# Climate Tech ZK Proof Validator

> Climate Tech ZK Proof Validator is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $0.768746/call, status unknown (last checked 2026-10-10).

Validates zero-knowledge proofs related to climate tech data via a monetized MCP node using the x402 payment protocol

## Facts

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-tech-zk-proof-validator-fa1c1d0a -d '<json body>'
```

Example prompt: Can you validate this zero-knowledge proof for my climate tech dataset and tell me if it checks out?

## When to prefer this

Use this endpoint when you need to cryptographically validate zero-knowledge proofs specifically within the climate technology domain, and you require a pay-per-call model via USDC on Base L2 with no gas overhead. Prefer this over general ZK validators when the proof is tied to climate data, carbon credits, or environmental compliance attestations.

## Known failure modes

- Missing 'audio' field in request body returns validation error
- Malformed or non-ZK-proof input may return false hash result
- Payment failure via x402 protocol results in 402 Payment Required response
- Server-side proof verification error may return 500 Internal Server Error
- Invalid Base64 or encoding of the audio/proof field may cause processing failure

## 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 a JSON object with a 'hash' boolean field indicating whether the submitted zero-knowledge proof is valid (true) or invalid (false).
