MiCodigoPostal.Fun
The Chilean postal code lookup that should already exist.
The problem
Looking up a postal code in Chile is harder than it should be: the official search sits behind an anti-bot wall, exposes no API, and goes down. I built the opposite — fast, bilingual, with a public API that needs no key — and above all honest about precision: when it only knows the commune-level code it says so, instead of inventing an exact one it does not have.
Status
It is free, I fund and build it myself, and I don't monetise it. It's a hobby project for the community: I made it because the problem had no quick solution and because I wanted to put what I know into something fun. It covers all 346 communes in the country with a page each, and anyone can use its API without signing up.
