Developer FAQ

Frequently Asked Questions

Technical specifications on Text & Language APIs latency SLAs, concurrency limits, schema validation, and billing.

Which languages are supported by the Text & Language APIs?

RSFlowHub Text & Language APIs support over 50 major global languages including English, Spanish, French, German, Japanese, Chinese, Hindi, Arabic, and Portuguese with automatic source language detection.

How are credits deducted for Text & Language APIs?

Standard NLP text calls consume 1 base credit per request up to 2,000 input characters. Longer text batches automatically calculate predictable tiered credit usage with full pre-authorization locking.

Does RSFlowHub store or train models on our submitted text?

No. All Text & Language endpoints operate under an ephemeral zero-retention policy. Your text payloads are processed in volatile memory and discarded immediately upon response delivery, ensuring HIPAA and GDPR compliance.

Can I customize the formality or tone of translated text?

Yes. You can pass the optional formality parameter ("formal", "informal", "professional") to instruct the translation engine to adapt pronouns, honorifics, and vocabulary according to your target audience.

What is the average response latency for real-time text processing?

Text & Language endpoints maintain an average sub-180ms round-trip latency via our globally distributed edge gateway infrastructure with automated circuit-breaker failover.
