Retrieve NOAA Weather Alerts API

What it does

NOAA Weather Alerts lets you fetch active weather alerts for a specified area using a two-character region code. Send an area query value and, optionally, a limit to control how many alerts are returned.

Use it when you need current hazard or warning data for a U.S. state or similar area code in a workflow, dashboard, or notification system. For example, you might poll for active alerts before showing a local weather panel, triggering internal safety messages, or routing location-specific updates to users.

The request is simple: area is required and must be exactly two characters, and limit defaults to 100 with a maximum of 500. The response is a JSON object whose shape is not further constrained in the schema, so you should treat it as a structured alerts payload and read the fields documented by the API response itself.

NOAA Weather Alerts is a practical fit for applications that need timely weather status by region without building a separate feed parser.

  -H "apy-token: $APY_TOKEN"

What you'll get back

Returns a JSON object with the alert response. The schema doesn’t declare any specific fields, so the exact top-level properties may vary.
