# /api/v1/eas

Fetch the [file](https://docs.fylr.io/for-developers/system-data-types/file) renderings for several files at once. The file `ids` are passed as a JSON array in the query; the response is a map keyed by file `ID`. A file is shown if the user holds `RIGHT_ASSET_SHOW` or `RIGHT_ASSET_DOWNLOAD` on the original or on at least one of its versions. There is no blanket login gate: an unauthenticated request is served via the `deep_link` system user if deep linking is enabled. Use `GET /eas/{fileId}` to address a single file.

Differs from easydb 5: easydb 5 requires an authenticated user on `GET /eas` ("The user must be authenticated."); **fylr** has no login gate here — a missing token is served as the anonymous `deep_link` user, and a denied request is `403` (`InsufficientRights`), never `401`.

### `GET /eas/{fileId}` — Get information about a file. The file is shown if the caller holds `RIGHT_ASSET_SHOW` or `RIGHT_ASSET_DOWNLOAD` on the original or any version.

### `POST /eas/{fileId}` — Change information about a file. The caller must be allowed to produce the file (its uploader, or a user with write access to a linked object).
