TLD SLA Compliance

Independent ICANN Spec 10 monitoring. Cross-check measurements with diverse global probes at matching cadence.

Global Probe Network

DNS every 60s, RDAP/WHOIS every 5m. RFC 3161 timestamped evidence. MoSAPI-compatible exports for apples-to-apples comparison.

Domain Intelligence

RDAP data enriched with historical changes, registration patterns, and cross-referenced entity information.

High Availability

Mirrored authoritative data with automatic updates. Never blocked by rate limits or upstream outages.

mTLS Authentication

Client certificate authentication ensures only your applications access the API.

Bulk Access

Download complete datasets for offline analysis. IANA bootstrap files, root zone data, TLD registries, and more.

Independent SLA Monitoring

ICANN measures registry compliance, and their word is final. Our platform provides independent measurements you can cross-check against ICANN's findings. We match their exact cadence (DNS: 60s, RDAP/WHOIS: 5m) so you can speak at their level.

When ICANN says your DNS was slow at 14:32 UTC, you can compare with independent probes measuring the same thing at the same time. Export in MoSAPI-compatible format for apples-to-apples comparisons. RFC 3161 timestamps for legal-grade evidence.
