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 'data' field containing the routed response, a 'status' field ('ok' on success), and an 'roi_proof' object showing a compression_ratio_pct (e.g. 91.4) indicating efficiency of the routing result.
Example use cases
Discover capable MCP tool for task
“I need you to search through the MCP gateway index and find which server can help me summarize a PDF document — run a GET query for 'PDF summarization' and return what you find.”
Route financial data query to agent
“Use the AgentDiet MCP router to look up live ETH/USD price data — send a GET query for 'ETH USD price' and tell me the result.”
Find AI agent for code generation
“Query the MCP gateway index with 'Python code generation' using a GET request and tell me which agent or MCP server can handle that task for me.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/a2a-router?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single unified gateway to route queries across thousands of MCP servers, x402 APIs, and A2A agents without knowing in advance which backend to call. It is ideal for discovery-and-execute workflows, agent-to-agent brokering, or any scenario where you want deterministic routing with USDC micropayment settlement on Base rather than managing individual API integrations.
Side effects
- Payment not settled — USDC payment on Base failed or insufficient balance
- Invalid input type — 'type' field must be 'http'
- Missing required fields — 'input.type' or 'input.method' not provided
- Query not matched — no MCP server or agent found for the given query string
- Gateway timeout — downstream MCP server or agent did not respond in time
- Invalid method — method must be GET or POST
