# Crop Yield Records – Adjacent Row Changes

> Crop Yield Records – Adjacent Row Changes is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Computes adjacent row-to-row changes for a supplied batch of crop yield records, returning local descriptive analytics on hectares or harvest_kg.

## 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-adjacent-row-changes-262ee063 -d '<json body>'
```

Example prompt: I have four crop yield records — group-a on 2026-10-01 with 10 hectares and 1 kg harvest, group-b on 2026-10-02 with 20 hectares and 2 kg, group-a on 2026-10-03 with 15 hectares and 3 kg, and group-b on 2026-10-04 with 30 hectares and 4 kg — can you calculate the adjacent row-to-row changes in hectares across all of them?

## When to prefer this

Choose this endpoint when you have a sequential list of crop yield records (up to 200 rows) and need a quick, local adjacent row-to-row change computation on hectares or harvest_kg — no forecasting, no external enrichment. Ideal for lightweight descriptive analytics within an agent workflow where cost must stay minimal ($0.01 per call) and results must be fast and deterministic.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maximum batch size
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Unknown field value outside ['hectares','harvest_kg'] enum — rejected
- Missing required fields (row_id, crop, date) — validation error
- Payment not completed via x402 — endpoint returns 402 Payment Required

## How this service works
