Authentication

Protected operations accept an API key in this HTTP header:

Code
Authorization: Bearer <key>

Request a free API key if you need one.

Authorize a playground request

1. Open an operation in the API reference.
2. Open the Authorize control and enter your API key.
3. Add the operation parameters, then select Send.
4. Clear the credential when you finish, especially on a shared device.

Send the key from your application

Keep the key out of source code by storing it in an environment variable:

Code
export CBBD_API_KEY='your-api-key'

Then pass it in the bearer header:

Code
curl --get 'https://api.collegebasketballdata.com/games' \
  --data-urlencode 'season=2024' \
  --data-urlencode 'team=Duke' \
  --header "Authorization: Bearer ${CBBD_API_KEY}"

The official Python, TypeScript, and R clients use the same bearer contract. The R package stores the key securely with keyring; the other clients receive it through their client configuration.

Protect the key

Treat an API key like a password. Do not commit it, place it in a URL, or include it in a public browser application. Use environment variables or your deployment platform's secret storage, and add the header from server-side code.

If the API returns 401, confirm that the key is current and the header starts with Bearer , including the space. Clear and re-enter the key in the playground if needed.
