## 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 fleet-fuel-records-category-frequencies-af955c0a -d '<json body>'
```

Example prompt: Can you count how many fuel records we have per vehicle group from this fleet fuel log? I have 4 records: row-1 for group-a on 2026-10-01 with 10 km and 1 litre, row-2 for group-b on 2026-10-02 with 20 km and 2 litres, row-3 for group-a on 2026-10-03 with 15 km and 3 litres, and row-4 for group-b on 2026-10-04 with 30 km and 4 litres.

## When to prefer this

Choose this endpoint when you have up to 200 fleet fuel records and need a quick, local descriptive frequency count of categorical fields (vehicle groups, dates) with no need for external data enrichment, forecasting, or statistical inference beyond counts.

## Known failure modes

- Empty rows array — minimum 1 item required
- More than 200 rows submitted — exceeds maxItems limit
- Missing required fields (row_id, vehicle, date, distance_km, fuel_litres) on any record
- Invalid date format — must match YYYY-MM-DD pattern
- row_id exceeds 80-character maxLength
- Payment failure — insufficient USDC balance for $0.01 per call
