# Transport Ridership Record Quality Audit + Keyed Dataset Comparison

> Transport Ridership Record Quality Audit + 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).

Performs a record quality audit and keyed dataset comparison on up to 200 rows of transport ridership data (passenger_count, service_count), returning two independent 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 transport-ridership-record-quality-audit-keyed-dataset-comparison-6197e114 -d '<json body>'
```

Example prompt: Can you run a record quality audit and compare these two sets of ridership data? I have two datasets with up to 50 rows each — both have row_id, region, date, passenger_count, and service_count — and I want to see a quality report on the first set plus a side-by-side comparison of where the two datasets differ by key.

## When to prefer this

Choose this endpoint when you need both a data quality audit and a keyed comparison of two transport ridership datasets in a single call at low cost ($0.01 USDC for both reports). It is ideal for reconciliation workflows between two versions of the same dataset, pre-analysis data validation, or spotting discrepancies introduced during data updates. It does not perform live lookups, predictions, or external enrichment — prefer it for pure offline analytical reporting on supplied data up to 200 rows.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, region, date, passenger_count, service_count) causes schema rejection
- Malformed date strings not matching YYYY-MM-DD pattern are rejected
- row_id values exceeding 80 characters are rejected
- Numeric values outside the allowed range (-1,000,000,000,000 to 1,000,000,000,000) are rejected
- Empty rows array returns an error (minItems: 1)

## How this service works

Transport ridership — Record quality audit + Keyed dataset comparison: Record quality audit + 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

Two independent reports: (1) a record quality audit identifying issues such as nulls, out-of-range values, or malformed fields in the primary dataset; and (2) a keyed dataset comparison showing row-by-row and field-level differences between the primary and secondary datasets matched on row_id. Both reports are generated locally with no external lookups.
