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 status 'ok', a data payload containing the agent card (capabilities, supported protocols, routing info), and an roi_proof block including a compression_ratio_pct value (e.g. 91.4%) indicating how efficiently the gateway compresses responses.
Example use cases
Discover available MCP server catalog
“Fetch the agent card from the AgentDiet broker gateway so I can see which of the 31,000+ MCP servers it can route my requests to.”
Inspect gateway protocol support
“Get me the agent card for the AgentDiet MCP gateway — I want to know which protocols it supports like x402, L402, MCP, and A2A before I wire it into my agent pipeline.”
Audit gateway capabilities before integration
“Retrieve the agent card metadata from the AgentDiet execution node at mcp-gateway.agentdiet.dev so I can verify its capabilities and compression performance before integrating it into our workflow.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/agent-card?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover the full capability profile and service catalog of the AgentDiet MCP gateway before routing agent tasks through it. Prefer this over manual documentation browsing when building automated agent pipelines that need to self-configure based on available tools. It is particularly useful when you want machine-readable metadata about supported protocols (MCP, x402, A2A, L402) and compression performance.
Side effects
- Payment not settled — gateway returns 402 if USDC payment on Base is not included or fails
- Invalid input type or method enum — schema validation error if 'type' is not 'http' or 'method' is not GET/POST
- Upstream gateway unavailable — may return 5xx if the broker node is down
- Malformed queryParams URL — may return error if the URL parameter is invalid
