How RSFlowHub Text & Language APIs APIs work, what they return, and where they fit in your product.
RSFlowHub Text & Language APIs provide a multi-model REST gateway for high-throughput natural language processing tasks including multi-lingual translation across 50+ languages, context-aware grammar correction, recursive document summarization, and regex-free PII masking. All endpoints return a consistent JSON envelope, route requests across multiple AI providers with automatic fallback, and never use your text to train AI models.
Showing 5 live endpoints with dynamic model failover, strict JSON contracts, and unified credit billing.
Detect user intent from natural language messages for routing, support, and workflow automation.
