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 brokered response, a `status` field (e.g. 'ok'), and a `roi_proof` object showing the compression ratio percentage (e.g. 91.4%), indicating how much intelligence was packed into the response relative to raw data.
Example use cases
Discover MCP tool for data task
“I need to find an MCP server that handles CSV-to-JSON conversion — can you query the MCP gateway with that search term and tell me what comes back?”
Route A2A request via broker
“Send a GET request through the AgentDiet MCP gateway asking for available agents that can do sentiment analysis, and show me the results with the compression ratio proof.”
Single gateway for x402 API access
“Instead of integrating dozens of x402 APIs separately, query the MCP gateway with 'real-time stock price' to find and call the right API in one shot, paying $0.01 USDC on Base.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/mcp-gateway?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single brokered entry point into a massive catalog of MCP servers, x402 APIs, and A2A agents without integrating each individually. It is ideal for agents that need to discover and call capabilities dynamically, settle payments in USDC on Base atomically, and want compressed high-signal responses with ROI proof. Prefer alternatives if you need a free, unauthenticated, or non-crypto-payment-based API gateway.
Side effects
- Payment failure if USDC balance is insufficient or Base transaction fails
- Invalid input type (must be 'http') returns schema validation error
- Unsupported method returns enum error
- No matching MCP server found for query returns empty data
- Gateway timeout if downstream MCP server is unresponsive
- Malformed queryParams returns parsing error
