# Compare

GET https://api.agenttrunk.ai/v1/trunks/{trunkId}/contexts/{contextKey}/compare

Authorizes both revisions and returns their manifests, per-file statuses,
and one selected file preview. Target defaults to latest; base defaults to
the target's parent, or an empty snapshot for the first revision. The
returned IDs are immutable; use them for subsequent file selections.
UTF-8 previews verify file digests and are capped at 128000 bytes per side.
reason is null, too_large, binary, or too_complex. Omitted previews have
empty content and zero counts, which must not be displayed as no changes.
