Developer Quickstart

Integrate in Minutes. Ship Without Breaks.

Call any RSFlowHub endpoint with a standard REST request from your favorite language. You get structured JSON back, with automatic model fallback and a request ID on every call for easy debugging.

Structured JSON Responses:
Fields like intent and confidence, not free text you have to clean up and parse.
Automatic Provider Fallback:
When an AI provider rate-limits or fails, the request is retried on a backup model.

Why Developers Build on RSFlowHub

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

One Response Format

Structured JSON You Can Parse

Every endpoint returns the same envelope: { success, request_id, data: { result }, meta }. Results are validated before they are returned, so your code works with fields, not free text.

4 AI Providers

Multi-Provider Model Routing

Requests run on models from OpenAI, Google Gemini, DeepSeek and xAI Grok. We pick and tune the model per task, so you never write or maintain prompts yourself.

Built-In Resilience

Automatic Provider Fallback

A circuit breaker tracks provider health. When a provider returns errors or rate limits, the request is retried on a backup model, so a single upstream outage does not take your feature down.

Simple Billing

One API Key, One Bill

Skip separate accounts, keys and invoices for every AI vendor. One RSFlowHub key, one credit balance, billed in USD ($) or INR (₹).

pgvector RAG

Built-In RAG Knowledge Bases

Upload documents or FAQ items, then search them semantically or ask questions with cited answers. Ideal for support bots and internal help centers.

Privacy First

Your Data Is Not Used for Training

RSFlowHub never uses your requests to train models. We log usage metadata for billing, and identical requests may be cached for up to 24 hours so repeats cost less.

Developer FAQ

Frequently Asked Questions

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

What is RSFlowHub?

RSFlowHub is a developer platform of ready-made AI APIs. Instead of writing prompts and parsing free text, you call an endpoint such as sentiment analysis, content moderation, translation or ticket triage and receive structured JSON. 29 endpoints are available with one API key.

Do I need my own OpenAI, Gemini or DeepSeek API keys?

No. One RSFlowHub API key covers every endpoint. Provider accounts, model selection, prompts, retries and token costs are handled on our side and billed to you as simple credits.

How fast are responses?

Most requests complete in 1 to 3 seconds, depending on input length and the AI model. Identical repeat requests are served from cache and return faster. We recommend a client timeout of 15 to 30 seconds for generation endpoints.

What happens if an AI provider has an outage?

A circuit breaker monitors each provider. When a provider returns errors or rate limits, requests are retried on a configured backup model, and you are not charged for failed calls.

What does an API response look like?

Every successful call returns { "success": true, "request_id": "req_...", "data": { "result": { ... } }, "meta": { "version": "v1", "timestamp": "..." } }. Errors use the same envelope with an error code and message, so one parser handles every endpoint.

How does pricing work?

Each call costs credits: simple calls start at 1 base credit, and generation endpoints add credits for longer inputs and outputs. The Free plan includes 100 credits per month plus 1,000 free requests on utility APIs (intent, sentiment, PII redaction and spam detection). Paid plans start at $6/month. Extra credit packs start at $2 and never expire.

Do you store my data or use it for training?

RSFlowHub does not use your requests or outputs to train AI models. Request text is sent to the selected AI provider only to produce the result. We log usage metadata such as character counts and credits for billing, and identical requests may be cached for up to 24 hours so repeat calls cost less.

Which languages and frameworks can I use?

Any language that can make an HTTPS POST request. The documentation includes copy-paste examples for cURL, PHP, Node.js and Python, and the endpoints work the same from Laravel, Express, Next.js, Django or a mobile backend.
