## 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 climatepulse-historical-weather-probability-for-events-c8193ee1
```

Example prompt: What are the historical odds of clear, rain-free weather in Austin, Texas on June 14 — I'm planning an outdoor evening wedding reception and need to know how risky that date is.

## When to prefer this

Use this endpoint when a user needs historical climate probability for a specific future date and location — particularly for outdoor event planning, wedding venues, festivals, or travel decisions where knowing the statistical likelihood of certain conditions matters more than a short-term forecast.

## Known failure modes

- Invalid or unrecognized location returns 400 error
- Date outside supported historical range returns 400 or empty result
- Missing required parameters (location or date) returns 422 validation error
- Location too remote or lacking historical data returns empty or low-confidence result
- Network timeout on Vercel cold start returns 504

## How this service works

Global climate and weather intelligence API. Open-Meteo real-time weather + AI synthesis. Severe weather assessment, air quality monitoring, wildfire smoke tracking, agricultural grow-day modeling, climate comparison, event weather planning, and hyper-local forecasts. Covers 195 countries with 1km resolution weather data. Serves individuals, agricultural operators, event planners, outdoor recreation agents, and climate-sensitive businesses.
