# URL Canonicalization — Duplicate Key Report + Trailing Mean Series

> URL Canonicalization — Duplicate Key Report + 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 2026-10-22).

Analyzes supplied URL canonicalization records to produce a duplicate key report and a trailing mean series for observed or unique URL counts, up to 200 rows.

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 url-canonicalization-duplicate-key-report-trailing-mean-series-062fd65e -d '<json body>'
```

Example prompt: Can you run a duplicate key report and trailing mean series on my URL canonicalization data? I have rows for site_group 'group-a' and 'group-b' with observed_urls values from 2026-10-01 to 2026-10-04, and I want the trailing mean over a window of 3 periods for the observed_urls field.

## When to prefer this

Choose this endpoint when you need to simultaneously audit URL canonicalization records for duplicate key combinations AND compute a rolling/trailing mean time series on URL count metrics, all in a single low-cost call. It is ideal for offline/batch analysis of supplied data (no live lookups), supporting up to 200 rows. Prefer this over general-purpose analytics when your data specifically contains site_group, date, observed_urls, and unique_urls fields and you need both data quality (deduplication) and trend (rolling mean) outputs together.

## Known failure modes

- Input array exceeds 200 rows — request will be rejected
- Missing required fields (row_id, site_group, date, observed_urls, unique_urls) cause validation errors
- Invalid date format (not YYYY-MM-DD) triggers schema rejection
- Window parameter outside 2–200 range causes an error
- Field value not in enum ['observed_urls','unique_urls'] causes rejection
- Null numeric values may affect trailing mean computation quality

## How this service works

URL canonicalization — Duplicate key report + Trailing mean series: Duplicate key report + Trailing mean series for supplied url canonicalization records (observed_urls, unique_urls). 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 rows with repeated key combinations across the supplied URL canonicalization records, and (2) a trailing mean series computed over the specified window for the chosen field (observed_urls or unique_urls), covering up to 200 rows of input data.
