Any good Google Indexer with Refund Credits?

I'm creating a lot of links and I need to index them.

You are going to say to create T2 links for the backlinks, but I don't want to leave some footprints, because my links are harder to get and easy to create, and that would be like doing the hard work for my competitors.

The best indexer is indexmenow[.]com but too expensive $1 per link.

I also like SinByte but the problem is that they do not refund credits if link does not index.

I've heard some good news of PrimeIndexer but the problem is that they do not credits back if the link does not index.

Any recommendation?

speedyindex still refunds credits for unindexed links and pricing's way cheaper than indexmenow

Rapid URL Indexer.It‘s much cheaper and refunds credits if indexing fails, though I also prefer IndexMeNow because it tells the exact reason why it failed.

Indexer-wise, OneUpdater has been the most reliable for me. Their credit-back system actually works if URLs fail. Speed Links is another option but their support is slow. Honestly though, for small batches the free GSC URL inspection + request indexing method works fine. Just make sure your content is genuinely unique or Google will ignore the request.
