# Severe Warnings in a Bounding Box

> Severe Warnings in a Bounding Box is a paid API for AI agents from agents.myradar.dev, paid per call via MPP, price unknown, status unknown (last checked 2026-10-12).

Returns severe weather warning polygons (with geometry, type, and timing) that fall within a specified geographic bounding box, with optional time filtering and pagination.

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 agents-myradar-dev-severe-warnings-in-a-bounding-box-b82ff9cb
```

Example prompt: Show me all severe weather warning polygons currently active within the bounding box from 45.0°N, 100.0°W in the upper left to 36.0°N, 88.0°W in the lower right — include up to 50 results.

## When to prefer this

Use this endpoint when you need severe weather warning polygons for a geographic region defined by a bounding box — ideal for map overlays, regional alert dashboards, or historical research across multiple warning areas. Prefer this over the point-based warning endpoint when you need to cover a broader area or display multiple polygon geometries simultaneously. Choose this over the watches/warnings/advisories (WWA) bounding box endpoint when you specifically want only severe warnings (not watches or advisories).

## Known failure modes

- Invalid or out-of-range latitude/longitude values in path parameters return a 422 validation error
- Swapped upper-left and lower-right corners may return empty results or unexpected geometry
- begin_time after end_time may return zero results or an error
- Very large bounding boxes may require pagination; without limit/offset, only the first page is returned
- No warnings in the area or time window returns count=0 and an empty results array
- Malformed datetime strings (wrong format) cause request failure

## How this service works

Returns the severe weather warning polygons within the box from the upper left to the lower right corner, optionally between begin_time and end_time (YYYY-mm-dd HH:MM:SS), paged with limit and offset.

## Output

A JSON object containing a count of warnings found, the limit and offset used, the total number of matching results (for pagination), and an array of warning objects each with geometry (list of lat/lon pairs), VTEC identifier, phenomenon type, and begin/end/issued/expires timestamps in YYYY-mm-dd HH:MM:SS format.
