How RSFlowHub works
Production-grade AI gateway designed for deterministic machine-to-machine integrations.
Direct System Definition
RSFlowHub is a developer-first REST microservice platform that standardizes access to modern large language models. Rather than writing prompts and parsing unformatted text completions, developers call specialized endpoints (such as intent detection, sentiment analysis, email workflow generation, and translation) that return clean, structured JSON envelopes. Requests usually complete in 1 to 3 seconds, fail over to a backup AI provider automatically, and are billed through atomic credit pre-authorization so you are never charged for failed calls.
Core Production Integration Rules
Never let HTTP clients wait forever, but allow 60 seconds: a call can wait for the AI and then try a backup model. The official SDKs use this default.
Retry 429 and transient 5xx errors with randomized jitter to eliminate thundering herd storms.
Credits are verified upfront and decremented atomically upon completion. Zero billing on validation failures.
