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 DEX listing information, a `status` field (e.g. 'ok'), and an `roi_proof` object including a `compression_ratio_pct` value (e.g. 91.4%), indicating the efficiency of the broker's intelligence compression.
Example use cases
Discover available MCP tools via broker
“Can you check the X402-BROKER DEX to see what MCP servers and tools are currently available for routing, and give me a summary of what's listed?”
Agent routing intelligence lookup
“I need to find which x402 APIs and A2A agents are accessible through the agentdiet broker gateway — can you pull the DEX data and tell me what's there?”
Verify gateway status and compression metrics
“Pull the DEX endpoint from the X402-BROKER and tell me the current status and ROI proof compression ratio it returns.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/dex?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to discover or route across MCP servers, x402-compatible APIs, or A2A agents through a unified broker gateway that settles micropayments in USDC on Base. It is best suited for agents that need directory-style lookups of available tools and services in the x402/MCP ecosystem, especially when cost-per-call efficiency matters (ROI compression). Prefer this over direct MCP server calls when you want centralized routing intelligence.
Side effects
- Missing or malformed `input.type` or `input.method` fields return validation errors
- Invalid token query parameter may return empty or unauthorized data
- Payment failure in x402 flow (0.01 USDC not settled) blocks access
- Service unavailability on the Base network may cause gateway errors
- Empty `data` object returned if no DEX entries match the query
