# x402-factory.com Weather Window Forecast

> x402-factory.com Weather Window Forecast is a paid API for AI agents from x402-factory.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Summarizes a ≤12-hour time window at a coordinate into decision-ready weather numbers (rain probability, precipitation, temp range, max gust, comfort index) plus a plain-English verdict.

## 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 x402-factory-com-weather-window-forecast-afb63ebb
```

Example prompt: What's the rain probability, temperature range, comfort score, and overall verdict for the area around 47.6062° N, 122.3321° W this Sunday from 10:00am to 4:00pm Pacific time — I need to decide whether to hold an outdoor market there.

## When to prefer this

Use this endpoint when you need a compact, decision-ready weather summary for a specific short time window (≤12 hours) at a precise coordinate, and want a pre-computed comfort index and plain-English verdict rather than raw hourly data. Prefer this over general weather APIs when building event, delivery, or travel planning agents that need a binary go/no-go signal with supporting numbers in a single call.

## Known failure modes

- Window exceeds 12 hours — endpoint may reject or truncate
- Invalid or out-of-range lat/lon coordinates return a 400 error
- start datetime after end datetime causes validation failure
- Datetime format not ISO 8601 with timezone returns schema error
- Payment of 0.02 USDC not completed via x402 returns 402 Payment Required
- Location over ocean or polar region may have reduced forecast quality
- Future window beyond forecast horizon (e.g. >10 days out) may return low-confidence results

## How this service works

One-call answer for a specific time window: rain odds, temps, comfort, verdict — Summarizes a ≤12-hour window at a coordinate into decision-ready numbers (rain probability, expected precip, temp range in °C, max gust, comfort index) plus a one-sentence plain-English verdict. Built for agents planning events, deliveries, and travel.

## Output

Returns a JSON object with rain_probability (0–1), expected_precip_mm, temp_range with low and high in °C, wind_max in km/h or m/s, comfort_index (0–1), an array of severity_flags (e.g. 'high wind', 'heavy rain'), and a one-sentence plain-English verdict summarizing the window, plus meta information about the forecast.
