Navigate big API responses
A real API response can run to thousands of lines. Paste it here to see it as an interactive tree: collapse the parts you don't need, expand the ones you do, and see each value's type and each array's length at a glance.
Click any key to copy its path, like $.data.users[0].email, ready for JSONPath queries, test assertions or code such as response.data.users[0].email. Switch to the text view for a formatted copy of the whole response.
