Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/rdap-lookupWhen to prefer
Use this endpoint when you need authoritative registrar and registration date data directly from RDAP (the modern replacement for WHOIS) for a specific domain — ideal for trust scoring, compliance audits, phishing investigation, or domain operations pipelines where structured, machine-readable output is required.
Side effects
- Domain not found in RDAP — returns error or empty record
- Invalid domain format — request rejected with validation error
- RDAP registry timeout — upstream lookup failure
- Domain uses a registry with no RDAP support — partial or no data returned
- Rate limit exceeded — 429 response
