Error Codes

The API uses conventional HTTP response codes to indicate the success or failure of requests:

  • ◇401 - Invalid or missing API key
  • ◇400 - Invalid request parameters
  • ◇403 - API key valid but insufficient permissions or exceeded limits
  • ◇500 - Server error

Rate Limiting

API requests are subject to rate limiting based on your project's configuration. The limits are verified for each API key and project combination.

Caching

The API supports optional caching of translation results. When cache is set to true:

  1. ◇Before translation, the system checks for a cached version
  2. ◇If found, returns the cached translation
  3. ◇If not found, performs the translation and caches the result for future use
