API keys

Smallest AI uses API keys for authentication. You must include your key with every API request to authenticate your identity and track usage against your quota.

Each API key can be scoped to the following:

  • Rate Limits: Controls the number of requests allowed within a specified time period.
  • Credit Quota: Defines the maximum usage credits available for your account.

Your API key is confidential and should be kept secure. Never share it with others or expose it in client-side code (browsers, mobile apps, github repositories, etc.).

​
Making Requests

All API requests require your key in the Authorization header using the Bearer key format:

Authorization: Bearer YOUR_API_KEY

​
Example API Request

Test the API with this curl command by replacing YOUR_API_KEY with your actual key:

curl 'https://waves-api.smallest.ai/api/v1/lightning/get_voices' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_API_KEY'
