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 response payload from the routed MCP/x402/A2A backend, a 'status' field (e.g. 'ok'), and an 'roi_proof' object that includes a compression_ratio_pct indicating how much token bloat was stripped (e.g. 91.4%).
Example use cases
Discover and call a web-scraping MCP tool
“I need you to query the MCP mesh to find and run a web scraping tool on https://example.com/products and return the structured data — use a GET request with that URL as the query.”
Agent-to-agent task delegation
“Delegate this summarization task to the best available A2A agent in the mesh: 'Summarize the top 5 AI news stories from this week' — route it as a GET request and bring back the result.”
Unified x402 API access for tool use
“Query the broker mesh for real-time Bitcoin price data — send it as a GET request and pay the $0.01 fee, then give me whatever the top-ranked x402 API returns.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/mesh?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an agent needs to access a broad catalog of MCP servers, x402-gated APIs, or A2A agents through a single unified gateway without managing individual connections or payment channels. It is especially suited when the target capability is unknown or must be discovered dynamically from a large pool. Prefer it over direct API calls when you want automatic routing, token compression (85-97% HTML bloat reduction), and micropayment settlement handled transparently in USDC on Base.
Side effects
- Payment failure: USDC payment on Base not confirmed, resulting in 402 rejection
- Invalid input type: 'type' must be 'http', other values rejected
- Unsupported method: only GET and POST are accepted
- No matching backend: query finds no suitable MCP server or x402 API in the mesh
- Backend timeout: downstream MCP server or A2A agent does not respond in time
- Schema violation: missing required 'type' or 'method' fields returns validation error
