## 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 halowerk-punctuation-edit-index-snapshot-compare-7ce6281c -d '<json body>'
```

Example prompt: Compare the punctuation edit index snapshots for the baumarkt media source — I need to see what changed between the two most recent indexed versions, specifically which punctuation edits were added or removed.

## When to prefer this

Use this endpoint when you need to precisely compare two versioned punctuation edit indexes from HALOWERK medienwerk's baumarkt media pipeline — particularly when tracking how punctuation corrections have evolved between processing runs or auditing editorial changes in indexed media transcripts. Prefer this over generic diff tools when the source data is already indexed in HALOWERK's snapshot system.

## Known failure modes

- Invalid or missing snapshot identifiers returns an error response
- Snapshot not found if the referenced index version does not exist
- Malformed request body causes a 400-level error
- Payment failure via x402 protocol blocks the request
- Comparison against an out-of-bounds or unbounded snapshot reference fails validation
