# Open Domain Data

> Open, versioned datasets describing the domain infrastructure ecosystem.
> Open Domain Data publishes structured datasets only. It does not rank
> registrars, recommend providers, or sell domains.

## What this project is
Open Domain Data is an open-source project that publishes machine-readable
datasets about domain registrars, registrar APIs, DNS capabilities, TLD
pricing, RDAP metadata and security contacts. Every record carries a
verification status, a source list and a timestamp.

## What this project is NOT
- Not a registrar.
- Not a domain marketplace.
- Not a ranking site. Open Domain Data does not score, rank or recommend
  registrars. Ranking products are maintained separately and must
  disclose how they use this data.
