## 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-medienwerk-subtitle-line-balance-snapshot-compare-8e5253a6 -d '<json body>'
```

Example prompt: Compare the subtitle line balance snapshots from my two media source versions — the original cut and the revised cut — and show me where the cue distribution has shifted between them.

## When to prefer this

Use this endpoint when you need to programmatically diff two timestamped subtitle line balance snapshots from bounded media sources — particularly useful in QA workflows, localization consistency checks, or accessibility audits where you need to detect cue distribution changes between two versions of the same content. Prefer this over manual review or generic diff tools when subtitle-domain semantics (cue timestamps, line balance metrics) are required in the comparison output.

## Known failure modes

- Missing or malformed snapshot reference returns 400 with validation error
- Snapshot source not found returns 404
- Mismatched snapshot formats or incompatible media sources return 422
- Payment not received or insufficient USDC balance returns 402
- Timeout if media sources are large or unavailable returns 504
