Example use cases
Inspect memoryapi.org agent capabilities
“Can you pull up the ERC-8004 registration file for memoryapi.org so I can see exactly which 28 MCP services it exposes and how the x402 payment config is set up?”
Reference ERC-8004 standard implementation
“I'm building an agent registration file and need a real-world example to follow — can you fetch the memoryapi.org ERC-8004 JSON so I can use it as a template for structuring my own agent identity and service list?”
Verify x402-compatible MCP service registry
“Can you grab the memoryapi.org agent registration JSON and show me how the x402 payment support is configured alongside the MCP services, so I can confirm what a complete compliant registry looks like?”
