# Saylor Innovations Data Desk – NOAA Station Climate History

> Saylor Innovations Data Desk – NOAA Station Climate History is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Returns historical daily or monthly weather data for a NOAA GHCN station, including high/low/mean temperatures, precipitation, snowfall, hottest day, wettest day, and heating/cooling degree days

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 saylor-innovations-data-desk-noaa-station-climate-history-c9d7d39b
```

Example prompt: Pull the historical daily weather data for NOAA station USW00094728 (Central Park, NYC) from 2024-01-01 to 2024-06-30 — I want the high, low, and mean temperatures, total rainfall, and which days were the hottest and wettest.

## When to prefer this

Choose this endpoint when you need structured historical climate data — temperatures, precipitation, degree days — for a specific NOAA GHCN weather station by station ID. It is ideal when you already know the station ID and want summarized statistics alongside a full time series. Prefer alternatives if you need real-time or forecast data, if you need to search for stations by location (this requires a known station ID), or if you need data from non-NOAA sources.

## Known failure modes

- Invalid or unknown NOAA station ID returns an error or empty result
- Date range with no available data for the station returns an empty series
- Malformed date format (not YYYY-MM-DD) causes a parameter error
- Requesting very long date ranges may return incomplete data depending on station record availability
- Station may have missing observations for certain days, resulting in null values in the series

## How this service works

Historical daily or monthly weather for a NOAA station - high, low and mean temperature, rain, snow, wettest day, hottest day and heating and cooling degree days

## Output

A JSON object containing the station ID, name, latitude, longitude, requested date range, data source, and two main sections: a summary object (hottest day, coldest day, wettest day, mean high/low in Celsius/Fahrenheit, total precipitation, snowfall, heating/cooling degree days) and a time series array of daily or monthly records with individual temperature, precipitation, and degree-day values.
