Your API “Won’t Grow”? That’s How Outages Are Born.

There’s a dangerous sentence in API design: “Don’t worry, it won’t be that many records.”

That’s how unpaginated collection endpoints get shipped.

GET /users
Returns a JSON array.
No limit? No page? No cursor?

Works perfectly.

Until production data grows.

Then latency grows. Memory grows. Payload size grows.
And suddenly your “simple” endpoint becomes a scaling liability.

Rentgen flags this pattern automatically:
• GET endpoint
• JSON array response
• No pagination or limit parameters

It’s not a failure.
It’s a warning about future technical debt.

Because unbounded lists don’t break immediately.
They break when your product succeeds.

Fix it while it’s boring.
