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 the manifest of available services, and an roi_proof object including a compression_ratio_pct metric (e.g. 91.4%). The manifest describes the 31,390+ MCP servers, x402 APIs, and A2A agents accessible through the broker.
Example use cases
Discover available MCP server catalog
“Pull up the full agent manifest from the X402-BROKER so I can see which MCP servers are registered and what capabilities they expose.”
Audit gateway services before integration
“Get me the manifest from the agentdiet X402-BROKER gateway — I need to review all the A2A agents and x402 APIs it brokers before I wire it into my workflow.”
Check broker compression and ROI metrics
“Retrieve the agent manifest from the X402-BROKER at mcp-gateway.agentdiet.dev and show me the ROI proof and compression ratio stats it returns.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/agent-manifest?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to dynamically discover what MCP servers, x402 APIs, or A2A agents are available through the agentdiet broker before routing tasks. Prefer this over hardcoding tool lists when you need a live, up-to-date manifest with compression/ROI metadata. It is the right choice for agents bootstrapping their tool catalog or orchestrators that need to enumerate gateway capabilities programmatically.
Side effects
- Payment not received — endpoint requires $0.01 USDC payment via x402 protocol before responding
- Malformed input object — missing required 'type' or 'method' fields returns validation error
- Unsupported HTTP method — only GET and POST are accepted as method enum values
- Gateway unavailable — broker node may be temporarily offline, returning 5xx
- Invalid queryParams.url — if a URL is passed that is unreachable or malformed, lookup may fail
