Google's Indexing API has very clear usage rules:

"The Indexing API can only be used to crawl pages with either JobPosting or BroadcastEvent embedded in a VideoObject."

To use Warpindex, you need to add the service as an owner to your Google Search Console account. Warpindex then uses the Indexing API in a prohibited manner:

"Warpindex {...] works by using our own web crawlers and certain Google tools like the Search Console and Indexing API.

[...]

Now, Google recommends using the Indexing API mainly for specific types of content like job postings or events, but it can handle other pages too, as long as there aren't any technical SEO issues. We've been using it for a while now without any problems." Source: https://help.warpindex.com/en/articles/21-how-does-warpindex-work-is-this-magic

Warpindex is lying to users. Google EXPLICITLY PROHIBITS using the Indexing API for any purpose except indexing the two types of listings shared above.

Multiple users have asked Shirin, the founder, to explain this contradiction in the Questions section. She has ignored these questions for days and cannot give a satisfactory answer. The Indexing API is not meant to be used the way Warpindex uses it.

I bought Tier 5 and will be refunding my purchase as soon as I submit this review. Use this tool at your own risk.
