Get asset by ID

One asset's full record: the list row's fields plus image (type, pixel size, bytes, SHA-1 and the facts ingest derived), metadata (what exiftool read), takenAt and, for anything a job made, lineage. While the asset is PROCESSING its image facts are not measured yet.

USE THIS WHEN:

• Reading one asset's full record (image facts, metadata, lineage), typically once it is DONE
• Resolving a known asset ID

DO NOT USE WHEN:

• Listing assets → use GET /api/v1/assets
• Waiting for ingest to finish → POST /api/v1/assets/status polls a batch in one call
• You want the bytes → GET /api/v1/assets/{id}/content
