Hi,
We started to use Lets Encrypt for automatic certificate generation. Unfortunately we start to get close to rate limits [1], so we requested an increase. Apparently our use case isn't eligible for increased limits, as it wasn't approved (no response, so not declined either). So we started to look for an alternative.<p>Do you know other CA that provide API for certificate requests? It can be paid. The API doesn't need to be compatible with Lets Encrypt, but it would be nice.<p>Thank you!<p>1. https://letsencrypt.org/docs/rate-limits/
ACME (<a href="https://en.wikipedia.org/wiki/Automated_Certificate_Management_Environment" rel="nofollow">https://en.wikipedia.org/wiki/Automated_Certificate_Manageme...</a>) is still new, I don't believe any other certified CA implements it.<p>What is your use case? Maybe there's a better way.
Can I suggest that perhaps you could just start using alternative domains to avoid the rate limit?<p>Edit: also, how long since you requested the increase? They say it takes a few weeks.
