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 'status' field ('ok'), a 'data' object containing search results, and an 'roi_proof' object that includes a compression_ratio_pct field (e.g. 91.4%) indicating how much the response was compressed relative to raw web content.
Example use cases
Real-time news lookup for agent
“Search the web for breaking news about the US Federal Reserve interest rate decision today and summarize the top results for me.”
Fact-checking current events
“I need you to look up whether Elon Musk made any public announcements about Tesla this week — search the web and tell me what you find.”
Research aggregation for a report
“Search the web for the top five AI startups that raised funding in Q1 2025 and pull together what you can find about each of them.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/web-search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs live web search results and operates in an x402/USDC micropayment environment on Base, especially when you want compressed, structured results with proof of value (compression ratio) rather than raw HTML. Prefer it over traditional search APIs when you need pay-per-call crypto-native billing without API key management, or when integrating with MCP/A2A agent pipelines that already use the AgentDiet gateway.
Side effects
- Payment failure or insufficient USDC balance returns HTTP 402 with payment instructions
- Missing or empty 'query' parameter may return an empty or error response
- Invalid 'type' or 'method' fields (must be 'http' and 'GET'/'POST') cause schema validation errors
- Network or upstream search provider outages may return a non-200 status
- Malformed input schema (e.g. extra properties) rejected due to additionalProperties: false constraint
