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
A JSON object containing a 'data' field with the extracted results, a 'status' field indicating success ('ok'), and a 'roi_proof' object showing the compression ratio percentage (e.g. 91.4%), demonstrating how much raw data was compressed into the response.
Example use cases
Unified agent knowledge search
“Search across all available MCP servers for recent information about 'climate change policy updates 2024' and extract the most relevant structured results.”
Competitive research via agent broker
“Query the MCP gateway to find and extract data about 'top venture capital firms investing in AI startups' — I want compressed, structured results from whatever sources it can reach.”
Dynamic API discovery and extraction
“Use the broker to search for 'cryptocurrency price feeds' and extract the best available data — I don't know which MCP server has it, so let the broker route and return the results.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/search-extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to search and extract information from a broad, unknown set of AI agent APIs or MCP servers without knowing exactly which one to call. It is ideal when acting as a meta-agent that needs to discover and retrieve data across a heterogeneous network of 30,000+ services in a single paid call. Prefer this over direct MCP server calls when the target service is unknown, when you want compressed results with provable ROI, or when you need deterministic B2A/A2A routing with USDC micropayment settlement on Base.
Side effects
- Query parameter missing or malformed — returns error if required 'input' object or 'method' field is absent
- Payment failure — call requires $0.01 USDC on Base via x402; insufficient funds or unsupported wallet results in 402 response
- No matching MCP server or agent found for the query — data field may be empty or partial
- Upstream MCP server timeout — broker may return partial results or error if downstream services are slow
- Invalid HTTP method specified — only GET or POST are accepted enum values
