Show HN: Rubick, Data API and Search API for commonly used datasets

Hi all, I am looking for feedback.

I am launching Rubick, a free Data API & Search API service for commonly used datasets such as countries, currencies, cities, etc.

My goal is to make it easier for developers to build applications that involve 1.) users entering their country / city, and 2.) users filtering any content by country / city.

The latest datasets are as follows:

- ISO 3166 Countries

- ISO 4217 Currencies

- UN M49 Areas

- PHL Areas

- PHL Postal Codes / Zip Codes

All of these documented at http://docs.rubick.io.

I'm looking to add USA areas & USA postal codes soon.

The Data API lets you access the entire datasets. For example, https://api.rubick.io/iso/countries will give you all the ISO-recognized countries.

The Search API lets you search through the datasets. For example, https://search.rubick.io/iso/countries?q=usa will give you the list of countries matching the "usa" query.

Some of my thoughts:

- Do you find something like this useful?

- Currently I'm offering both the Data API and the Search API for free, but the Search API (powered by TypeSense) can be overloaded with a lot of users since it's just hosted on a small server. Do you think people will be willing to pay for scalability (e.g. having it on better servers, for search-as-you-type service)?

Thank you.
