Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Compare the latest snapshot of the Baumarkt manufacturing supplier literal index against the previous one and show me what changed — which suppliers were added, removed, or modified.

## When to prefer this

Choose this endpoint when you need to programmatically detect and compare changes between two specific points-in-time snapshots of a Baumarkt-sector manufacturing supplier literal index. It is purpose-built for supplier catalog diff workflows in the hardware/DIY retail domain, unlike generic diff tools or broader procurement APIs.

## Known failure modes

- Missing or invalid snapshot identifiers result in a 400/422 error
- Snapshot not found returns an error indicating unavailable reference point
- Malformed request body causes a validation error
- Payment failure via x402 prevents endpoint access
- If both snapshots are identical, returns an empty diff with no changes noted
