# Land Parcel Observations — Exact Row Deduplication + Duplicate Key Report

> Land Parcel Observations — Exact Row Deduplication + Duplicate Key Report is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Deduplicates land parcel observation records and generates a duplicate key report for up to 200 rows of area and perimeter data.

## 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 land-parcel-observations-exact-row-deduplication-duplicate-key-report-2937e807 -d '<json body>'
```

Example prompt: I have a batch of up to 200 land parcel observation records with area_m2 and perimeter_m measurements — can you deduplicate the exact rows and give me a duplicate key report showing which row_ids appeared more than once?

## When to prefer this

Choose this endpoint when you have land parcel observation records (with area_m2 and perimeter_m measurements) and need both exact row deduplication and a duplicate key report in a single call. It is ideal for data cleaning pipelines before geospatial analysis, auditing merged survey exports, or validating parcel datasets up to 200 rows. Prefer this over general-purpose deduplication tools when your data specifically includes the land parcel schema (station_group, date, area_m2, perimeter_m).

## Known failure modes

- More than 200 rows submitted — exceeds maximum batch size limit
- Missing required fields (row_id, station_group, date, area_m2, or perimeter_m) cause validation errors
- Invalid date format (must match YYYY-MM-DD pattern)
- Empty rows array returns an error — minItems is 1
- Numeric values outside the allowed range (-1,000,000,000,000 to 1,000,000,000,000) are rejected
- Payment failure for the $0.01 USDC fee blocks processing

## How this service works

Land parcel observations — Exact row deduplication + Duplicate key report: Exact row deduplication + Duplicate key report for supplied land parcel observations records (area_m2, perimeter_m). Up to 200 rows; 2 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 2 supplied-data reports for up to 200 rows.

## Output

Returns two reports: (1) an exact row deduplication result identifying and removing fully identical rows from the input dataset, and (2) a duplicate key report listing which row_id or key combinations appear more than once across the supplied land parcel observations (area_m2, perimeter_m fields). Both reports are generated locally from the supplied data with no external lookups.
