  Custom API-key signature. Every restricted call is signed: take the current Unix
  epoch as `ts`, compute the HMAC-SHA1 of `ts` keyed by the account private_key, and
  send that as `api_sig` alongside the public `api_key`. The public/private key pair
  functions as username/password and is generated on the account API settings page.
  A few Service endpoints (language_pairs, languages, unit_count) require only api_key.

  description: Public API key identifying the account. Every authenticated call must also include
    `ts` (Unix epoch) and `api_sig` (HMAC-SHA1 of `ts` keyed by the account private key). Keys
    are created on the account API settings page.
