Inspiration

The rising rates of homeless population, increased cost of food and living in general definitely pushed us to create a project that could actually have an impact on people's lives regardless of their background, but we were definitely mostly aiming to help the less fortunate/needy.

What it does

Provides free/highly discounted meals from popular fast food chains and restaurants by taking advantage of customer rewards programs

How we built it

Spent many hours using chrome dev tools to access private, undocumented api endpoints to find ones with unencrypted payloads that we could use to make our own api requests. Used react for frontend, mongo and node for backend and DB

Challenges we ran into

We spent hours trying to scrape mobile api endpoints, but we werent able to because the school wifi made it impossible to use tools such as burp suite, mitm proxy, or charles proxy because the way the network is set up prevented us from being able to monitor our phone's network activity and use our laptops as proxies, so we had to resort to manually finding and reversing api's using chrome dev tools to identify payloads.

Accomplishments that we're proud of

Successfully found and utilized numerous undocumented, private api endpoints after hours of searching, created react forms to submit our own post requests using our express backend to create accounts that will generate free food vouchers for top fast food chains such as whataburger, dennys, buffalo wild wings, and more. We are able to overcome countless of hours that were wasted by trying to unsuccessfully use tools like mitm proxy (the school's wifi prevented it from working) and were able to come out with the working project we had wanted to make since the beginning of the hackathon.

What we learned

A lot about how to work with apis, specifically undocumented ones, how to troubleshoot different tools, how private networks work, and more

What's next for Quickserv

Hopefully continue revising our web app and eventually host it so that it can be used by everyone, and also add more restaurants so that people can get the most out of our product!
