Low quality results, predatory billing practices As mentioned by other commenters, I was charged after canceling my trial subscription. Support claimed it was not canceled and would not refund the payment. I canceled because the API results were very low quality.

Incredibly dissatisfied I feel compelled to express my deep frustration with my recent encounter with Zyla Labs and their Metals API integration on zylalabs.com. Unfortunately, my dissatisfaction stems from their handling of package modifications, which has left me incredibly dissatisfied. To provide some context, I wanted to increase the capabilities of my existing package. However, I was astounded to discover that Zyla Labs does not offer a straightforward option to upgrade my current package. Instead, they insisted that I subscribe to an entirely new package. This approach is perplexing and makes little sense. It is unreasonable to expect customers to maintain multiple packages when all they seek is an upgrade to their current one. Regrettably, this forced me into a situation where I now have two concurrent packages with Zyla Labs, which is both unnecessary and frustrating. But the issues do not end there. When I decided to cancel one of the packages, I encountered yet another setback. Zyla Labs promptly blocked my access to the API, even though I had already paid for a year's worth of service. Consequently, not only did I lose my investment for the entire year, but I was also denied access to the API.

Crooks with 0 empathy for loyal customers Have been customers with them for a number of years. When we wanted to upgrade our package to a higher package because we were at our limit we had to purchase a new package with a higher rate-limit. For this, our old package was not simply cancelled, so we had to pay twice the package. We immediately emailed about this asking to cancel the one package because we wanted to upgrade. Got the response that we should just read the terms and conditions and determine both packages. Most poor service I have ever seen from a company. No long term strategy for loyal customers and only think about making quick money.

Unethical Business Practices I had been a client for many years. The function was no longer needed for my business website. I chose to cancel my one year subscription on the same day it renewed. I was charged $399. Although I chose to cancel the same day it renewed I was told they could not refund me any portion of the money. I was paying one year in advance and was canceling on the renew date. Very unprofessional that a company would charge you for services not used or rendered. I would not recommend them based these practices.
