# Public Project Delivery — Numeric Row Ordering + Adjacent Row Changes

> Public Project Delivery — Numeric Row Ordering + 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 2026-11-02).

Analyzes public project delivery records (planned_days, actual_days) by computing numeric row ordering and adjacent row changes across up to 200 rows, returning 2 analytical reports.

## 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 public-project-delivery-numeric-row-ordering-adjacent-row-changes-cf3baf1c -d '<json body>'
```

Example prompt: I have a batch of public project delivery records — can you run the numeric row ordering and adjacent row changes analysis on my planned_days data? Here are 4 rows: row-1 (2026-10-01, group-a, planned=10, actual=1), row-2 (2026-10-02, group-b, planned=20, actual=2), row-3 (2026-10-03, group-a, planned=15, actual=3), row-4 (2026-10-04, group-b, planned=30, actual=4).

## When to prefer this

Choose this endpoint when you need lightweight, local analytical computation on project delivery row data — specifically numeric ordering rankings and adjacent row-to-row delta calculations — without needing live data lookup, predictions, or external integrations. It is cost-effective at $0.01 for two reports on up to 200 rows.

## Known failure modes

- Fewer than 1 row submitted — minimum 1 row required
- More than 200 rows submitted — maximum is 200 rows
- Missing required fields (row_id, region, date, planned_days, actual_days) — validation error
- Invalid date format (must be YYYY-MM-DD) — pattern mismatch error
- row_id exceeds 80 characters or is empty — validation error
- Payment not attached or insufficient — x402 payment required (0.01 USDC)

## How this service works

Public project delivery — Numeric row ordering + Adjacent row changes: Numeric row ordering + Adjacent row changes for supplied public project delivery records (planned_days, actual_days). 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

Two analytical reports: (1) a numeric row ordering of the specified field (planned_days or actual_days) across all submitted rows, and (2) adjacent row changes showing the difference between consecutive row values, derived entirely from the supplied data with no external lookups.
