Sumo API

Sumo-API is a free, regularly updated resource for exploring Grand Sumo data, supporting fans, developers, games, and news sites. Its comprehensive database covers the sport from 1958 to the present, including current active rikishi and historical match results. Through its API and dashboard, users can access information about wrestlers, tournaments (basho), rankings (banzuke), schedules (torikumi), tournament records (hoshitōri), winning techniques (kimarite), and more.

The service lets users examine rikishi rankings, measurements, and shikona changes over time, compare head-to-head results, and review tournament or individual wrestler match records. It also provides kimarite usage statistics, including counts and the most recent recorded use. API and webhook guides help users work with the data, while the platform’s dashboard offers an accessible way to explore it.

Sumo-API data powers a range of third-party sumo games, statistics tools, and news sites. The project welcomes suggestions for additional data and features, and invites users to contribute toward its ongoing server and maintenance costs.
