## 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-base-100-rebase-report-f5000992 -d '<json body>'
```

Example prompt: I have 4 months of shipment data — month 1 had 100 attempted shipments and 87 delivered on first try, month 2 had 110 attempted with 95.7 delivered — can you rebase the first-attempt delivery share to 100 starting from month 1?

## When to prefer this

Choose this endpoint when you have raw first-attempt delivery counts and shipment volumes across multiple periods and need a normalized, base-100 indexed series for trend analysis or reporting. Ideal for retail logistics analysts who want to compare delivery performance over time without being distracted by absolute volume differences. Not suitable for live rate lookups, order management, platform integrations, or delivery ETA predictions.

## Known failure modes

- Fewer than 2 rows provided — minimum 2 rows required
- More than 200 rows submitted — maxItems limit exceeded
- attempted_shipments value of zero — violates exclusiveMinimum constraint
- base_index out of range — must be between 0 and 199 and within actual row count
- Missing required fields attempted_shipments or first_attempt_deliveries in any row
- Payment not included or rejected — $0.01 USDC required per call via x402 protocol
