Summary
In today's episode, I explain how to navigate bot detection and website blockers when building production AI agents. Here's what this means for you. You can build more resilient agents by treating web access as an infrastructure challenge rather than an AI intelligence issue. You'll also learn these concepts: how specialized libraries like Playwright help navigate blockers, why official APIs offer a more reliable alternative to scraping, and how hosting local datasets improves application performance.
Key Takeaways
- You'll learn why bot detection acts as an infrastructure hurdle that requires specific tools like Playwright rather than just smarter AI
- You'll discover how requesting specific libraries like curl_cffi or Tor nodes enables your agents to bypass web protections
- You'll see how prioritizing official APIs and local datasets provides faster insights and more reliable data access

In today's episode, Resa asks how are production AI agents dealing with bot detection, specifically being blocked by things like Cloudflare or Data Dome. It depends. It depends on how you've set up your agencings. There are a number of libraries such as curl CFFI that can help navigate those kinds of things. They're not perfect.
That's all it's doing. It's firing up a browser. So the browser itself has to be something that can deal with things like uh bot blockers, etc. And that's not something AI can help you with. That is something that you have to.
That's an infrastructure thing that is separate from the AI agent. And so there's the obviously you have browser-based tools and systems like playwright and all sorts of things that have the ability to at least somewhat block uh deal with those things. There are um there are tools, there are ways to build things like jitter into your tools. Uh, if you know to ask your uh coding agent to do that, it will do that. Claude code will do that.
Um the catch is you have to know what to ask for. Out of the box, your average coding tool, whether it's clawed code, quen code, whoever, your average tool is not going to know uh the kinds of specific things that you are trying to get around. So knowing what to ask for, knowing to ask for the curl C FFI library, knowing to ask for playwright, knowing to ask for Tor nodes, that's something you have to provide. If you do that, you will get very good performance. Now, here's the thing even with all that, you are still looking at, at least based on uh projects I've done recently, uh a quarter to a third of sites will simply not let your AI agent have access to their data.
And that's okay. Uh that's their right. Those places have a right to protect their data. And so the question that you have to then ask is is that data that you're after available in some other place or location? So if it's commodity data, um, which means that it's you know publicly available data or common data sets, um, there's probably another repository somewhere out there on the web that has that information that does not require scraping, or even better, has an API.
That's the the ideal is have a place, have something that has an API that you can register for that you can use, and obviously you have to stay within terms of service. Uh, a real good example of this is there's a lot of economics data, uh, some of which is paywalled or or firewalled, whatever, but the providers also provide a copy of it to the Federal Reserve Bank of St. Louis. They have the Federal Reserve Economic Database called Fred, and Fred is uh free to use. You can get an API key, so you can use it legitimately, no scraper needed.
You connect to the Fred uh systems, and then you are good to go with close to 200,000 different data series. There are other things, uh data repositories out there that may not have APIs but allow you to download a copy of the data as a data set. Uh, and then the obligation would be on you to refresh that data set from time to time, but um that's better than not having the data at all. And because it's a local data set that you're uh presumably going to host, asuming it's not like you know, eight petabytes, then you have no latency in your application. No latency means a better, faster user experience, uh it means faster insights and things, so that's a that's a win for you too.
So, to summarize that you can use detection libraries and stuff to identify and sometimes work around uh protections that people have put on their websites. However, you are better off uh uh finding sources of data that you can access without needing to use those things if possible. And it's not always possible, and so you'll do the best we can with what you've got and uh give those libraries a try that I mentioned, see if they work for you. So, thanks for the question.
