RSFlowHub Unified AI Microservice Architecture

Production-grade AI gateway designed for deterministic machine-to-machine integrations.

Automatic Provider Fallback

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

5-Second Timeout

Never allow HTTP clients to block indefinitely. Set a 5s client-side timeout to protect thread pools.

Exponential Jitter Backoff

Retry 429 and transient 5xx errors with randomized jitter to eliminate thundering herd storms.

Pre-Auth Credit Locks

Credits are verified upfront and decremented atomically upon completion. Zero billing on validation failures.

Frequently Asked Technical Questions

RSFlowHub is a platform of ready-made AI APIs. Each endpoint (intent detection, sentiment analysis, translation, moderation, email and ticket automation, data extraction and more) takes a JSON request and returns a structured JSON result, running on models from OpenAI, Google Gemini, DeepSeek and xAI Grok with automatic fallback. Usage is billed in credits, with a free plan to start.

All requests require header authentication using the x-api-key HTTP header (or Authorization: Bearer <API_KEY>). Keys are hashed with SHA-256 for maximum security and can be rotated instantly via the developer dashboard.

RSFlowHub prevents unexpected overdrafts and billing race conditions using atomic pre-authorization locks. Before executing your request, the gateway verifies that your account has the base credits required. If the request is rejected during validation (422) or is malformed (400), no credits are charged.

Most requests complete in 1 to 3 seconds depending on input length and model; identical repeats on cache-enabled endpoints return faster. A circuit breaker retries failed provider calls on a backup model. Use a 15 to 30 second client timeout and exponential backoff with jitter for retries.
