Frequently Asked Questions

Everything you need to know about integrating and using Multilingual AI Translation API.

RSFlowHub APIs are standard RESTful endpoints. You can call them from PHP (Laravel, Symfony), Python (Django, FastAPI), JavaScript/Node.js, Go, Java, C#, or plain cURL.

Our Translation API operates at sub-200ms latency on average, backed by our 99.95% SLA uptime infrastructure.

Yes! The API intelligently identifies HTML markup (e.g., <strong>, <a href="...">), Markdown elements, and variable placeholders (e.g., {user_name}, :count), preserving them intact while translating only human text.

Translation requests consume 1 base credit per call for standard payloads under character limits.

Absolutely. All API traffic is encrypted using HTTPS/TLS 1.3. Payload data is processed in memory and never stored or used for public AI model training.
