Evaluation Metric RSFlowHub API Raw LLM Prompts Legacy Regex / Rules
Response Structure Validated JSON envelope Unstructured markdown or chat format Brittle custom regex tuples
Setup Effort One POST request, no prompts Write and maintain prompts + output parsing Fast, but rule lists miss context and sarcasm
Pricing Model Flat 3 credit/request Volatile token-based billing High server maintenance overhead
Multi-Turn Hallucination Zero (Deterministic validators) Output format can drift between model versions No semantic AI intelligence
Developer Integration 3 lines cURL, PHP, JS, Python Complex prompt engineering & retry loop Fragile manual rule maintenance
