Why Developers Build on RSFlowHub

Stop fighting raw LLM formatting inconsistencies, unexpected upstream vendor downtime, and separate billing accounts.

Zero Parsing Hacks

Predictable Structured JSON Contracts

Raw LLMs hallucinate syntax and break on model updates. Every RSFlowHub endpoint returns a validated top-level JSON envelope ({ success, data, telemetry }) that never breaks client parsers.

Sub-150ms Latency

0-DB Redis Dynamic Model Router

Our Redis-backed state engine routes incoming requests to the fastest, cheapest, healthy LLM (OpenAI, Claude, Gemini, DeepSeek) in sub-150ms with zero database latency in the hot path.

Zero Outage Downtime

3-State Circuit Breaker Failover

Automatic fault tolerance (CLOSED -> HALF-OPEN -> OPEN). If an upstream provider lags or experiences a 429/500 outage, traffic fails over instantaneously with 99.95% uptime.

One Billing Account

Single Master API Key & Wallet

Eliminate the headache of managing 5+ AI accounts, different billing cycles, and separate credit cards. One master X-API-Key and unified credit wallet in USD ($) or INR (₹).

pgvector RAG Built-In

Native Vector RAG & Knowledge Bases

Upload PDF, DOCX, or text data into Supabase pgvector with 768-dimensional cosine embeddings. Retrieve high-precision semantic search context for AI Chatbots in milliseconds.

Enterprise Grade

Enterprise Privacy & Zero Data Retention

Your request payloads and customer conversations are strictly ephemeral. Zero prompt caching, zero persistence, and zero customer data used for upstream model training.

Sub-150ms Dynamic Failover Manual Client-Side Retries Basic Fallback
Pre-Built Task Endpoints 0 (Prompt Eng. Required) 0 (Pass-through only)
Unified Wallet & Multi-Currency 5+ Credit Cards / Billing Rows USD Credit Cards Only
Native Vector RAG (pgvector) Requires External Vector DB No Vector Storage
Zero Prompt Retention Policy Vendor Specific Retention Varies by Proxy Host

Developer FAQ

Frequently Asked Questions

Everything you need to know about API keys, dynamic routing latency, credit billing, and data privacy.

Do I need separate OpenAI, Gemini, Claude, or DeepSeek API keys?

No. You only need a single RSFlowHub master API key. Dynamic model routing, fallback circuit breakers, provider API keys, and token cost settlements are handled transparently on our platform.

How does the 0-DB dynamic router achieve sub-150ms latency?

RSFlowHub utilizes an in-memory Redis state cache to check provider health and model latencies without querying disk databases during execution, ensuring sub-150ms routing overhead.

How does the 3-state circuit breaker handle upstream outages?

When an upstream AI provider experiences latency spikes or HTTP 429/500 errors, our circuit breaker trips from CLOSED to OPEN, automatically rerouting traffic to healthy alternative models without breaking your app.

Will response formats stay predictable across model version updates?

Yes. Every RSFlowHub endpoint returns a strict, validated top-level JSON response envelope ({ success: true, data: {...}, telemetry: {...} }). Your application parsing logic will never break when underlying models update.

How does credit deduction and pre-authorization billing work?

Every API call consumes credits based on operation complexity (typically 1 to 3 base credits). An atomic pre-authorization hold prevents overdrafts, and settlements occur atomically upon successful execution.

Does RSFlowHub store or train on my prompt data?

No. RSFlowHub operates on a strict zero-data-retention policy. Request payloads are processed in-memory and never persisted to disk or shared with third parties for LLM training.

How does RSFlowHub differ from direct provider APIs or generic proxies?

Unlike raw AI providers that require multiple keys and lack failover, and unlike generic proxies that merely pass raw text, RSFlowHub provides specialized, ready-to-use NLP APIs with guaranteed JSON contracts, RAG vector storage, and unified billing.

What happens if I exhaust my free 1,000 signup credits?

You can top up credits anytime starting from $1.50 (₹99) with no monthly commitments. Purchased credits never expire and work across all current and future endpoints.
