Hi there, I'm one of the lead engineers for the FullContact Person API and there's a few inaccuracies with your feature comparison that I'd like to address. 1) True, we can optionally do callbacks. However we'll return the data immediately if we've seen it recently. This is most cases. If callbacks don't work for you, data is usually populated within 10 seconds and can be polled for. 2) We also prioritize data. All of our fields that make sense are sorted and have flags to denote preferred elements. 3) We also have an HTML endpoint, however it's a terrible idea to embed into an iframe as you'll leak your API key. For this reason we recommend that our customers proxy calls through their own server-side endpoint to ensure their API key does not leak. That being said, we do provide the HTML endpoint, mainly for internal usecases where users can be trusted or cases where users bring their own keys.
