# Transport Ridership Duplicate Key Report & Numeric Interval Filter

> Transport Ridership Duplicate Key Report & Numeric Interval Filter is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Runs two local analytical reports on supplied transport ridership data: identifies duplicate row keys and filters rows by a numeric interval on passenger or service counts.

## 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-duplicate-key-report-numeric-interval-filter-b24617eb -d '<json body>'
```

Example prompt: Can you check my transport ridership records for duplicate row IDs and also filter them to only show rows where passenger_count is between 50 and 500? Here are the rows: row-1 (2026-10-01, group-a, passenger_count=10, service_count=1), row-2 (2026-10-02, group-b, passenger_count=200, service_count=2), row-1 (2026-10-03, group-a, passenger_count=450, service_count=3).

## When to prefer this

Choose this endpoint when you need lightweight, offline data quality checks on transport ridership datasets — specifically duplicate key detection and numeric range filtering — without requiring a live database, external lookup, or ML model. Ideal for pre-ingestion validation pipelines, batch data audits, or quick ad-hoc QA on transit data exports of up to 200 rows.

## Known failure modes

- Empty rows array returns validation error
- More than 200 rows submitted causes rejection
- Invalid date format (not YYYY-MM-DD) causes schema validation failure
- Minimum greater than maximum may return empty interval filter results
- Missing required fields (row_id, region, date) causes item-level rejection
- Non-numeric values in passenger_count or service_count when not null cause type errors

## How this service works

Transport ridership — Duplicate key report + Numeric interval filter: Duplicate key report + Numeric interval filter 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 duplicate key report listing any row_ids that appear more than once in the supplied data, and (2) a numeric interval filter report listing all rows where the selected field (passenger_count or service_count) falls within the specified minimum and maximum bounds. Up to 200 rows processed per call.
