How this service works
Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.
Output
A JSON object with a status field ('ok' or error), a data object with authorization details, and an roi_proof object containing a compression_ratio_pct value (e.g. 91.4%) demonstrating the gateway's efficiency.
Example use cases
Verify agent wallet mint rights
“Check if my agent wallet address 0x1234567890abcdef1234567890abcdef12345678 has mint authority on the AgentDiet gateway before it tries to settle payments.”
Audit mint authority before deployment
“Before I deploy my new A2A agent, can you verify that address 0xdeadbeefdeadbeefdeadbeefdeadbeef00000001 is recognized as a mint authority on the x402 broker?”
Debug payment settlement failures
“My agent keeps failing to settle USDC payments — can you look up whether 0xaabbccddeeff00112233445566778899aabbccdd actually has mint authority on the AgentDiet MCP gateway?”
