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

TETR.IO: common questions
Is TETR.IO free to use?

Does TETR.IO need an API key?

Is TETR.IO up right now?
As of our last scheduled check, TETR.IO is unmonitored. We re-probe it every sweep — the status badge and uptime chart above always show the latest.
