Why is Uniblock cheaper?

No duplicate fees from overlapping provider services—one subscription with Uniblock gives you everything you need. With the Enterprise Plan, you get tailored pricing that scales with your project, ensuring cost efficiency as you grow.

How does Uniblock ensure reliability compared to using a single provider?

Uniblock is built with redundancy at its core, ensuring continuous uptime through automatic provider failover. Requests are intelligently routed to the best-performing provider in real time, and if one becomes unavailable, Uniblock seamlessly switches to a backup without disruption.

Why should I choose Uniblock over other providers?

Uniblock gives you access to data across 120+ networks in one place, without the hassle of managing multiple subscriptions. With just one plan, you get a cost-effective solution that scales as your project grows, backed by a unified API that makes data more accessible than ever. On top of that, our dedicated customer service ensures you get the support you need, with the flexibility to request new features or data sources as your requirements evolve.

How is Uniblock faster than other providers?

Uniblock aggregates data across multiple providers and uses intelligent routing to always connect you to the fastest one in real time. For high-performance needs, we also operate dedicated nodes that deliver data with ultra-low latency, ensuring your applications run smoothly without delay.

If I’m already using other providers, how easy is it to switch to Uniblock?

Migration is simple—just move your existing provider keys into Uniblock and manage all your requests from one place. Our routing system automatically handles traffic across providers, so you keep your existing access while gaining smarter management and the added benefit of Uniblock’s full data coverage.

What if I can’t find the API, chain, or provider I need on Uniblock?

Simply let us know—we take requests and can quickly add new APIs, chains, or providers to our network. Our flexible infrastructure and responsive team ensure you get the coverage you need as your project evolves. Contact us: support@uniblock.dev.
