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 'status' field (ok/error), a 'data' object containing discovered subdomain information, and an 'roi_proof' object including a compression_ratio_pct value (e.g. 91.4%) indicating how efficiently the data was compressed relative to raw output.
Example use cases
Security recon on company domain
“I need to map out all the subdomains of acmecorp.com for a security audit — can you run a subdomain scan and list everything you find?”
OSINT investigation on target site
“What subdomains exist under tesla.com? I'm doing open-source intelligence research and need to see the full subdomain landscape.”
Attack surface discovery for bug bounty
“I'm doing a bug bounty on bugcrowd.com — can you enumerate all the subdomains so I can identify potential targets?”
Technical details
Endpoint
GEThttps://mcp-gateway.agentdiet.dev/v1/subdomain-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, pay-per-use subdomain enumeration via a standardized x402/USDC micropayment flow — especially useful for AI agents that need programmatic DNS recon without managing API keys or subscriptions. Prefer it over manual DNS tools when building automated security pipelines or OSINT workflows that settle payments on Base.
Side effects
- Invalid or non-existent domain returns empty data or error status
- Missing required 'domain' query parameter results in validation error
- Unreachable or firewalled domain may yield incomplete subdomain results
- Rate limiting or payment failure (402) blocks the request
- Malformed input schema triggers 400 bad request
