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 with a 'data' field containing the grounded web search results, a 'status' field ('ok' on success), and an 'roi_proof' object containing a compression_ratio_pct value (e.g. 91.4%) indicating how efficiently the web content was compressed for the agent.
Example use cases
Real-time fact checking for AI agent
“I need you to ground your answer with live web data — look up the current status of the SpaceX Starship launch program and tell me what's happened in the last week.”
Live market data retrieval
“Search the web right now for the current Bitcoin price and any major crypto news from today, then summarize what you find.”
Current events lookup for research
“Find me up-to-date information on the EU AI Act implementation timeline — I need grounded, real web results, not your training data.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/realtime-web-grounding?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs real-time, grounded web data and you want to pay per call in USDC via the x402 protocol without managing API keys. It is especially useful in agentic pipelines that require verified, compressed web context with a compression proof, or when integrating with x402-compatible infrastructure on Base. Prefer it over static knowledge bases when recency and verifiability matter.
Side effects
- Missing or empty 'query' parameter returns no results
- Payment failure (insufficient USDC on Base) blocks the request with HTTP 402
- Invalid 'type' field (must be 'http') causes schema validation error
- Network or upstream web fetch failure returns non-ok status
- Rate limiting if too many requests are made in a short window
