# Metadata Completeness — Duplicate Key Report + Base-100 Series

> Metadata Completeness — Duplicate Key Report + Base-100 Series 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 metadata completeness records to produce a duplicate key report and a base-100 index series for up to 200 rows of present_fields/expected_fields data.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 metadata-completeness-duplicate-key-report-base-100-series-d4fdf2a3 -d '<json body>'
```

Example prompt: I have up to 200 rows of metadata completeness records with site_group, date, present_fields, and expected_fields — can you run a duplicate key report and generate a base-100 index series starting at row index 0 for the present_fields column?

## When to prefer this

Choose this endpoint when you need two complementary offline analytical reports — duplicate key detection and base-100 normalization — on metadata completeness data in a single low-cost call. It is ideal for data quality audits of metadata pipelines where you want to identify repeated keys and index field coverage ratios without any external API calls or predictions.

## Known failure modes

- Missing required fields (row_id, site_group, date, present_fields, expected_fields) cause validation errors
- More than 200 rows submitted — exceeds maximum and will be rejected
- Invalid date format (must match YYYY-MM-DD pattern) causes schema validation failure
- base_index out of range (must be 0–199) returns an error
- Null numeric values for present_fields or expected_fields may produce incomplete index calculations

## How this service works

Metadata completeness — Duplicate key report + Base-100 series: Duplicate key report + Base-100 series for supplied metadata completeness records (present_fields, expected_fields). 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) a duplicate key report identifying rows with repeated key combinations (row_id, site_group, date), and (2) a base-100 index series for the selected field (present_fields or expected_fields) anchored to the specified base_index row, computed locally without any external lookups.
