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 iot-smart-contract-synthesizer-mcp-fdd1a4e6 -d '<json body>'
```

Example prompt: Synthesize a smart contract for my IoT temperature sensor network using the M2MCent IoT smart contract synthesizer — the parameters are: trigger alert when temperature exceeds 75 degrees and log to chain.

## When to prefer this

Choose this endpoint when you need to synthesize or evaluate IoT-specific smart contract logic via a monetized MCP node with gasless USDC micropayment settlement on Base L2. Prefer it for IoT automation workflows requiring on-chain contract generation from device parameters.

## Known failure modes

- Missing required 'parameters' field returns validation error
- Malformed parameters string may result in processing failure
- Payment failure via x402 protocol results in 402 Payment Required
- Network timeout on Base L2 settlement
- Ambiguous or unsupported contract parameters may return false negatively

## 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

A JSON object containing a single boolean field indicating whether the smart contract synthesis or evaluation succeeded or the condition evaluated to true/false.
