# Storm Station 247 Radar/Forecast State-by-State Summary

> Storm Station 247 Radar/Forecast State-by-State Summary is a paid API for AI agents from stormstation247.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).

Returns a state-by-state statistical summary (highest value, location, range, and mean) for a chosen radar or forecast picture across the contiguous US and DC

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 storm-station-247-radar-forecast-state-by-state-summary-b0a9397c
```

Example prompt: Which states have the highest radar reflectivity right now, and where exactly in each state is the peak? Give me the full ranked list of the lower 48 using the reflectivity picture.

## When to prefer this

Use this endpoint when you need a ranked, state-level statistical digest of any of 31 radar or forecast products across the contiguous US — ideal for quickly identifying which states are most affected by a weather phenomenon without having to parse raw grid data or images. Prefer this over raw radar feeds when the goal is comparative state-level analysis rather than precise point or grid data.

## Known failure modes

- Missing required 'picture' query parameter returns an error
- Invalid enum value for 'picture' returns a validation error
- Radar data may be unavailable or stale if upstream NWS/radar feeds are offline
- Some picture types may have sparse or no data during certain seasons (e.g. snow totals in summer)

## How this service works

One radar or forecast picture read state by state: each state's highest value and where it stands, or its range and mean, highest first. This call needs picture, one of the 31 pictures the input schema names, as the radar page names them; the example below answers for real. Every address this endpoint serves is listed one at a time at https://stormstation247.com/api/x402.

## Output

A ranked list of the contiguous 48 states plus DC, each with the highest value for the requested picture type, the geographic location of that peak within the state, and (for continuous fields like temperature) the state's lowest value, highest value, and mean, ordered from highest to lowest.
