I don't like being negative on HN - but this doesn't feel like a good faith Show HN.
The product isn't available to use - it baits you into putting your email address in but then just tells you that you've been added to a waitlist.
Secondly, there are so many APIs like this. There are a few that are reliable and have been around for years - but there is an endless churn of new ones created, barely maintained and then abandoned. What is different about this one? There doesn't seem to be anything new about it or any specific reasons to think it isn't just yet another cloned SaaS product being "growth hacked" on HN.
