## 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-robotics-smart-contract-aggregator-mcp-node-1c1d6d23 -d '<json body>'
```

Example prompt: Search the M2MCent robotics smart contract aggregator node for information about autonomous robot smart contract deployments and give me the result URL.

## When to prefer this

Choose this endpoint when you specifically need to query the M2MCent robotics and smart contract aggregator MCP node for robotics-domain smart contract data and are prepared to pay ~$1.17 USDC per call via x402 on Base L2. Avoid if you need free lookups, non-robotics domains, or if the boolean 'url' response schema raises reliability concerns.

## Known failure modes

- Payment failure — insufficient USDC balance for $1.17 x402 settlement
- Query field missing — returns 400 if 'query' is not provided
- No matching results — returns a null or empty URL if no aggregator data found
- Network timeout — MCP node may be temporarily unavailable
- Schema mismatch — 'url' field typed as boolean in schema may indicate unreliable response structure

## 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 in the schema, though likely a URL string in practice) pointing to the aggregated robotics/smart contract result resource.
