Technical details
Endpoint
POSThttps://x402.agentutility.ai/subdomain-enumWhen to prefer
Use this endpoint when an agent needs to programmatically discover the subdomain landscape of a target domain — e.g. for security auditing, attack surface mapping, competitive intelligence, or OSINT. Prefer this over manual DNS brute-force tools when you need a single pay-per-call API with structured JSON output settled in USDC via x402.
Side effects
- Invalid or non-existent domain returns empty subdomain list
- Malformed domain input may return an error response
- Payment failure via x402 results in 402 response before processing
- Rate limiting or timeout for domains with extremely large subdomain spaces
- Private or heavily shielded domains may return incomplete results
