# Camera Coverage Grouped Numeric Summary and Equal-Width Histogram

> Camera Coverage Grouped Numeric Summary and 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 grouped numeric summary and an equal-width histogram for camera coverage records (shot_count or coverage_seconds) across up to 200 rows, producing 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-grouped-numeric-summary-and-equal-width-histogram-161386d5 -d '<json body>'
```

Example prompt: I have camera coverage records for two asset groups — group-a and group-b — over several dates, with shot_count and coverage_seconds. Can you give me a grouped numeric summary and a 10-bin equal-width histogram for shot_count across up to 200 rows?

## When to prefer this

Choose this endpoint when you have up to 200 camera coverage records and need both a grouped statistical summary by asset group and a histogram of the distribution in a single $0.01 call. It is ideal for offline/batch analytical passes on supplied data — no live data lookup, external prediction, or third-party integration is involved. Prefer it over general-purpose statistics APIs when your data specifically involves shot_count and coverage_seconds fields tied to asset groups and dates.

## Known failure modes

- More than 200 rows supplied — exceeds the maximum row limit
- Missing required fields (row_id, asset_group, date, shot_count, or coverage_seconds) in any row
- date field not matching YYYY-MM-DD pattern
- bins value outside the 1–30 range
- All values for the selected field are null — insufficient data for computation
- Malformed JSON body causing request rejection

## How this service works

Camera coverage — Grouped numeric summary + Equal-width histogram: Grouped numeric summary + 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 analytical reports: (1) a grouped numeric summary breaking down the chosen field (shot_count or coverage_seconds) by asset_group, including statistics such as count, mean, min, max, and standard deviation; and (2) an equal-width histogram with the specified number of bins showing the frequency distribution of the chosen field across all supplied rows.
