x-api-key
string

required

The OneBalance API uses API keys to authenticate requests. All API requests require authentication using an API key passed in the x-api-key header:

curl -X 'GET' \
  'https://be.onebalance.io/api/path-to/endpoint' \
  -H 'x-api-key: ${ONEBALANCE_API_KEY}' \
  ...

A public API key is available for testing purposes with limited usage: 42bb629272001ee1163ca0dbbbc07bcbb0ef57a57baf16c4b1d4672db4562c11.

All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without authentication will also fail.

Learn how to generate API access tokens at OneBalance Docs.
