Send your token as a Bearer token in the Authorization header on every request:
This is the only supported authentication method. Requests without a valid token receive a 401 Unauthorized response.

​
Example

Tokens are issued by Compute Index (david@compute-index.com). They are long-lived — treat them as secrets and never commit them to source control.

​
Access scopes

API keys are scoped. A key is granted a subset of prices, metadata, and transactions access; index endpoints follow the same scope model. If a request returns 403, your token is missing the required scope — contact support to adjust it.
