Will this work for SSR applications? e.g. think old school net or jsp apps which make network requests then receive HTML which then needs to be parsed in order to understand the key pieces of information and then additional network requests? I've found it relatively straight forward to reverse engineer SPA requests however with server side rendered apps, yow would your service handle that?

Good question. Finding the request that's responsible for the action you want will be a bit trickier for SSR, but it's still possible for most cases. It auto-generates regex (for now) to parse out needed info out of the html template.

Another thing I've seen is that some of these old school apps are sending certain requests that don't modify the page but set server side context which subsequent requests are dependent on.

For example, set context to a particular group and then subsequent navigation depends is filtered on that group even though the filter is not explicit on the client side but due to state stored in the session remotely.

This can also have implications on concurrency for a given session where you need to either create separate sessions or make sure there is some lock on particular parts of server side state.

Would this type of this eventually be possible? Or at least hooks in able for us to add custom code such as session locks

I just noticed over the weekend new Claude agreed to reverse engineer a graphql server with introspection turned off, something Im pretty sure it would have refused for ethical reasons before the new version it kept writing scripts, i would paste the output, and it would keep going, until it was able to create its own working discount code on an actual retail website The only issue with these kinds of things is break…

We are working on a way to auto-patch internal APIs that change by having another agent trigger the requests. Regarding the legality aspects — really appreciate you mentioning this — we’ve put a lot of thought into these issues, and it’s something we’re continually working on and refining. Ultimately, our goal is to allow each developer to make their own informed decision regarding the policies of the platforms that…

I have to disagree, it is definitely not legal in the US to use unauthorized access points to access authorized data. Thats like saying you're allowed to get into your apartment through breaking your neighbors door and climbing between the windows

In the US this is pretty simply covered by Computer Misuse Act and Computer Fraud and Abuse Act, both federal laws

Im not claiming you're liable, just surprised no lawyer pointed this out at YC

Really digging this idea. I've spent plenty of time trying to dig into the network tab to automate requests to a website without an API. Cool to see the process streamlined with LLMs. Wishing you all the best of luck!

Thank you!

Hell yeah! Love to see this launch. We have spent a lot of time at Wren recently trying to reverse engineer some local law APIs to help make renewable energy developer lives easier (less parsing through hundreds of PDFs, dead links, etc.) -- going to try this out and see if it can speed up our workflow.

Thank you! Would love your feedback after you use it!

Wow this is great! I think this is kind of the future of automation and "computer use" once LLMs become powerful enough.

Every task on the web can be reduced down to a series of backend calls, and the key is extracting out the minimal graph that can replicate that task.
