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 aggregated response from matched MCP servers or agents, a 'status' field ('ok' on success), and an 'roi_proof' object including a compression_ratio_pct value indicating how much the response was optimized (e.g. 91.4% compression).
Example use cases
Discover MCP tools for a task
“Search across the entire MCP server network and tell me which tools can help me extract structured data from PDFs — I want the best options available.”
Unified agent capability query
“Query the A2A mesh and find me any connected agents or APIs that can translate text to Spanish — pull from all available MCP servers and give me a consolidated answer.”
Route task to best available API
“I need to run a sentiment analysis on some customer reviews — search the MCP gateway mesh and find the best available service that can handle this, then route my request through it.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/a2a-mesh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to fan out a query across a large ecosystem of MCP servers, x402 APIs, or A2A agents without knowing which specific service to call. It is ideal for discovery-plus-execution workflows where the agent doesn't have a predetermined tool and wants the mesh to route to the best available capability. Prefer this over direct API calls when you want aggregated, deduplicated intelligence from thousands of sources with built-in micropayment handling via USDC on Base.
Side effects
- No matching MCP server or agent found for query — returns empty data object
- Payment settlement failure on Base network — USDC transaction may not confirm
- Invalid input type or method enum — schema validation error
- Query too vague to route deterministically — may return generic or low-relevance results
- Rate limiting or quota exceeded — 402 payment required again or request rejected
