# Transport Ridership Data Quality Audit, Deduplication & Grouped Summary

> Transport Ridership Data Quality Audit, Deduplication & Grouped Summary 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).

Runs three analytical reports on transport ridership row data: a record quality audit, exact-row deduplication, and a grouped numeric summary of 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-data-quality-audit-deduplication-grouped-summary-06c1cbbe -d '<json body>'
```

Example prompt: I have up to 200 rows of bus ridership records with columns row_id, region, date, passenger_count, and service_count — can you run a quality audit, deduplicate exact rows, and give me a grouped numeric summary by region for passenger_count?

## When to prefer this

Choose this endpoint when you have up to 200 transport ridership records and need all three of: a data quality audit, deduplication of exact rows, and a grouped numeric summary — bundled at a single flat cost of $0.01 USDC. It is ideal for pre-processing pipeline steps before downstream analysis or reporting, especially when working offline without external data sources. Prefer alternatives if you need live transit data, predictions, or more than 200 rows.

## Known failure modes

- Payload exceeds 200 rows — request rejected with validation error
- Missing required fields (row_id, region, date, passenger_count, service_count) — schema validation failure
- Invalid date format (not YYYY-MM-DD) — pattern validation error
- Numeric values outside allowed range (-1T to +1T) — validation error
- Empty rows array — minItems constraint violated
- Payment not included or insufficient — x402 payment required error

## How this service works

Transport ridership — Record quality audit + Exact row deduplication + Grouped numeric summary: Record quality audit + Exact row deduplication + Grouped numeric summary for supplied transport ridership records (passenger_count, service_count). Up to 200 rows; 3 independent reports using shared local analytical engines. No live lookup, prediction, professional assessment or external action. 0.01 USDC includes 3 supplied-data reports for up to 200 rows.

## Output

Returns three independent reports: (1) a record quality audit flagging missing values, nulls, and anomalies per row; (2) an exact-row deduplication report identifying and removing duplicate records; and (3) a grouped numeric summary (totals, means, counts) of the selected field (passenger_count or service_count) broken down by region and/or date. All computed locally with no external lookups.
