# Energy Readings Daily Sum Series

> Energy Readings Daily Sum Series 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 daily sum aggregations (kWh or cost) across energy meter readings grouped by date, returning a bounded time-series of up to 200 records.

## 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-daily-sum-series-2220e65a -d '<json body>'
```

Example prompt: I have meter readings for meters group-a and group-b from 2026-10-01 to 2026-10-04 — can you sum up the kWh totals by day across those meters so I get a daily energy consumption series?

## When to prefer this

Choose this endpoint when you have raw energy meter readings with date and numeric values (kWh or cost) and need to compute daily aggregate totals as a time series. It is ideal for local, in-process aggregation without external dependencies, forecasting, or enrichment. Best suited for up to 200 records where the goal is a simple daily sum rollup across one numeric field per meter group.

## Known failure modes

- Input array exceeds 200 items — rejected with validation error
- Missing required fields (row_id, meter, date, kwh, cost) on any row — validation failure
- Date string not matching YYYY-MM-DD pattern — schema rejection
- Numeric values outside allowed range (±1,000,000,000,000) — validation error
- Empty rows array (minItems: 1 violated) — schema rejection
- Invalid field selector (must be 'kwh' or 'cost') — enum validation failure

## How this service works

Energy readings - Daily sum series: Daily sum series 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 daily sum series deliverable.

## Output

Returns a daily sum time series where each entry represents the total kWh or cost summed across all meter records for that date. The output is a bounded series of up to 200 data points, locally computed with data-quality processing and no external enrichment or forecasting.
