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-robotics-metadata-indexer-mcp-node-0a89a07b -d '<json body>'
```

Example prompt: Search the M2MCent robotics metadata indexer for available MCP nodes matching my robotics automation query and return the results.

## When to prefer this

Choose this endpoint when you specifically need to query the M2MCent robotics metadata indexer MCP node (#949) within the AEO network, and you are comfortable paying ~$0.83 USDC per call via x402 gasless settlement on Base L2. It is best suited for agents that need indexed robotics metadata and are already integrated with the x402 payment protocol.

## Known failure modes

- Payment failure: x402 USDC payment on Base L2 not processed, resulting in 402 response
- Invalid parameters string: malformed or missing required 'parameters' field returns an error
- Node unavailable: the specific MCP node (subdomain 949) may be offline or rate-limited
- Status false: node returns status=false indicating the query found no results or execution failed
- Network timeout: Base L2 settlement latency causes delayed or dropped response

## 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 boolean 'status' field indicating whether the MCP node execution succeeded. Additional robotics metadata payload may accompany the status, though the schema only guarantees the status boolean.
