# Transport Ridership — Exact Row Deduplication + Duplicate Key Report

> Transport Ridership — Exact Row Deduplication + Duplicate Key Report 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).

Deduplicates exact rows and generates a duplicate key report for transport ridership records (passenger_count, service_count) across up to 200 rows.

## 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-exact-row-deduplication-duplicate-key-report-88b5f0f1 -d '<json body>'
```

Example prompt: I have a batch of up to 200 transport ridership records with passenger_count and service_count fields — can you run exact row deduplication and generate a duplicate key report so I can see which rows are identical and which row_ids are repeated?

## When to prefer this

Choose this endpoint when you need both exact row deduplication and a duplicate key report in a single call for transport ridership data (passenger_count, service_count). It is ideal for data quality pipelines, pre-load audits, or post-merge cleanups where the dataset is up to 200 rows and no live external data or predictions are required. Prefer it over generic deduplication tools when your data specifically contains ridership fields and you want two structured analytical reports from one cheap ($0.01 USDC) call.

## Known failure modes

- Exceeding 200 rows in the input array returns a validation error
- Missing required fields (row_id, region, date, passenger_count, service_count) cause row-level rejection
- Invalid date format (not YYYY-MM-DD) triggers a pattern validation error
- Numeric values outside the allowed range (-1,000,000,000,000 to 1,000,000,000,000) are rejected
- Empty rows array (minItems: 1 not met) returns an error
- Payment of 0.01 USDC not settled via x402 protocol results in an authorization failure

## How this service works

Transport ridership — Exact row deduplication + Duplicate key report: Exact row deduplication + Duplicate key report 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 reports: (1) an exact row deduplication report identifying which rows are identical across all fields, and (2) a duplicate key report listing row_ids that appear more than once — both derived analytically from the supplied ridership records without any external lookups.
