# Climate Risk Score by Coordinate (CMIP6-Derived)

> Climate Risk Score by Coordinate (CMIP6-Derived) is a paid API for AI agents from x402-endpoints.onrender.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Returns a composite climate risk score (0-100) for heat, drought, and extreme rainfall at a given coordinate, comparing a baseline period to a future horizon year using Open-Meteo CMIP6 projections.

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 climate-risk-score-by-coordinate-cmip6-derived-3864e3f2
```

Example prompt: What's the projected climate risk score for coordinates 48.85°N, 2.35°E by 2050 under the ssp585 high-emissions scenario — I need the composite heat, drought, and extreme-rain breakdown.

## When to prefer this

Use this endpoint when you need a fast, worldwide, single-coordinate climate risk score for future horizon planning (2030–2050), especially for real estate due diligence, ESG reporting, infrastructure siting, or any use case needing a composite heat/drought/extreme-rain index. Prefer this over raw meteorological APIs when you want a single interpretable 0–100 risk score rather than raw climate model outputs.

## Known failure modes

- Missing required lat or lon parameters returns a 400/validation error
- Horizon year outside 2030–2050 range may return an error or be clamped
- Coordinates in ocean or polar regions may have incomplete CMIP6 coverage and return null or degraded scores
- SSP scenario label is informational only — the underlying dataset is a single pathway so ssp245 vs ssp585 may not produce meaningfully different results
- Service on Render free tier may cold-start and time out on first request
- Payment not provided or rejected returns 402 Payment Required

## How this service works

Derived climate risk score from Open-Meteo CMIP6 projections — a composite heat/drought/extreme-rain risk score (0-100) by coordinate and scenario, comparing a baseline to a future horizon. Worldwide. Derived/heuristic, not an official rating; the underlying CMIP6 HighResMIP dataset is a single high-emissions pathway and does not differentiate SSP scenarios.

## Output

A composite climate risk score from 0–100 combining heat, drought, and extreme-rainfall risk components, computed by comparing CMIP6 HighResMIP baseline climate data to a future horizon year at the given lat/lon. Also returns the scenario label and coordinate used. Not an official rating — derived/heuristic from a single high-emissions pathway.
