# Solar Generation Observations – Numeric Row Ordering

> Solar Generation Observations – 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 2026-10-14).

Sorts up to 200 solar generation observation records by a chosen numeric field (generation_kwh or irradiance_w_m2) and returns the ordered rows as a local descriptive analytics report.

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-numeric-row-ordering-95062317 -d '<json body>'
```

Example prompt: Sort these 4 solar array observations by generation_kwh: row-1 on 2026-10-01 for group-a had 10 kWh and 1 W/m², row-2 on 2026-10-02 for group-b had 20 kWh and 2 W/m², row-3 on 2026-10-03 for group-a had 15 kWh and 3 W/m², row-4 on 2026-10-04 for group-b had 30 kWh and 4 W/m².

## When to prefer this

Choose this endpoint when you have a batch of solar generation or irradiance observations (up to 200 rows) and need a simple numeric sort/ranking with no external enrichment, forecasting, or aggregation — purely local descriptive reordering of supplied data at minimal cost ($0.01 USDC).

## Known failure modes

- Empty rows array returns a validation error (minItems: 1)
- More than 200 rows submitted triggers a maxItems violation
- Invalid date format (not YYYY-MM-DD) causes schema rejection
- Missing required fields (row_id, solar_array, date, generation_kwh, irradiance_w_m2) causes record-level validation failure
- Invalid field enum value (not 'generation_kwh' or 'irradiance_w_m2') returns an error
- Payment of 0.01 USDC not provided results in 402 Payment Required

## How this service works

Solar generation observations - Numeric row ordering: Numeric row ordering 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 numeric row ordering report.

## Output

Returns the submitted solar generation observation rows reordered numerically by the specified field (generation_kwh or irradiance_w_m2), providing a locally sorted descriptive view with no external enrichment or forecasting applied.
