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
Returns a JSON object with a 'data' field containing the proxied service response, a 'status' field ('ok' on success), and an 'roi_proof' object including a compression_ratio_pct metric indicating how efficiently the response was delivered.
Example use cases
Fetch data from x402-gated API
“I need to query a paywalled x402 API endpoint — can you route the GET request through the AgentDiet broker, settle the $0.01 USDC fee on Base, and give me back the response data?”
Connect agent to remote MCP tool
“My agent needs to call a specific MCP server tool to get weather data — can you broker that request through the mcp-gateway, pay automatically in USDC, and return whatever the MCP server responds with?”
A2A task delegation with micropayment
“I want to delegate a subtask to a specialized A2A agent in the network — route the request through the AgentDiet alpha-stream broker, handle the USDC payment on Base, and bring back the agent's response with the ROI proof.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/alpha-stream?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to access any of 31,390+ MCP servers, x402 APIs, or A2A agents through a single unified gateway that handles USDC micropayment settlement automatically on Base. Prefer it over direct API calls when you don't want to manage x402, L402, or MPP payment handshakes yourself, or when you want deterministic routing and ROI proof alongside your response.
Side effects
- Insufficient USDC balance to settle the $0.01 micropayment on Base — returns payment required error
- Target MCP server or x402 API is unreachable or offline — returns error in data field
- Invalid or missing 'input.type' or 'input.method' fields — schema validation error
- Target service does not exist in the 31,390+ indexed catalog — not found response
- Network congestion on Base causing payment settlement delay — timeout or pending status
