# Batch Job Resources – Secondary-Measure Weighted Mean

> Batch Job Resources – 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 2026-10-19).

Computes a secondary-measure weighted mean over a batch of batch-job resource records (up to 200 rows), weighting one numeric field by another.

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 batch-job-resources-secondary-measure-weighted-mean-b32ba99d -d '<json body>'
```

Example prompt: I have 50 batch job records with job names, dates, duration_seconds, and peak_memory_mb — can you compute the duration_seconds weighted mean using peak_memory_mb as the secondary weight measure and give me a summary report?

## When to prefer this

Choose this endpoint when you have up to 200 batch job resource records and need a secondary-measure weighted mean — specifically when one numeric metric (e.g. memory) should weight the average of another (e.g. duration). Prefer it over generic statistics APIs when your data fits the batch-job domain schema (job name, date, duration_seconds, peak_memory_mb) and you want a low-cost ($0.01 USDC), self-contained local computation with no external data enrichment.

## Known failure modes

- Exceeding 200 rows returns a validation error
- Missing required fields (row_id, job, date, duration_seconds, peak_memory_mb) causes a schema rejection
- Invalid date format (non-YYYY-MM-DD) fails pattern validation
- Both numeric fields null for all rows may produce undefined/null result
- Payment failure via x402 returns 402 with no computation performed

## How this service works

Batch job resources - Secondary-measure weighted mean: Secondary-measure weighted mean for Batch job resources. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded secondary-measure weighted mean report.

## Output

A bounded descriptive analytics report containing the secondary-measure weighted mean of the chosen field (duration_seconds or peak_memory_mb), computed across all submitted batch job resource rows. No enrichment, forecasting, or external data is involved — purely local aggregation over the supplied records.
