Hi, 
I have nextjs project and from this project I call binacne api public routes.
In local environment everything works fine but when I deploy it on vercel then binance api tells me 'Restricted access'(error 451).
Any suggestions ?

Binance blocks many cloud / datacenter IP ranges.

So Binance responds with:

> **451 – Restricted access**

This is Binance intentionally blocking server-hosted traffic

Why public routes still fail

Even though you’re calling **public Binance endpoints** (no API key), Binance still applies:

* Geo restrictions

* Datacenter / bot protection

* IP reputation checks

So **“public” ≠ “allowed from anywhere”**
