```

Example prompt: Send my request data through the grandmaster API gateway MCP and process the following payload: 'initiate task sequence alpha for workflow coordination'.

## When to prefer this

Choose this endpoint when you need to route or process agentic requests through an MCP-compatible grandmaster API gateway, particularly in multi-agent architectures where a central coordination layer is required. Best suited for workflows that require a gateway intermediary to dispatch, transform, or coordinate tasks.

## Known failure modes

- Missing or empty 'data' field returns a validation error
- Malformed request body causes a 400 Bad Request
- Payment not included or invalid x402 payment header results in a 402 Payment Required
- Gateway timeout if downstream processing takes too long
- Internal gateway error (500) if the grandmaster routing layer fails
