## 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 first-attempt-delivery-share-target-gap-calculation-a7498431 -d '<json body>'
```

Example prompt: We attempted 1,200 shipments last month and 1,044 were successfully delivered on the first attempt — our target is 90%. Can you calculate the gap between our actual first-attempt delivery share and that target?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.01 USDC) computation of first-attempt delivery share versus a target for retail logistics use cases, without needing live rate feeds, platform access, or order execution. Ideal for offline batch KPI reporting on up to 200 shipment records.

## Known failure modes

- Validation error if attempted_shipments is zero or negative (exclusiveMinimum: 0)
- Error if first_attempt_deliveries exceeds attempted_shipments in a logically inconsistent way
- Request rejected if more than 200 records are supplied
- Missing required fields (attempted_shipments or first_attempt_deliveries) cause a schema validation error
- Network or payment failure results in no report returned
