## 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`):

## When to prefer this

Choose this endpoint when you need a lightweight, no-signup, pay-per-call API to derive the calendar quarter from any ISO-8601 date or timestamp, especially in agentic workflows that process arbitrary dates at runtime without wanting to implement date-math logic locally.

## Known failure modes

- Invalid or malformed date string returns an error — date must conform to ISO-8601 format
- Missing date field results in a bad request response
- Dates outside supported range may return unexpected results
- Network or payment failure (USDC/x402) prevents the call from completing

## How this service works
