Stats and player data from the TETR.IO Tetra Channel API

AUTH NONECORS ✓AGENT ✓HTTPS ✓COMMERCIAL ?

The Tetra Channel API exposes TETR.IO's public numbers — global user counts, games played, and per-player records. Responses ship with cache windows the docs ask you to honor. Note the CORS header only allows tetr.io itself, so browser calls from other origins are blocked.
