Transformations API
Transformations API
| Method | Path | Description |
|---|---|---|
GET | /api/transformations | List available transformation types |
POST | /api/transformations/preview | Preview a single transformation against sample data |
GET /api/transformations returns the registered node types from
app/engine/registry.py.
POST /api/transformations/preview runs one node's config against supplied sample
rows — this powers the editor's live preview without saving a run.
Full node metadata
GET /api/transformations returns only type names. For the complete node catalog
(labels, categories, handles, default config — including plugin-contributed
nodes), use GET /api/catalog/nodes.
