# Transport Ridership Date-by-Category Pivot + Keyed Dataset Comparison

> Transport Ridership Date-by-Category Pivot + 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 2026-10-26).

Analyzes up to 200 transport ridership records by producing a date-by-category pivot table and a keyed comparison between two supplied datasets for passenger_count or service_count.

## 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 transport-ridership-date-by-category-pivot-keyed-dataset-comparison-a897fedf -d '<json body>'
```

Example prompt: I have two sets of transit ridership records (up to 200 rows each) with region, date, passenger_count, and service_count — can you pivot the first dataset by date and region for passenger_count, and also compare it row-by-row against the second dataset?

## When to prefer this

Choose this endpoint when you have structured transport ridership data (passenger_count, service_count) already in hand and need both a date-by-region pivot analysis and a comparison between two versions of the dataset in a single paid call. It is best for offline/batch analytical workflows where you supply all data locally and need no live data fetching, predictions, or external enrichment.

## Known failure modes

- More than 200 rows submitted — exceeds maximum row limit
- Missing required fields (row_id, region, date, passenger_count, or service_count) — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema rejection
- Numeric values outside allowed range (-1,000,000,000,000 to 1,000,000,000,000) — validation failure
- Empty rows array — minimum 1 item required
- Invalid field enum value (must be 'passenger_count' or 'service_count') — schema rejection

## How this service works

Transport ridership — Date by category pivot + Keyed dataset comparison: Date by category pivot + Keyed dataset comparison for supplied transport ridership records (passenger_count, service_count). 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 analytical reports: (1) a date-by-category pivot table cross-tabulating the selected field (passenger_count or service_count) across dates and regions, and (2) a keyed row-by-row comparison between the primary and secondary supplied datasets highlighting differences — all computed locally with no external data lookups.
