# Accessibility Observations — Duplicate Key Report + Numeric Row Ordering

> Accessibility Observations — Duplicate Key Report + 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).

Analyzes up to 200 rows of accessibility observation data (checked_elements, flagged_elements) to produce a duplicate key report and numeric row ordering, delivered as 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 accessibility-observations-duplicate-key-report-numeric-row-ordering-a7d4d825 -d '<json body>'
```

Example prompt: Can you run a duplicate key report and numeric row ordering on my accessibility scan data? I have rows for site groups 'group-a' and 'group-b' from 2026-10-01 through 2026-10-04, with checked_elements and flagged_elements counts, and I want to analyze the flagged_elements field.

## When to prefer this

Choose this endpoint when you need fast, self-contained analytical reports on supplied accessibility observation records — specifically duplicate key detection and numeric ordering — without requiring external data lookups, live web scraping, or AI-generated assessments. Ideal for data quality checks on accessibility audit pipelines handling up to 200 rows at a time.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected
- Missing required fields (row_id, site_group, date, checked_elements, flagged_elements) on any row causes validation failure
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- row_id values that are empty strings fail minLength validation
- field enum value not one of checked_elements or flagged_elements causes rejection

## How this service works

Accessibility observations — Duplicate key report + Numeric row ordering: Duplicate key report + Numeric row ordering for supplied accessibility observations records (checked_elements, flagged_elements). 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: (1) a duplicate key report identifying which row_id values appear more than once in the supplied dataset, and (2) a numeric row ordering ranking all rows by the selected field (checked_elements or flagged_elements). Covers up to 200 input rows with no external lookups or live data.
