# Coordinate Quality Checks — Numeric Row Ordering + Keyed Dataset Comparison

> Coordinate Quality Checks — Numeric Row Ordering + Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Performs numeric row ordering and keyed dataset comparison analytics on two supplied coordinate quality check datasets (checked_points, flagged_points) for up to 200 rows each.

## 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 coordinate-quality-checks-numeric-row-ordering-keyed-dataset-comparison-83a30393 -d '<json body>'
```

Example prompt: I have two batches of coordinate quality check records — a primary set and a comparison set, each with station_group, date, checked_points, and flagged_points — can you sort both by flagged_points and tell me where the two datasets differ by matching row_id?

## When to prefer this

Choose this endpoint when you have two batches of coordinate quality check records (with checked_points and flagged_points fields) that need to be (1) sorted/ranked numerically and (2) compared against each other by row key — all from supplied data with no external lookup. Ideal for auditing station group quality metrics across two time periods or datasets at very low cost ($0.01 for both reports).

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Missing required fields (row_id, station_group, date, checked_points, flagged_points) — validation error
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) — schema error
- Invalid date format (must match YYYY-MM-DD) — pattern validation failure
- Empty rows array (minItems: 1 not met) — schema error
- row_id longer than 80 characters — schema error

## How this service works

Coordinate quality checks — Numeric row ordering + Keyed dataset comparison: Numeric row ordering + Keyed dataset comparison for supplied coordinate quality checks records (checked_points, flagged_points). 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 independent analytical reports: (1) a numeric row ordering report ranking the supplied rows by the selected field (checked_points or flagged_points), and (2) a keyed dataset comparison report showing differences between the primary rows array and the other rows array matched by row_id. No external data is fetched; all analysis is performed on the supplied data.
