# Energy Readings Category Frequencies

> Energy Readings Category Frequencies 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).

Counts how often each category appears across energy reading records (meter, date, etc.) for up to 200 rows of consumption data.

## 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 energy-readings-category-frequencies-4f9d143d -d '<json body>'
```

Example prompt: Count how often each meter and date category appears across these energy readings — I have 4 records with meters group-a and group-b, dates from 2026-10-01 to 2026-10-04, and kWh values of 10, 20, 15, and 30.

## When to prefer this

Choose this endpoint when you need a fast, local frequency count of categorical values in energy reading data (e.g. how many records per meter or per date) without needing external enrichment, forecasting, or ranking. Ideal for data quality checks, coverage audits, and exploratory summaries of up to 200 energy records at a very low cost ($0.01 per call).

## Known failure modes

- Empty rows array returns validation error (minItems: 1)
- More than 200 rows submitted causes rejection (maxItems: 200)
- Missing required fields (row_id, meter, date, kwh, cost) causes schema validation failure
- Malformed date strings not matching YYYY-MM-DD pattern cause rejection
- row_id with zero length causes validation error (minLength: 1)

## How this service works

Energy readings - Category frequencies: Category frequencies for Energy readings. Up to 200 supplied typed records. Local numeric and data-quality processing; no external enrichment or forecasting. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded category frequencies deliverable.

## Output

A frequency table showing how often each distinct category value appears across the supplied energy reading records, covering fields such as meter ID and date. Returns bounded counts per unique category value with no external enrichment.
