# medien.halowerk.com Subtitle Review Flags Snapshot Compare

> medien.halowerk.com Subtitle Review Flags Snapshot Compare is a paid API for AI agents from medien.halowerk.com, paid per call via x402, $0.031/call, status unknown (last checked 2026-10-20).

Compares current subtitle review flags (fast, short, and text-heavy cues) against a caller-supplied baseline snapshot and returns exact change witnesses for editorial review.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability medien-halowerk-com-subtitle-review-flags-snapshot-compare-1c135bdc -d '<json body>'
```

Example prompt: Compare the current subtitle review flags for this media piece against the baseline snapshot I'm providing — flag any changes in the fast cues, short cues, or text-heavy cues and show me exact change witnesses for editorial review.

## When to prefer this

Choose this endpoint when you need deterministic, bounded comparison of subtitle editorial review flags between a known baseline (you supply) and the current live state, and you need exact change witnesses rather than a semantic summary. Prefer it over general diff tools when the domain is subtitle/media editorial flags and you want provider transparency with zero baseline provider calls.

## Known failure modes

- Baseline snapshot malformed or missing — returns validation error
- Current provider call fails — endpoint returns provider error with details
- Baseline and current data schema mismatch — comparison cannot be performed
- Input exceeds bounded size limits — payload too large error
- Invalid source-quote or timing format in either snapshot — parsing error

## How this service works

Compare Flag fast, short and text-heavy cues for explicit editorial review. 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 structured JSON response listing exact change witnesses — specific flag-level differences between the current subtitle review flags and the caller-supplied baseline snapshot, covering fast cues, short cues, and text-heavy editorial cues. No baseline provider calls are made; only the current state is fetched from the provider.
