John O'Keefe 25ef0d12ba docs(kobo,koreader,collections): Beam WO5 batch 6 — 12 endpoints
Kobo emulation + KOReader calibre-compatible surface backfilled with
device-token auth; collections reorder + update_rule created.

Claude registry: 12 entries. kobo/koreader emulation endpoints all bind
arbitrary protocol POST bodies (markup/bookmark/gettests/sync-from-server,
koreader progress/bookmarks) — registered as AnyJSONObject, not bodyless as
first drafted. Initialization returns the library sync payload, not the init
response.

Contract correction in update_rule.md: the route is SetRuleEnabled ({enabled}
required -> {collection_id, is_smart}); Beam's draft invented rule-field
updates. Reordered response/status: {item_ids} -> {status: reordered}.

make test 9/9.

GET /api/sync/koreader/metadata/:uuid device-token koreader

Get Metadata

Get a book's stored progress and annotations for a KOReader device — the pull half of the device sync. The reference client calls this after linking a book via Resolve Book and navigates to the returned position.

Endpoint: GET /api/sync/koreader/metadata/:uuid Auth: Required (Device authentication — Authorization: Bearer {device_token})

Path Parameters

Parameter Type Required Description
uuid string (UUID) Yes Book UUID

Example Request

GET /api/sync/koreader/metadata/774641f9-317b-4087-8e04-53bb4392ae56
Authorization: Bearer {device_token}

Response (200 OK)

Progress Object

Field Type Description
percentage float Stored position as a book fraction.
koreader_xpointer string The stored canonical position converted back to a CRE xpointer (UTF-16 text().N offset). The device should navigate to this. Reflowable books only.
epubcfi string The stored canonical CFI, when the conversion to a CRE xpointer is unavailable. Fallback after koreader_xpointer.
character int Book-wide rune offset (internal currency).
chapter, chapter_progress int, float Chapter position when known.
page, total_pages int Fixed-layout page position — the canonical locator for image-based books (CFI/xpointer are omitted for them).

progress is null when the book has no stored progress.

The annotations object carries device-format highlights/bookmarks/notes synced from other clients; its presence depends on annotation sync being enabled.

Error Responses
