What this workflow does

This workflow has 56 nodes and runs when someone submits an n8n form (“Try LDX hub — 6 services in one workflow”). Along the way it connects Ldxhub (community).

How it runs

Trigger: When someone submits an n8n form (“Try LDX hub — 6 services in one workflow”).

  1. Route by Service (Switch): routes items into 6 branches
  2. StructFlow: Get Models (HTTP Request): calls an HTTP API
  3. AnalyzeDoc: Get Models (HTTP Request): calls an HTTP API
  4. RefineLoop: Get Models (HTTP Request): calls an HTTP API
  5. RenderOCR: Get Engines (HTTP Request): calls an HTTP API
  6. CastDoc: Get Engines (HTTP Request): calls an HTTP API
  7. ExtractDoc: Get Engines (HTTP Request): calls an HTTP API
  8. StructFlow: Derive Options (Edit Fields (Set)): sets 1 field: model_options
  9. AnalyzeDoc: Select Model (n8n Form): shows the next form page
  10. RefineLoop: Derive Options (Edit Fields (Set)): sets 1 field: model_options

…plus 45 more steps. See the full node list below.

Services it uses

  • Check that n8n-nodes-ldxhub is verified or supports 3.0 (used in ExtractDoc: Run, RenderOCR: Run, CastDoc: Run).
