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.

ABA Bank Routing Number API Zyla Labs may have a lot of APIs, but their business practices are unprofessional and unethical. A year ago I purchased a 1-year subscription to an ABA Routing number API. Bad on me for not doing more research, but their data was very outdated. I emailed asking when their data would be updated and they never replied. My lack of research makes losing my initial subscription fee my fault. I found another much more accurate API and abandoned the Zyla Lab API. The next time Zyla Labs contacted me was a single email with both an invoice for renewal and a receipt for charging me for another year’s subscription. Within hours I asked them to cancel my subscription and refund my money. They responded stating they could not issue a refund because "Those are the terms and conditions you accepted when you created an account with us". Charging in this manner seems very unethical to me. Had they sent their renewal invoice a day, week, or month in advance (like most ethical companies who automatically renew subscriptions), I would have unsubscribed prior to the renewal. If you have alternatives for using another API provider, I recommend steering away from Zyla Labs. Their business practices and policies do not have your best interests at heart.

The support was great.So hope to get… The support was great.So hope to get more days for free trial)

Routing Number Lookup API API provides a good value. Online chat support (Lester) was very helpful!

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.
