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 status field ('ok'), a data object containing quote details, and an roi_proof object that includes a compression_ratio_pct value (e.g. 91.4%) indicating the efficiency of routing through the broker gateway.
Example use cases
Pre-flight micropayment cost check
“I'm about to route an agent call through the x402 broker — can you pull the USDC quote audit for a GET request to https://api.somemcp.com/search so I can see the ROI proof before committing the payment?”
Verify compression efficiency of gateway route
“Can you run a quote audit on a POST request to https://mcp-gateway.agentdiet.dev/v1/run and tell me what the compression ratio looks like in the ROI proof?”
Compare payment quote before A2A delegation
“Before my agent delegates a task to another agent via HTTP GET at https://agent.example.com/task, fetch the USDC quote audit so I can verify the cost and ROI data.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/usdc-quote-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to inspect or audit the USDC micropayment quote and ROI proof for a specific HTTP endpoint before committing to an x402 payment, especially when optimizing cost efficiency across many MCP server or A2A agent calls routed through the AgentDiet broker.
Side effects
- Missing required 'input' object returns validation error
- Invalid HTTP method (not GET or POST) returns enum error
- Malformed or unreachable target URL may return empty data or error status
- Payment not settled in USDC on Base may prevent access (402 response)
- Schema mismatch on input type (not 'http') causes rejection
