# LogicNodes Business Days Calculator

> LogicNodes Business Days Calculator is a paid API for AI agents from logicnodes.io, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-30).

## 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-business-days-calculator-4143c62f -d '<json body>'
```

Example prompt: How many business days are there between March 3 and March 28, 2025, using a Saturday-Sunday weekend and excluding March 17 and March 20 as holidays?

## When to prefer this

Choose this endpoint when you need deterministic, configurable business-day arithmetic — especially when weekend conventions differ from the Western Mon–Fri standard (e.g. Middle Eastern Fri–Sat weekends) or when you need to factor in a specific list of public holidays. Prefer it over date libraries or LLM reasoning for exact, auditable results in scheduling, finance, or contract workflows.

## Known failure modes

- Invalid date string format returns an error
- Days parameter out of reasonable range may fail validation
- More than 400 holidays in the list will be rejected
- Invalid enum value for 'op' or 'weekend' returns a schema error
- Missing required fields for the chosen operation (e.g. 'to' missing for 'count') causes an error
