| 3 | Mounted at /api/repos/... |
| 4 | |
| 5 | These are the canonical machine-readable repo endpoints. |
| 6 | The browser UI continues to live at /{owner}/{slug}/... for human-readable URLs. |
| 7 | |
| 8 | Endpoint surface: |
| 9 | GET /api/repos — list / search repos |
| 10 | POST /api/repos — create a repo |
| 11 | GET /api/repos/{repo_id} — get repo metadata |
| 12 | PATCH /api/repos/{repo_id} — update repo metadata |
| 13 | DELETE /api/repos/{repo_id} — soft-delete a repo |
| 14 | |
| 15 | GET /api/repos/{repo_id}/branches — list branches |
| 16 | GET /api/repos/{repo_id}/commits — list commits (paginated) |
| 17 | GET /api/repos/{repo_id}/commits/{commit_id} — single commit |
| 18 | |
| 19 | GET /api/repos/{repo_id}/objects/{object_id} — serve a binary object |
| 20 | |
| 21 | Wire-protocol endpoints live at /wire/repos/{repo_id}/... (separate router). |
