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 nasa-power-solar-irradiance-meteorology-point-query-ec4b3eaa
```

Example prompt: Pull NASA POWER daily solar irradiance and temperature data for the coordinates 34.05°N, 118.25°W from January 1, 2023 to December 31, 2023, using the RE community and including ALLSKY_SFC_SW_DWN, T2M, and RH2M parameters.

## When to prefer this

Choose this endpoint when you need daily historical solar irradiance or meteorological data for a specific geographic point from NASA's POWER dataset, especially for renewable energy site assessments, agricultural climate analysis, or building energy modeling. It covers data from 1981 onward globally and supports multiple NASA POWER parameter groups. Prefer this over general weather APIs when you need NASA's satellite-derived solar radiation parameters (e.g. ALLSKY_SFC_SW_DWN, CLRSKY_SFC_SW_DWN, ALLSKY_KT) or when scientific rigor and long historical record are required.

## Known failure modes

- Date range exceeds 366 days — request rejected
- Start date before 1981-01-01 — historical data unavailable before this epoch
- More than 10 parameters requested simultaneously — request rejected
- Invalid lat/lon outside valid WGS-84 range — coordinate not found
- Invalid community code (not RE, AG, or SB) — parameter rejected
- NASA POWER upstream API unavailable — service timeout or 503
- Malformed ISO date format — validation error

## How this service works

Daily solar irradiance and meteorology at a coordinate from NASA POWER, for a date range of up to 366 days.

## Output

A structured dataset of daily values for the requested NASA POWER parameters at the specified coordinate, spanning the requested date range (up to 366 days). Each day includes numeric readings for solar radiation metrics (e.g. all-sky surface shortwave downwelling, direct normal irradiance, diffuse irradiance, clearness index), atmospheric variables (temperature, humidity, dew point, precipitation), and wind parameters (speed, direction), depending on the parameters requested.
