Thanks for your question. Indeed, ipdata is a competitor. We have published a recent blog post that compares them with our solution:

As a summary, you get responses in less time (our API is at least twice faster), more data points (company name, domain, IP type, security field is_cloud_provider). Our client libraries have support for caching. We provide a dashboard to check your usage and edit settings. Last but not least, you pay only for what you use lookup by lookup!
