# Source Attribution Analytics — Exact Row Deduplication + Trailing Mean Series

> Source Attribution Analytics — 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 2026-10-24).

Deduplicates source attribution records by exact row match and computes a trailing mean time series over cited_sources or verified_links metrics for 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 source-attribution-analytics-exact-row-deduplication-trailing-mean-cd4e3486 -d '<json body>'
```

Example prompt: Can you deduplicate my source attribution records and compute a trailing mean series with a window of 3 for cited_sources? I have rows with fields row_id, channel_group, date, cited_sources, and verified_links — up to 50 rows across groups like 'news-a' and 'news-b'.

## When to prefer this

Choose this endpoint when you have up to 200 source attribution records (with cited_sources and/or verified_links metrics) and need both an exact duplicate row removal pass and a rolling/trailing mean time series in a single low-cost call. It is ideal for news, media, or content analytics pipelines that need lightweight data quality and trend analysis on supplied data without any external API calls or predictions.

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — exceeds maximum, request rejected
- Invalid date format (not YYYY-MM-DD) — schema validation error
- Window size less than 2 or greater than 200 — validation error
- Missing required fields (row_id, channel_group, date, cited_sources, verified_links) — schema validation error
- cited_sources or verified_links values outside allowed numeric range — validation error

## How this service works

Source attribution — Exact row deduplication + Trailing mean series: Exact row deduplication + Trailing mean series for supplied source attribution records (cited_sources, verified_links). 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 records from the supplied source attribution rows, and (2) a trailing mean time series computed over the selected field (cited_sources or verified_links) with the specified rolling window, both derived entirely from the supplied data with no external lookups.
