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 workflow result, a `status` field (e.g. 'ok'), and a `roi_proof` object including a compression_ratio_pct metric indicating efficiency of the routed call.
Example use cases
Discover best MCP tool for task
“I need to scrape and summarize a product page — search through your connected MCP servers and route my request to whichever tool handles web extraction best.”
Route agent pipeline request
“My agent needs to call an external data enrichment service. Search the available x402 APIs and A2A agents for an enrichment workflow that accepts a company name, then execute it.”
Find and run code execution workflow
“Look across your 30,000+ connected MCP servers for one that can run a Python snippet and return the output — find the best match and execute it for me.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/workflows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single unified gateway to discover and execute across thousands of MCP servers, x402 APIs, and A2A agents without managing individual connections — especially when micropayment settlement in USDC on Base is required and you want deterministic routing with ROI telemetry.
Side effects
- No matching MCP server or workflow found for the query — empty data returned
- Payment settlement failure on Base USDC — transaction not completed
- Invalid input schema — missing required `type` or `method` fields
- Upstream MCP server or A2A agent timeout or unavailability
- Query too vague to route deterministically — ambiguous or null result
