Authentication

Every request to the Chariot API is authenticated with an API key sent in the chariotai-api-key header.

curl https://api.chariot.in/v1/credits \
  -H "chariotai-api-key: YOUR_API_KEY"

Generate and manage keys from the Chariot dashboard. A key is bound to your workspace, so requests draw on that workspace’s credits and plan limits.

Treat your API key like a password. Anyone with it can spend your credits. Keep it server-side, store it in a secret manager or environment variable, and never put it in client-side code or version control. If a key leaks, rotate it from the dashboard.

Authentication errors

All authentication failures return 401 with the standard error envelope:

{
  "statusCode": 401,
  "error": "UnauthorizedException",
  "message": "No API key or user credentials provided"
}

Message	Cause
`No API key or user credentials provided`	The `chariotai-api-key` header is missing.
`Invalid API Key or user credentials`	The key is unknown or malformed.
`API Key expired`	The key has passed its expiry.

See Errors & status codes for the full envelope and other status codes.

Which endpoints accept API keys

API keys authenticate the public product endpoints: text-to-speech, voices, and account credits. Dashboard actions such as account signup, billing, and workspace administration are handled in the Chariot web app and are not part of this API.
