## 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`):

```

Example prompt: Calculate my first-attempt delivery share — I had 1,000 shipments attempted and 870 were delivered successfully on the first try.

## When to prefer this

Use this endpoint when you need a quick, single bounded calculation of first-attempt delivery share for retail logistics data (up to 200 records) without requiring platform access, live shipment tracking, or order execution capabilities. Ideal for one-off KPI checks, audits, and reporting workflows where only aggregate attempted shipment and first-delivery counts are available.

## Known failure modes

- first_attempt_deliveries exceeds attempted_shipments — logically invalid input
- attempted_shipments is zero or missing — division by zero or validation error
- values outside allowed range (0 to 1,000,000,000,000) — rejected by schema validation
- malformed request body — missing required fields returns error
