# Delete an owned input Asset and erase its bytes

DELETE https://api.morphiaone.ai/v1/assets/{asset_id}

Erases the bytes of an input asset the caller owns and keeps a tombstone; a
later read answers `404 ASSET_NOT_FOUND`. A job already admitted from the asset
keeps its own snapshot copy and is not affected; that copy is erased when the
job is deleted or its input retention lapses. A result asset is deleted only
together with its job (`409 ASSET_OWNED_BY_JOB`). Idempotent: an asset already
deleted, purged or expired answers `204`. Requires no product scope.
