# Sustainable LLM Leaderboard Oracle MCP

> Sustainable LLM Leaderboard Oracle MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Retrieves or computes sustainability-focused rankings and metrics for large language models (LLMs) based on energy efficiency, carbon footprint, and performance tradeoffs.

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 sustainable-llm-leaderboard-oracle-mcp-a1cad903 -d '<json body>'
```

Example prompt: Which large language models rank highest on the sustainable LLM leaderboard right now, and what are their energy efficiency or carbon footprint scores?

## When to prefer this

Use this endpoint when you need sustainability-focused LLM benchmarking data — particularly energy efficiency, carbon footprint, or green AI rankings — rather than general capability or accuracy leaderboards like MMLU or HellaSwag scores.

## Known failure modes

- Vague or unrecognized model name returns empty or partial results
- Leaderboard data may be stale if not frequently updated
- Overly broad queries may return generic rankings rather than targeted comparisons
- API returns an error if the data field is missing or malformed

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns leaderboard data including LLM sustainability rankings, energy efficiency metrics, carbon footprint estimates, and performance-per-energy scores for one or more models based on the input query.
