Forget searching for an online translation api free that don't require authentication. Get the security, quality, and scalability your business needs.
While seemingly easy, APIs without authentication pose major security risks. They lack quality control, offer no support, and cannot handle complex formats or terminology. For professional use, a secure, authenticated API is essential.
Most free, non-authenticated APIs are not suitable for business use. They often have strict usage limits, poor translation quality, and no data privacy. Smartcat offers a free tier with a secure API, providing a professional alternative.
Our API supports over 80 file formats, including developer-specific ones like JSON, XML, YAML, and RESX. It also handles documents, marketing files, and subtitles, preserving all original formatting.
The API connects to your centralized Smartcat account. This includes your translation memories and glossaries. Every translation automatically uses your approved terminology for brand consistency.
Smartcat offers flexible pricing, including a free forever plan for individuals and small teams. Paid plans scale with your usage, offering significant cost savings over traditional translation methods through AI automation.
Our AI learns from every edit made by your team or our vetted linguists. This feedback loop continuously refines the AI's output for your specific context, improving accuracy and style with each project.
Yes. A single API call can trigger translations into all your target languages simultaneously. This parallel workflow dramatically accelerates time-to-market for global launches.
