# Datakoot Current Weather (NWS/NOAA)

> Datakoot Current Weather (NWS/NOAA) is a paid API for AI agents from x402.datakoot.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-11).

Returns real-time weather conditions for a US location by latitude/longitude, sourced from National Weather Service stations.

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 datakoot-current-weather-nws-noaa-e1c5d975 -d '<json body>'
```

Example prompt: What's the current weather at latitude 36.1867, longitude -94.1288? I need the temperature, humidity, and wind conditions right now.

## When to prefer this

Choose this endpoint when you need real-time, official US weather observations (temperature, humidity, wind) for a specific geographic coordinate and want authoritative NWS/NOAA data. Prefer it over forecast APIs when you need what conditions are *right now* rather than what they will be. At $0.002 per call it is extremely cost-effective for spot checks; use the free MCP tier (100 calls/day) for development or low-volume agents.

## Known failure modes

- Coordinates outside the US (NWS coverage only) — may return no station data or an error
- Invalid latitude/longitude values (out of range) — likely a 400 or empty response
- NWS upstream outage — may return stale or no data
- Very remote US locations with no nearby stations — sparse or missing observations
- Payment failure on Base/x402 — call not executed, no charge

## How this service works

48 live public-data tools (security, packages, SEC filings, economy, FX, weather, domains, Federal Register, Base) for AI agents. $0.002 USDC per call on Base via x402, charged only on success. The same tools are free for 100 calls/day via MCP at <server>.datakoot.com/mcp.

## Output

Returns a JSON object with current conditions observed at the nearest NWS station, including: temperature (°F and °C), humidity (%), wind speed (mph), sky/weather description (e.g. 'Clear'), observation timestamp (ISO 8601), station identifier (e.g. 'KCXY'), and a human-readable location name. Data source is attributed to NWS/NOAA public domain.
