## 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-8ac066a1 -d '<json body>'
```

Example prompt: Can you validate this robotics smart contract hash for me: 0xabc123def456... and tell me if it's legitimate before we proceed?

## When to prefer this

Use this endpoint when you need a fast, on-demand boolean validation of a robotics smart contract hash before allowing automated or robotic systems to execute contract-driven actions. Prefer this over manual blockchain queries when you need a simple valid/invalid signal without parsing raw chain data.

## Known failure modes

- Missing or malformed hash input returns an error
- Invalid hash format not recognized by the validator returns false or an error
- Payment failure via x402 protocol results in 402 response and no validation result
- Network timeout or node unavailability returns a service error
- Hash referencing an unknown or unregistered contract returns false

## 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 indicating whether the provided contract hash is valid (true) or invalid (false).
