Every guide and item has stable machine URLs on the same host as the human reader.
| Resource | Canonical path | File-style alias |
|---|---|---|
| Whole guide | /g/{slug}/gdf | /g/{slug}.gdf |
| One item | /g/{slug}/{item_id}/gdf | /g/{slug}/{item_id}.gdf |
| Human page | /g/{slug}/{legacy_id} | - |
Item ids: use GDF form item-701220 or legacy numeric 701220 (same item).
Query formats (guide-level only):
Each exported item includes metadata.co.guides.gdf_url, gdf_file_url, canonical_url, and api_url.
