API Authentication

  • All APIs require an API Key, which must be included in the HTTP request header using the field API-Access-Key.
  • Each API Key can have specific permissions configured. By default, no APIs are accessible. Ensure the API Key has the appropriate permissions before making a request.
  • The request frequency for any single node must not exceed the maximum allowed access rate for that node within a given time period. Violating any rate limit will result in error code 429.
