# Data Collection Completeness — Exact Row Deduplication + Trailing Mean Series

> Data Collection Completeness — Exact Row Deduplication + Trailing Mean Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-25).

Performs exact row deduplication and trailing mean series computation on up to 200 data collection completeness records containing observed and expected values, returning two analytical reports.

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 data-collection-completeness-exact-row-deduplication-trailing-mean-35bdc4e4 -d '<json body>'
```

Example prompt: I have 150 rows of data collection completeness records with observed and expected values per course group and date — can you deduplicate exact duplicate rows and compute a trailing mean series over observed_values with a window of 7?

## When to prefer this

Choose this endpoint when you need exactly two local analytical operations — exact row deduplication and a trailing moving average — applied to a dataset of up to 200 data collection completeness records (observed vs expected values) in a single low-cost call. Ideal for education analytics pipelines where data quality (deduplication) and trend smoothing (rolling mean) are both required without external lookups or predictions.

## Known failure modes

- Input array exceeds 200 rows — request rejected
- Window size larger than number of input rows — trailing mean series may be incomplete or return nulls
- Missing required fields (row_id, date, observed_values, expected_values) — validation error
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- All rows are duplicates — deduplication report returns empty or single-row result
- Null numeric values in selected field — trailing mean may skip or propagate nulls

## How this service works

Data collection completeness — Exact row deduplication + Trailing mean series: Exact row deduplication + Trailing mean series for supplied data collection completeness records (observed_values, expected_values). 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) an exact row deduplication report identifying and removing fully duplicate rows from the input dataset, and (2) a trailing mean series computed over the selected numeric field (observed_values or expected_values) using the specified rolling window size, both derived locally from the supplied rows without any external data lookup.
