## 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-interview-career-literal-index-snapshot-compare-8e1efddc -d '<json body>'
```

Example prompt: Compare the two most recent snapshots of the interview-career literal keyword index from our bounded content source and show me what passages or keyword matches have changed between them.

## When to prefer this

Use this endpoint when you need to detect precise literal-keyword-level changes between two indexed states of interview or career content within a bounded source scope. Prefer this over full re-indexing when you already have prior snapshots and only need the delta, and over semantic search endpoints when exact literal vocabulary matching and change tracking is the goal.

## Known failure modes

- Invalid or missing snapshot identifiers returns an error
- Snapshot IDs outside the bounded caller scope returns a permission or not-found error
- Literal keyword list empty or malformed causes a validation error
- Source content unavailable at snapshot time may return incomplete diff
- Rate limit or payment failure via x402 returns a 402 response
