# M2MCent IoT Smart Contract Synthesizer MCP

> M2MCent IoT Smart Contract Synthesizer MCP is a paid API for AI agents from api.m2mcent.com, paid per call via x402, $1.049363/call, status unknown (last checked 2026-10-10).

Synthesizes IoT smart contracts from a text description via a monetized MCP node using the x402 payment protocol on Base L2.

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-iot-smart-contract-synthesizer-mcp-8821c075 -d '<json body>'
```

Example prompt: Generate an IoT smart contract for a temperature sensor network that triggers automatic USDC payments when readings exceed a threshold — just describe it in plain English and synthesize the contract.

## When to prefer this

Choose this endpoint when you need to rapidly synthesize IoT-specific smart contracts from natural language descriptions and want gasless USDC settlement via the x402 protocol on Base L2. It is particularly suited for agents operating in IoT-blockchain integration contexts where automated contract generation from text is the primary goal.

## Known failure modes

- Missing required 'text' field returns a 400 validation error
- Insufficient USDC balance or failed x402 payment returns a 402 Payment Required response
- Malformed or ambiguous text input may produce an unusable or empty contract output
- Network or node availability issues on Base L2 may cause timeouts
- Response schema inconsistency (url field typed as boolean) may cause downstream parsing errors

## 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 an object containing a URL (as a boolean in the schema, though likely a string in practice) pointing to the synthesized smart contract artifact or result resource generated from the input text description.
