# Material Libraries — Exact Row Deduplication + Secondary-Measure Weighted Mean

> Material Libraries — Exact Row Deduplication + 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).

Deduplicates exact rows and computes secondary-measure weighted means for material library records (material_count, texture_mb) across 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 material-libraries-exact-row-deduplication-secondary-measure-weighted-ec1b770d -d '<json body>'
```

Example prompt: Can you deduplicate these material library records and compute the texture_mb weighted mean? I have 4 rows: row-1 for group-a on 2026-10-01 with material_count 10 and texture_mb 1, row-2 for group-b on 2026-10-02 with material_count 20 and texture_mb 2, row-3 for group-a on 2026-10-03 with material_count 15 and texture_mb 3, and row-4 for group-b on 2026-10-04 with material_count 30 and texture_mb 4 — use texture_mb as the secondary field.

## When to prefer this

Choose this endpoint when you need both exact row deduplication and a secondary-measure weighted mean on material library records (material_count and texture_mb) in a single $0.01 call returning two reports. Best for game dev or creative pipelines that export asset group data with potential duplicates and need clean aggregates without live external data access.

## Known failure modes

- Exceeds 200-row limit — request rejected
- Missing required fields (row_id, asset_group, date, material_count, texture_mb) — validation error
- Invalid date format (not YYYY-MM-DD) — schema rejection
- Field enum value not one of material_count or texture_mb — error
- Empty rows array — minimum 1 item required

## How this service works

Material libraries — Exact row deduplication + Secondary-measure weighted mean: Exact row deduplication + Secondary-measure weighted mean for supplied material libraries records (material_count, texture_mb). 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) the deduplicated set of rows after exact-match removal, and (2) a weighted mean of the selected secondary measure (material_count or texture_mb) computed across the supplied records, all processed locally without external lookups.
