# Join Coverage Analytics: Numeric Interval Filter + Trailing Mean Series

> Join Coverage Analytics: Numeric Interval Filter + 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 2026-10-19).

Runs two analytical reports on join coverage data (matched_rows, source_rows): filters records by a numeric interval and computes a trailing mean time series, for 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 join-coverage-analytics-numeric-interval-filter-trailing-mean-series-ff0ab310 -d '<json body>'
```

Example prompt: Analyze my join coverage data — filter matched_rows between 0 and 100, then compute a trailing mean with a window of 3, across these rows: row-1 on 2026-10-01 group-a with source_rows=10 matched_rows=50, row-2 on 2026-10-02 group-b with source_rows=8 matched_rows=80, row-3 on 2026-10-03 group-a with source_rows=12 matched_rows=40.

## When to prefer this

Choose this endpoint when you have pre-collected join coverage data (matched_rows, source_rows) and need two specific local analytical transformations — numeric interval filtering and trailing mean computation — without any external data lookup, prediction, or ML model. Ideal for data quality pipelines auditing join completeness metrics in batches of up to 200 rows at minimal cost ($0.01 USDC for both reports).

## Known failure modes

- Fewer than 1 row supplied — request rejected
- More than 200 rows supplied — request rejected
- Invalid date format (not YYYY-MM-DD) — validation error
- Window size outside [2, 200] — validation error
- Minimum or maximum outside allowed numeric range — validation error
- Missing required row fields (row_id, dataset_group, date, matched_rows, source_rows) — validation error
- Payment not provided or insufficient USDC — 402 payment required

## How this service works

Join coverage — Numeric interval filter + Trailing mean series: Numeric interval filter + Trailing mean series for supplied join coverage records (matched_rows, source_rows). 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) rows from the input dataset whose selected field (matched_rows or source_rows) falls within the specified numeric interval [minimum, maximum], and (2) a trailing mean time series for the selected field computed over the specified window size, both derived from the supplied join coverage records.
