# Solar Generation Observations — Keyed Dataset Comparison

> Solar Generation Observations — Keyed Dataset Comparison is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Compares two keyed datasets of solar generation observations (up to 200 records each) and returns local descriptive analytics highlighting differences between them.

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 solar-generation-observations-keyed-dataset-comparison-d1b2612e -d '<json body>'
```

Example prompt: Compare these two sets of solar generation readings — I have records for solar arrays group-a and group-b across dates in October 2026, with generation_kwh and irradiance_w_m2 values for each day, and I want a side-by-side descriptive comparison of the two datasets keyed by row_id.

## When to prefer this

Use this endpoint when you have two finite sets of solar generation records (up to 200 rows each) keyed by row_id and want a structured descriptive comparison — e.g. before/after, period-over-period, or array-vs-array — without needing forecasting, enrichment, or external data sources. Ideal for energy analysts, solar fleet operators, or data pipelines that need a quick comparative summary for a bounded observation window.

## Known failure modes

- Missing required fields (row_id, solar_array, date, generation_kwh, irradiance_w_m2) in any row causes validation error
- Exceeding 200 rows in either dataset returns an error
- Date values not matching YYYY-MM-DD pattern are rejected
- Mismatched row_ids between datasets may result in incomplete comparison
- Payment failure via x402 protocol blocks the request

## How this service works

Solar generation observations - Keyed dataset comparison: Keyed dataset comparison for Solar generation observations. Up to 200 supplied typed records. Local descriptive analytics; no enrichment or forecast. One of 25 new profiles across 20 shared operations in this industry. 0.01 USDC includes one bounded keyed dataset comparison report.

## Output

A bounded keyed dataset comparison report with local descriptive analytics showing per-key differences, summary statistics, and contrasts between the two supplied solar generation datasets (generation_kwh and irradiance_w_m2 across solar arrays and dates). No forecasting or external enrichment is included.
