Technical specifications on Text & Language APIs latency SLAs, concurrency limits, schema validation, and billing.
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.
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.
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.
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.
Text & Language endpoints maintain an average sub-180ms round-trip latency via our globally distributed edge gateway infrastructure with automated circuit-breaker failover.
