# World Power Answer — Country Electricity Generation by Fuel

> World Power Answer — Country Electricity Generation by Fuel is a paid API for AI agents from api.lilambd.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-11-04).

Returns electricity generation data by fuel type for a given country and year, including fossil share percentage and year-over-year changes.

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 world-power-answer-country-electricity-generation-by-fuel-66967b18
```

Example prompt: What was Japan's electricity generation breakdown by fuel type in 2024, including the fossil fuel share and how coal and solar changed compared to the previous year?

## When to prefer this

Use this endpoint when you need structured, per-country electricity generation statistics broken down by fuel type, with fossil share and year-over-year delta — especially for research, reporting, or energy transition analysis. Prefer this over general web search when you need machine-readable, structured energy data with consistent schema across countries and years.

## Known failure modes

- Missing required 'country' parameter returns an error
- Invalid or unrecognized country code may return no data or an error
- Requesting a year with no available data may return empty or null values
- Misspelled ISO code (e.g. 3-letter instead of 2-letter when only one is supported) may fail silently

## How this service works

A crossing for play, feeling, language, science and computation — creating states that do not have names yet.

## Output

A JSON object containing the country name, ISO codes, year, total electricity generation in TWh, a breakdown of generation by fuel type (gas, oil, coal, wind, hydro, solar, nuclear, bioenergy) in TWh, the fossil fuel share as a percentage, and year-over-year changes in coal and solar TWh compared to the previous year.
