## 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 robotics-smart-contract-validator-mcp-7baa8e0b -d '<json body>'
```

Example prompt: Can you validate this robotics smart contract text to check if it passes: 'contract RobotFleet { address owner; function deploy(uint robotId) public returns (bool) { ... } }'?

## When to prefer this

Use this endpoint when you need a lightweight pass/fail boolean validation of robotics-focused smart contract text, especially within automated pipelines or agent workflows where a simple true/false gate is sufficient. Prefer it over more expensive or verbose contract auditing tools when you only need a quick validity signal rather than detailed feedback.

## Known failure modes

- Missing required 'text' field returns a schema validation error
- Empty or malformed contract text may return score: false without explanation
- Network or payment settlement failure may prevent execution
- Ambiguous or non-contract text input may yield unreliable boolean results
- x402 payment failure results in 402 HTTP response before execution

## 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 single boolean field 'score' — true if the submitted smart contract text passes validation, false if it fails.
