# Camera Coverage Analytics — Adjacent Row Changes + Secondary-Measure Weighted Mean

> Camera Coverage Analytics — Adjacent Row Changes + Secondary-Measure Weighted Mean is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-31).

Computes adjacent row-to-row changes and secondary-measure weighted mean across up to 200 camera coverage records (shot_count, coverage_seconds) in two independent local 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 camera-coverage-analytics-adjacent-row-changes-secondary-measure-e3b239cc -d '<json body>'
```

Example prompt: I have a dataset of up to 200 camera coverage records with shot counts and coverage seconds across different asset groups and dates — can you run the adjacent row changes report and the secondary-measure weighted mean report on them, using shot_count as the primary field?

## When to prefer this

Choose this endpoint when you have tabular camera coverage data (shot_count and coverage_seconds) with up to 200 rows and need both sequential row-delta analysis and a weighted mean summary in a single low-cost call ($0.01 USDC for both reports). Ideal for media production analytics, footage auditing, or asset group comparisons where no external data or predictions are needed — purely local computation on supplied data.

## Known failure modes

- More than 200 rows submitted — exceeds maxItems limit, request rejected
- Missing required fields (row_id, asset_group, date, shot_count, coverage_seconds) — validation error
- Invalid date format not matching YYYY-MM-DD pattern — schema validation failure
- Non-numeric values in shot_count or coverage_seconds — type error
- Empty rows array (minItems: 1 not met) — request rejected
- Invalid field enum value (must be shot_count or coverage_seconds) — validation error

## How this service works

Camera coverage — Adjacent row changes + Secondary-measure weighted mean: Adjacent row changes + Secondary-measure weighted mean for supplied camera coverage records (shot_count, coverage_seconds). 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) adjacent row changes showing sequential delta values for the selected field (shot_count or coverage_seconds) across up to 200 input rows, and (2) a secondary-measure weighted mean summarizing the weighted average using the complementary metric. Both reports are computed locally with no external lookups.
