# Energy Readings Base-100 Index Series

> Energy Readings Base-100 Index Series is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Computes a base-100 indexed series from up to 200 energy meter records (kWh or cost), normalizing all values relative to a chosen base row.

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 energy-readings-base-100-index-series-2342968d -d '<json body>'
```

Example prompt: I have 4 daily energy meter readings — meter group-a read 10 kWh on 2026-10-01, group-b read 20 kWh on 2026-10-02, group-a read 15 kWh on 2026-10-03, and group-b read 30 kWh on 2026-10-04 — can you generate a base-100 index series using the first row as the baseline and the kWh field?

## When to prefer this

Choose this endpoint when you need a local, deterministic base-100 normalization of energy meter records (kWh or cost) without any external API calls, forecasting, or enrichment. It is ideal for benchmarking consumption or cost trends relative to a specific reference row across up to 200 records. Prefer it over general analytics services when you want a lightweight, bounded, reproducible index computation at low cost ($0.01 USDC per call).

## Known failure modes

- Input array is empty or exceeds 200 rows — validation error
- base_index references a row position outside the supplied array bounds
- Base row value is zero or null, making division undefined — arithmetic error or null result
- Date strings do not match YYYY-MM-DD pattern — schema validation failure
- kWh or cost values exceed allowed numeric bounds — rejected input
- field enum value is not 'kwh' or 'cost' — schema error

## How this service works

Energy readings - Base-100 series: Base-100 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 base-100 series deliverable.

## Output

Returns a base-100 indexed series for each supplied energy record, where the value at the chosen base_index row is set to 100 and all other values are scaled proportionally. Includes local data-quality processing flags per record. No external enrichment or forecasting is applied.
