## 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 crop-yield-records-daily-sum-series-9b877ac2 -d '<json body>'
```

Example prompt: Take these crop records — wheat on 2026-10-01 with 10 hectares and 1 kg harvest, corn on 2026-10-02 with 20 hectares and 2 kg harvest — and give me a daily sum series for harvest_kg.

## When to prefer this

Choose this endpoint when you have raw, per-row crop yield records and need a simple daily sum aggregation of hectares or harvest_kg without any external enrichment, forecasting, or complex statistics. It is ideal for local descriptive analytics on small-to-medium datasets (up to 200 rows) at very low cost ($0.01 USDC). Prefer alternatives if you need outlier detection (use the IQR outlier flags profile), weighted means, or forecasting beyond the supplied data.

## Known failure modes

- Fewer than 1 row supplied returns an error (minItems: 1)
- More than 200 rows submitted exceeds the maxItems limit and will be rejected
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Missing required fields (row_id, crop, date, hectares, harvest_kg) cause record rejection
- Invalid field enum value (not 'hectares' or 'harvest_kg') causes a bad request error
- Payment not included or insufficient USDC triggers 402 payment required
