Example prompt: Compare today's literal shortage discussion coverage in baumarkt logistics media against this snapshot I recorded last week, and show me exactly which passages or shortage-related phrases are new or changed.

## When to prefer this

Choose this endpoint when you need to detect exact literal-vocabulary changes in shortage-discussion media coverage for baumarkt/logistics topics between a known prior state (your own snapshot) and the current moment. It is ideal for audit trails, procurement monitoring, and change-detection workflows where semantic interpretation is not needed and exact quote-level change witnesses are required. Not suitable for semantic similarity, fuzzy matching, or authenticated historical diffing.

## Known failure modes

- Baseline snapshot format invalid or unparseable — returns error without provider call
- No changes detected between baseline and current — returns empty change witness set
- Current provider search returns no results for shortage-related literal terms — empty diff
- Baseline not authenticated as historical server output — accepted as-is per design, but caller bears risk of tampered baseline
- Payment of 0.031 USDC not completed — request rejected before processing
- Rate limiting or provider unavailability for current motor call

## How this service works

Compare Timestamped source search for shortage discussion wording; literal vocabulary only. 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 containing exact change witnesses — specific text passages and quoted phrases from current logistics/baumarkt shortage-discussion media that differ from the caller-supplied baseline snapshot, with timestamps and source attribution for each change detected.

## Response schema (JSON Schema)
