Gateway GusVSTimeout Titan

Gateway Gus saysTest and explore APIs with tools like Postman, Insomnia, and curl.

Before writing client code, exercise an API directly. curl is the universal command-line client (curl -X POST -H ... -d ...). Postman/Insomnia give a GUI for building requests, saving collections, environments, and auth. They're how you learn an API, reproduce bugs, and document working calls for teammates.

Power-ups you unlock

curl: universal CLI client
Postman/Insomnia: GUI, collections, environments
Exercise an API before coding against it
Great for reproducing and documenting calls

Timeout Titan attacks — common mistakes

Debugging in app code instead of curl first
Hardcoding secrets into shared collections
Not saving working requests for the team
