Well-Documented API Hat | Developer Humor Cap | Geekpsters
The rarest artifact in software development. Rarer than a bug-free deploy. Rarer than a meeting that could have been an email.
A well-documented API. Someone actually wrote it down. Examples that run. A changelog that tells you what broke and why. Error codes that mean something. You found one, and now you're wearing a hat about it.
This cap is for the engineer who has been burned by Swagger files that lie, by "self-documenting code" that documents nothing, by TODO comments from 2019 still tagged to a developer who left the company. You know what good looks like. You've just rarely seen it.
What you're getting
- Structured cap with adjustable strap — fits most head sizes
- Embroidered or printed front panel
- Print-on-demand — made to order, not batch-manufactured
- Ships within 3–5 business days
Fit & sizing
One size adjustable. The back strap fits most head circumferences. Low-profile structured brim — the kind of hat you wear to your desk and also to the coffee shop where you're debugging in public.
Care
Spot clean preferred to maintain shape. If machine washing, use a cap cage or mesh bag on a gentle cold cycle. Air dry only — reshape while damp. Do not put in the dryer.
Shipping & returns
Dispatches within 3–5 business days. Delivery typically 7–14 business days depending on your location. Printed to order — please check the size guide before purchasing as we can't accept size-based returns.
Why Geekpsters?
We're print-on-demand, which means zero overstock and no wasted inventory. Every hat is made when you order it. Ethical by design — for the developers who care about what's under the hood.
