Regarding the order book data of the NBA prediction market on Polymarket, has any fren encountered similar issues?
Recently, when trying to obtain the Ask 1 price, I found that Cloudflare's protection mechanism imposes certain restrictions on data scraping. Some data aggregation services have reported that they cannot penetrate the platform's firewall and can only rely on delayed API interfaces to get market data. The problem is that this creates a noticeable time difference between the Last Price and the price displayed in real-time on the website.
For traders who engage in high-frequency trading or seek data accuracy, this delay can indeed affect decision-making. Is there currently a way to obtain more real-time order book data? Or how is everyone handling this issue?

Ha, this wall from Cloudflare is indeed annoying, it's a tough problem for us.

A latency of a few hundred milliseconds directly kills high-frequency trading, which is why Large Investors are looking for ways to build their own Nodes.

I think instead of stubbornly fighting for data sources, we should consider whether we can reach an agreement through API vendors with Polymarket.

To be honest, the barriers to market data are getting higher and sometimes it's faster to just look at the web Order Book.
---
Cloudflare's protection logic is nothing new, the key is that Poly itself hasn't provided a formal data cooperation channel.
---
Have you asked if anyone is using VPNs or proxies to request in rotation? Although it feels like a temporary solution.

If we really want to do high-frequency trading, we might as well switch to those more open prediction markets, why stick to just this one?
