## 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 parking-utilization-daily-sum-series-56871883 -d '<json body>'
```

Example prompt: Summarize my parking lot data into a daily sum series for occupied_spaces — I have records for zones A and B from October 1–4, 2026, with values like 10, 20, 15, and 30 occupied spaces per day.

## When to prefer this

Choose this endpoint when you have raw daily parking utilization records (occupied and available space counts per zone) and need a simple, bounded daily sum aggregation with no forecasting or enrichment. It is ideal for local descriptive analytics on a small-to-medium dataset (up to 200 rows) where you want a per-day total for a single numeric metric across zones, delivered at minimal cost ($0.01 USDC).

## Known failure modes

- Missing required fields (row_id, zone, date, occupied_spaces, available_spaces) cause validation errors
- Date strings not matching YYYY-MM-DD pattern are rejected
- Exceeding 200 rows in the input array returns a payload-too-large error
- Null numeric values may be excluded from aggregation silently
- Invalid field enum value (anything other than occupied_spaces or available_spaces) causes a bad-request error
- Payment of 0.01 USDC not attached or rejected causes a 402 Payment Required response
