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-two-measure-correlation-49712207 -d '<json body>'
```

Example prompt: Can you run a two-measure correlation between kWh and cost for my energy meter data? I have readings from meters group-a and group-b across dates 2026-10-01 through 2026-10-04 with up to 4 rows.

## When to prefer this

Choose this endpoint when you have structured energy meter records with both kWh and cost fields and need a fast, bounded statistical correlation between those two numeric measures. It is ideal for up to 200 rows of local numeric computation with no external dependencies. Prefer it over general-purpose stats APIs when you already have the data formatted with row_id, meter, date, kwh, and cost fields and want a single correlation deliverable at low cost ($0.01 USDC per call).

## Known failure modes

- Empty rows array or missing required fields (row_id, meter, date, kwh, cost) causes validation error
- Exceeding 200 rows returns a schema violation error
- Invalid date format (not YYYY-MM-DD) triggers pattern mismatch
- Numeric values outside ±1,000,000,000,000 bounds cause rejection
- Insufficient non-null numeric pairs may yield undefined or degenerate correlation result

## How this service works

Energy readings - Two-measure correlation: Two-measure correlation 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 two-measure correlation deliverable.

## Output

Returns a bounded two-measure correlation deliverable quantifying the statistical relationship between kWh and cost values across the supplied energy meter records, including local numeric processing and data-quality indicators. No external enrichment or forecasting is applied.
