x-api-key

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.
