# Simulation Caches — Category Frequencies + Secondary-Measure Weighted Mean

> Simulation Caches — Category Frequencies + 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 2026-10-21).

Computes category frequency counts and a secondary-measure weighted mean for simulation cache records (cache_gb, simulation_seconds) grouped by asset group, for up to 200 rows.

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 simulation-caches-category-frequencies-secondary-measure-weighted-mean-5fb95f16 -d '<json body>'
```

Example prompt: Analyze my simulation cache records by asset group — I have 4 rows with dates from 2026-10-01 to 2026-10-04, asset groups 'group-a' and 'group-b', cache sizes of 10, 20, 15, and 30 GB, and simulation times of 1, 2, 3, 4 seconds. Give me the category frequencies and the weighted mean for cache_gb.

## When to prefer this

Choose this endpoint when you have structured simulation cache records with asset group labels and need both frequency-based categorical analysis and a weighted mean of a numeric metric in a single call, without needing live data, predictions, or external enrichment. Ideal for batch summarization of up to 200 simulation records at very low cost ($0.01).

## Known failure modes

- Missing required fields (row_id, asset_group, date, cache_gb, simulation_seconds) causes validation error
- Exceeding 200 rows returns an error or truncation
- Invalid date format (not YYYY-MM-DD) fails pattern validation
- Null values in the numeric fields may affect weighted mean calculation
- Invalid field enum value (not cache_gb or simulation_seconds) causes request rejection

## How this service works

Simulation caches — Category frequencies + Secondary-measure weighted mean: Category frequencies + Secondary-measure weighted mean for supplied simulation caches records (cache_gb, simulation_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) category frequencies showing how often each asset_group value appears across the submitted rows, and (2) a weighted mean of the selected numeric field (cache_gb or simulation_seconds) weighted by the secondary measure — both computed locally without external lookups, for up to 200 input rows.
