How this service works
Compare Cross-reference subtitle cues with contained source words and flag label mismatch. against a bounded caller-supplied previous snapshot and return exact change witnesses. Baseline is caller supplied and is never authenticated as historical server output. Pure bounded timing/source-quote validation runs before payment. Exactly one current motor call, zero baseline provider calls. Full current provider disclosure retained; baseline is not submitted to the provider.
Output
A JSON response listing exact change witnesses: which subtitle cues have speaker label mismatches relative to the caller-supplied baseline snapshot, with details on the specific source words and labels that diverged. No baseline data is submitted to the underlying provider; only the current state is processed by the provider.
Example use cases
Subtitle QA before video publish
“I have my current subtitle file with speaker labels and a snapshot from yesterday's review pass — can you cross-reference them and tell me which cues have mismatched speaker attributions or changed source words before I publish?”
Localization speaker label audit
“We localized our video subtitles and I want to make sure no speaker cue labels got swapped during the process — compare this new version against the original snapshot and flag every mismatch.”
Post-edit subtitle drift detection
“After our editor made changes to the subtitle file, I need to verify the speaker labels still match the source words correctly — compare the edited version to the pre-edit snapshot and return every cue that changed or mismatches.”

Endpoint
POSThttps://medien.halowerk.com/v1/baumarkt/media/speaker-cue-crosswalk/snapshot-compare?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate speaker cue label consistency between two versions of a subtitle file and get a precise diff of mismatches, without submitting your historical baseline to any third-party provider. Ideal for QA pipelines where subtitle accuracy between edit passes must be verified before payment or publication.
Side effects
- Malformed or missing current cue data returns validation error
- Baseline snapshot format incompatible with current cue format
- No mismatches found returns empty change witness list
- Provider call fails for current media, returning provider error
- Snapshot too large exceeds bounded input limits
