Tournament API

The Tournament API is a public API that enables Tournament Organizations (TO) to more effectively use rewind.lol.

Signup and Verification

1. You must be (or represent) a current tournament organization for League of Legends. Individuals not representing a TO as a staff member will be denied access to the API. Using a tournament organization’s API key for personal purposes may result in access termination.
2. You will be asked to provide evidence of:
   • previous tournament history
   • upcoming events
   • active participation by members
   • rules of participation and/or terms of service
3. Once approved, you may be required to join the Patreon “Tournament API Access” tier to satisfy the setup fee. Ongoing Patreon membership is not required after the setup fee is paid.
4. A key will be manually issued within 1 business day. A tentative quota will be set based on the frequency and size of tournaments.
5. A representative from your tournament organization must remain in the rewind.lol discord server.

API Service

2. All API responses are in JSON format.
3. All API requests require a ?api_key= query parameter.

4. Some API requests incur a quota cost. If there is not enough quota remaining to complete a request, there will be a 400 status response.
5. Issued API keys are permanent and belong solely to the tournament organization they were issued to.
6. If reasonable care is not taken to secure issued API keys, access may be suspended.
7. If the assigned API key becomes compromised, please notify iaace immediately for issuance of a new key.

API Quota

1. If the quota approaches 0, please reach out to iaace for an increase/reset. There is no fee associated with quota increases.
