# Color Swatches Exact Row Deduplication and Secondary-Measure Weighted Mean

> Color Swatches Exact Row Deduplication and 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 2026-10-25).

Deduplicates exact rows and computes a secondary-measure weighted mean for color swatch records (luminance, chroma) — delivering two analytical reports from supplied data.

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 color-swatches-exact-row-deduplication-and-secondary-measure-weighted-bfc8492f -d '<json body>'
```

Example prompt: I have a dataset of color swatch records with luminance and chroma values — can you deduplicate exact duplicate rows and compute the chroma-weighted mean of luminance across up to 200 rows, and give me both reports?

## When to prefer this

Choose this endpoint when you have up to 200 color swatch records with luminance and chroma measurements and need both exact row deduplication and a secondary-measure weighted mean in a single call. It is ideal for creative asset pipelines, design system audits, or color data quality checks where no live lookup or external data is needed — just local computation on supplied rows at minimal cost ($0.01 USDC for two reports).

## Known failure modes

- Input rows exceed 200 item limit — request will be rejected
- Missing required fields (row_id, asset_group, date, luminance, chroma) cause validation errors
- Invalid date format (must be YYYY-MM-DD) triggers schema error
- Numeric values outside ±1,000,000,000,000 range are rejected
- Empty rows array (minItems:1 not satisfied) returns error
- All rows are duplicates — deduplication report may return single or zero rows

## How this service works

Color swatches — Exact row deduplication + Secondary-measure weighted mean: Exact row deduplication + Secondary-measure weighted mean for supplied color swatches records (luminance, chroma). 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 on the supplied color swatch data: (1) a deduplicated set of rows after removing exact duplicates, and (2) a secondary-measure weighted mean for the selected field (luminance or chroma), computed locally without any external lookup or live data.
