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 status 'ok' and a data object containing ASN-related network information for the queried domain, plus a roi_proof field indicating compression ratio metadata from the gateway.
Example use cases
Identify hosting provider for a domain
“Look up the ASN for shopify.com — I want to know which network or ISP is hosting their infrastructure.”
Security investigation of suspicious domain
“Can you check what autonomous system number is behind suspicious-domain.xyz? I'm trying to figure out who operates that network.”
Competitive infrastructure research
“Find the ASN info for stripe.com — I want to see which network operator they rely on for their routing.”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/asn-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick ASN/network ownership lookups for domains and are already operating within the x402/USDC micropayment ecosystem on Base. It is best suited for agents doing network intelligence, security research, or infrastructure analysis that need ASN data without setting up a dedicated WHOIS or BGP data provider.
Side effects
- Missing or invalid domain query parameter returns an error
- Domain does not resolve to a known ASN returns empty data
- Payment not settled in USDC on Base results in 402 response
- Malformed input schema (missing required 'type' or 'method' fields) causes validation error
- Rate limiting or quota exceeded on the gateway
