# Site Climate Rainfall Pattern

> Site Climate Rainfall Pattern is a paid API for AI agents from site-climate.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Returns monthly rainfall totals, wettest/driest months, and the Walsh-Lawler seasonality index for any geographic coordinates.

## 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 site-climate-rainfall-pattern-fb2b7603
```

Example prompt: What's the monthly rainfall breakdown for Nairobi, Kenya — which months are wettest and driest, how much rain falls each year, and how seasonal is the rainfall overall?

## When to prefer this

Choose this endpoint when you specifically need rainfall seasonality metrics (Walsh-Lawler index), monthly precipitation breakdowns, or wet/dry season classification for any global location. It is more focused than a general climate summary endpoint when rainfall patterns are the primary concern, and more detailed than a simple annual total lookup.

## Known failure modes

- Coordinates out of range (lat outside -90 to 90 or lon outside -180 to 180) result in a validation error
- Coordinates in open ocean or polar extremes may return degraded=true with limited or null data
- Missing required lat or lon parameters returns an error
- Data source unavailability may result in null monthly values with reasons array explaining the gap

## How this service works

Monthly rainfall totals for a location, wettest and driest months, and how seasonal the rain is (Walsh-Lawler index).

## Output

Returns a JSON object with monthly rainfall in mm for all 12 months, total annual rainfall in mm, the wettest month name, driest month name, lists of wet and dry months, a numeric Walsh-Lawler seasonality index, a seasonality class label, an aridity class, plus metadata including data source, attribution URL, and any caveats.
