# opendata402 NOAA Buoy Observations

> opendata402 NOAA Buoy Observations is a paid API for AI agents from opendata402.com, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-15).

Returns the latest meteorological and oceanographic observations from a NOAA National Data Buoy Center (NDBC) station by 5-character station ID.

## Facts

- Endpoint: GET https://opendata402.com/v1/buoys?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/opendata402-noaa-buoy-observations-d439f425

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 opendata402-noaa-buoy-observations-d439f425
```

Example prompt: What are the current conditions at NOAA buoy 46026 off San Francisco — wind speed and direction, wave height, and water temperature?

## When to prefer this

Use this endpoint when you need real-time, observation-level marine and coastal weather data tied to a specific NDBC station ID — ideal for sailing, surfing, fishing, offshore operations, or marine forecast applications. Prefer this over general weather APIs when you need ocean-specific variables like wave height, wave period, and sea surface temperature that terrestrial weather services do not provide.

## Known failure modes

- Invalid or non-existent station ID (not matching 5-character alphanumeric pattern) returns an error
- Station exists but has no recent data (offline or malfunctioning sensor) may return null fields or an error
- Some stations only report a subset of variables — missing fields for wave data on non-wave-reporting stations
- Network timeout if NOAA data feed is temporarily unavailable
- Payment failure if x402 USDC balance is insufficient

## How this service works

Latest observation from a NOAA National Data Buoy Center station (US and international buoys and coastal stations): wind direction and speed, gusts, wave height and period, air and water temperature and pressure. Use it for sailing, surfing, offshore work and marine forecasts. Station id e.g. 46026 (San Francisco), 41001 (Cape Hatteras).

## Output

Returns a JSON object with the most recent observation from the specified NDBC station, including wind direction (degrees), wind speed and gust (knots or m/s), wave height (meters), dominant wave period (seconds), air temperature (°C), sea surface water temperature (°C), and atmospheric pressure (hPa), along with station metadata and observation timestamp.
