The direct free API allows 10 requests per hour per IP.
A burst of automated lookups can reach the published limit quickly; higher-volume use requires a RapidAPI plan.

Overview
Robtex is a web-based service for looking up DNS records, IP addresses, autonomous systems, and related network infrastructure. Its API exposes many of these lookups programmatically.
Its documented scope does not match general-purpose web scraping. The closest directory category is Cybersecurity Software because the service supports infrastructure and threat-research workflows.
Robtex — What Sets It Apart?
These are the product-specific differences that may matter when deciding whether the software fits your workflow. They are based on documented evidence rather than a universal ranking.
- Combines forward and reverse DNS searches with historical relationship lookups for IP addresses, nameservers, and mail servers.
- Offers both browser-based investigation and programmatic access through a REST API and MCP integrations.
