GET /downloadPresentationAsset

For most use cases, the slideless pull command handles this endpoint for you — it fetches the manifest and iterates over assets automatically.

When to use

You’re writing a tool that pulls a presentation owned by you or shared with you as a dev collaborator. The endpoint streams one content-addressed blob at a time; pair it with GET /getPresentationVersion to get the manifest (path → sha256 mapping) first.

Endpoint

GET https://europe-west1-slideless-ai.cloudfunctions.net/downloadPresentationAsset
    ?presentationId=<presentationId>
    &sha256=<hex64>
    [&version=<N>]

Authentication

Header	Required	Notes
`Authorization: Bearer <key>`	yes	`cko_` org key or `cka_` admin key.

The caller must be the owner or an active dev collaborator.

Query parameters

Param	Type	Required	Notes
`presentationId`	string	yes	The presentation ID.
`sha256`	string	yes	64 lowercase hex chars — the blob’s content hash from the manifest.
`version`	integer	no	Which version’s manifest to validate against. Default: `currentVersion`.

Response

200 OK streams the blob body. Content-Type matches the manifest entry. Supports HTTP Range requests (Accept-Ranges: bytes) — useful for large assets. The custom X-Slideless-Sha256 response header echoes the requested hash; the CLI uses it to confirm it got the blob it asked for.

Errors

Status	Code	Cause	Fix
401	`unauthenticated`	Missing or invalid API key	Authenticate via `slideless login`.
403	`permission-denied`	Not the owner or an active dev collaborator	Ask for an invite or verify the key owner.
404	`not-found`	`presentationId`, `version`, or `sha256` unknown	Double-check the manifest.
