## 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-events-venue-literal-index-snapshot-compare-a312452e -d '<json body>'
```

Example prompt: Compare these two snapshots of my events venue literal index and tell me exactly what changed — which venue entries were added, removed, or modified between the two versions.

## When to prefer this

Choose this endpoint when you need a precise, literal-vocabulary diff between two captured states of an events-venue index — especially for publication planning audits, compliance reviews, or monitoring drift in venue listing data. It is purpose-built for literal text comparison of venue index snapshots rather than semantic similarity or full-document diffing.

## Known failure modes

- Invalid or unreachable snapshot input URLs — returns error indicating fetch failure
- Snapshots too large or malformed — returns parsing error
- Identical snapshots — returns empty diff with no changes reported
- Unsupported content format — returns format error
- Payment failure via x402 — request is rejected before processing
