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 m2mcent-climate-tech-zk-proof-synthesizer-mcp-node-95396f8e -d '<json body>'
```

Example prompt: Can you synthesize a zero-knowledge proof for my climate tech dataset using the M2MCent ZK proof synthesizer node — pass in my parameters string with the emissions data payload?

## When to prefer this

Choose this endpoint when you need to perform zero-knowledge proof synthesis specifically for climate technology data and are operating within the x402 payment protocol ecosystem on Base L2. It is appropriate when privacy-preserving verification of environmental or sustainability data is required and you can afford the ~$1.42 USDC per call cost.

## Known failure modes

- Missing or malformed 'parameters' string results in 400 validation error
- Insufficient USDC balance or x402 payment failure results in 402 Payment Required
- Invalid ZK proof input parameters may return computation error
- Network latency or node unavailability on Base L2 may cause timeout
- Unexpected response schema mismatch — url field returns boolean rather than a URL string

## 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 'url' field (boolean) indicating the result of the ZK proof synthesis operation. Note: the schema is minimal and the actual meaningful output may be a URL or status reference delivered through the x402 payment-gated response.
