# Site Climate - Climate Comparison by Coordinates

> Site Climate - Climate Comparison by Coordinates is a paid API for AI agents from site-climate.x402tookit.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-21).

Compare climate metrics side by side for two geographic locations, including temperature, rainfall, sunshine, wind, humidity, and Köppen classification.

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 site-climate-climate-comparison-by-coordinates-061a8f6a
```

Example prompt: Compare the climate side by side for London (51.5074, -0.1278) and Barcelona (41.3851, 2.1734) — I want to see temperature, rainfall, sunshine hours, humidity, wind, and their Köppen classes.

## When to prefer this

Use this endpoint when you need a direct, structured side-by-side comparison of climate conditions between exactly two geographic points. It is ideal for relocation decisions, travel planning, site selection (solar, agricultural, real estate), or any scenario requiring simultaneous multi-metric climate contrast. Prefer this over single-location endpoints when comparative analysis (warmer/wetter/sunnier) is needed in one call.

## Known failure modes

- Invalid or out-of-range coordinates return null values for climate fields
- Coordinates in ocean or uninhabited areas may return partial or null data
- Missing required query parameters (lat1, lon1, lat2, lon2) result in a request error
- Identical coordinates for both locations return identical metrics with no meaningful comparison
- Network timeout or upstream data source unavailability may return an error response

## How this service works

Compare the climate of two places by coordinates: temperature, rainfall, sunshine, wind, humidity and Koppen class side by side.

## Output

Returns a structured JSON object with climate metrics for both locations (mean temperature, coldest/warmest month, annual rainfall, peak sun hours, wind speed, humidity, elevation, and Köppen class), plus a natural-language summary, a list of reasons explaining the comparison, and binary indicators of which location is warmer, wetter, and sunnier. An 'asOf' timestamp and data source are also included.
