402) issues cause 402 or timeout responses

## 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

A JSON object with ok: true, the tool name 'money_calc', and the computed result — a precisely calculated monetary value (or array of values for splits) free of floating-point errors, in the requested currency with the specified rounding applied.
