# Road Segment Observations — Record Quality Audit & Numeric Row Ordering

> Road Segment Observations — Record Quality Audit & Numeric Row Ordering 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).

Audits record quality and orders rows numerically for road segment observation data (length_m, travel_seconds) across up to 200 rows, returning 2 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 road-segment-observations-record-quality-audit-numeric-row-ordering-20afc17e -d '<json body>'
```

Example prompt: Can you audit the quality of these road segment records and then order the rows numerically by length_m? I have 4 rows with row IDs row-1 through row-4, station groups group-a and group-b, dates from 2026-10-01 to 2026-10-04, and length/travel-seconds values filled in — I need both reports.

## When to prefer this

Choose this endpoint when you have road segment observation records with length_m and travel_seconds fields and need both a data quality audit and numeric row ordering in a single low-cost call. It is purpose-built for road/transport domain data up to 200 rows and returns two coordinated reports for $0.01 USDC. Prefer alternatives if you need live traffic data, route planning, prediction, or datasets larger than 200 rows.

## Known failure modes

- More than 200 rows submitted — request rejected or truncated
- Missing required fields (row_id, date, length_m, travel_seconds) — validation error
- Invalid date format (not YYYY-MM-DD) — schema rejection
- Invalid field enum value (not length_m or travel_seconds) — error response
- Empty rows array — schema minimum violation
- Payment not included or insufficient — 402 Payment Required

## How this service works

Road segment observations — Record quality audit + Numeric row ordering: Record quality audit + Numeric row ordering for supplied road segment observations records (length_m, travel_seconds). 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 independent analytical reports for the supplied road segment rows: (1) a record quality audit identifying issues such as nulls, out-of-range values, and malformed entries across the dataset; and (2) a numeric row ordering report ranking rows by the specified field (length_m or travel_seconds). Both reports are generated locally with no external lookups.
