# Product Photography Completion Analytics — Histogram & Correlation

> Product Photography Completion Analytics — Histogram & Correlation 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).

Runs an equal-width histogram on a chosen measure and a two-measure Pearson/rank correlation between required_images and completed_images for up to 200 product photography records.

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 product-photography-completion-analytics-histogram-correlation-b273b158 -d '<json body>'
```

Example prompt: Can you run a histogram with 10 bins on required_images and also compute the correlation between required_images and completed_images for these 50 product photography records across our store groups?

## When to prefer this

Choose this endpoint when you have up to 200 product photography records with required_images and completed_images fields and need both a distributional view (histogram) and a linear association measure (correlation) in a single paid call. Ideal for retail or e-commerce teams auditing photo production progress across store groups. Not suitable for real-time monitoring, predictive modeling, or datasets exceeding 200 rows.

## Known failure modes

- Exceeds 200-row limit — request rejected or truncated
- Invalid date format (must be YYYY-MM-DD) causes row validation failure
- Null values in required_images or completed_images may reduce effective correlation sample size
- bins parameter outside 1–30 range rejected
- Missing required fields (row_id) causes schema validation error
- Fewer than 2 non-null paired rows results in undefined correlation

## How this service works

Product photography — Equal-width histogram + Two-measure correlation: Equal-width histogram + Two-measure correlation for supplied product photography records (required_images, completed_images). 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 statistical reports: (1) an equal-width histogram over the selected field (required_images or completed_images) with configurable bin count (1–30) showing bin edges and frequencies, and (2) a two-measure correlation report quantifying the statistical relationship between required_images and completed_images across the submitted rows. No external data is fetched; all computation is performed locally on the supplied rows.
