# Camera Coverage Trailing Mean Series + Equal-Width Histogram

> Camera Coverage Trailing Mean Series + Equal-Width Histogram is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-17).

Computes a trailing mean time series and an equal-width histogram over camera coverage records (shot_count or coverage_seconds) for up to 200 rows, 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 camera-coverage-trailing-mean-series-equal-width-histogram-ad91b392 -d '<json body>'
```

Example prompt: I have 4 camera coverage records with shot_count and coverage_seconds — can you run both a trailing mean series (window of 2) and a 5-bin equal-width histogram on the shot_count field for those rows?

## When to prefer this

Choose this endpoint when you have camera coverage tabular data (shot counts and/or coverage seconds) and need both a smoothed time trend (trailing mean) and a distributional overview (histogram) in a single low-cost call. It is ideal for offline/batch analytical passes on up to 200 rows without needing a live data connection, external prediction, or professional assessment. It is not suitable for real-time streaming analytics, large datasets exceeding 200 rows, or use cases requiring correlation, outlier detection, or deduplication (other sibling endpoints cover those).

## Known failure modes

- Fewer than 1 row supplied — minimum 1 row required
- More than 200 rows submitted — exceeds maximum row limit
- Window size larger than number of rows — trailing mean cannot be computed
- Invalid date format — must match YYYY-MM-DD pattern
- Missing required row fields (row_id, date, shot_count, coverage_seconds) — schema validation error
- Bins value outside 1–30 range — rejected by schema
- Field value not one of 'shot_count' or 'coverage_seconds' — enum validation error
- Payment not completed — x402 payment required before response is returned

## How this service works

Camera coverage — Trailing mean series + Equal-width histogram: Trailing mean series + Equal-width histogram 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 reports: (1) a trailing mean series showing the rolling average of the selected field (shot_count or coverage_seconds) over the specified window across sorted records, and (2) an equal-width histogram showing the frequency distribution of the selected field divided into the specified number of bins, including bin boundaries and counts.
