# Energy Readings Numeric Row Ordering

> Energy Readings Numeric Row Ordering 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).

Sorts up to 200 energy reading records by a numeric field (kWh or cost) and returns them in ordered sequence.

## 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-numeric-row-ordering-53779b03 -d '<json body>'
```

Example prompt: Sort these energy meter readings by kWh — I have 4 rows: row-1 for meter group-a on 2026-10-01 with 10 kWh costing $1, row-2 for group-b on 2026-10-02 with 20 kWh costing $2, row-3 for group-a on 2026-10-03 with 15 kWh costing $3, and row-4 for group-b on 2026-10-04 with 30 kWh costing $4.

## When to prefer this

Choose this endpoint when you need a fast, cheap ($0.01 USDC) local numeric sort of energy meter records (up to 200 rows) by kWh or cost with no external API calls, forecasting, or enrichment. Ideal for pre-processing energy data before visualization or analysis pipelines where simple ordering by a numeric field is the only transformation needed.

## Known failure modes

- Missing required fields (row_id, meter, date, kwh, cost) on any row causes validation error
- Date field not matching YYYY-MM-DD pattern causes rejection
- More than 200 rows submitted exceeds maxItems limit
- Invalid field enum value (not 'kwh' or 'cost') causes error
- Empty rows array (minItems: 1 not met) returns error
- Payment not included or insufficient USDC causes 402 response

## How this service works

Energy readings - Numeric row ordering: Numeric row ordering 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 numeric row ordering deliverable.

## Output

Returns the submitted energy reading rows reordered numerically by the specified field (kwh or cost). Each row retains its original fields (row_id, meter, date, kwh, cost) but the array is now sorted in numeric order, enabling ranked analysis or visualization without any external enrichment.
