## 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 collectablespulse-provenance-ownership-history-check-3ff3377b
```

Example prompt: Can you run a provenance and ownership history check on a Jean-Michel Basquiat painting titled 'Untitled 1982' — I need the full chain of custody, any Art Loss Register hits, and authenticity documentation before I make an offer?

## When to prefer this

Use this endpoint when an agent needs to perform acquisition due diligence on art, antiques, or memorabilia — specifically when ownership history, stolen-art screening (Art Loss Register), and authenticity documentation are required. Prefer this over a generic authentication check when the chain of custody and theft history are the primary concern, not just physical authenticity.

## Known failure modes

- Insufficient item details to identify the specific work — returns error requesting more descriptive input
- Item not found in known provenance databases — returns empty or partial results
- Art Loss Register query timeout — returns a partial report with a note on the incomplete check
- Ambiguous artist or item name matching multiple works — returns disambiguation prompt or multiple candidates

## How this service works

## Output

A provenance report including the item's chain of ownership, Art Loss Register / stolen-art check results, any red flags on theft or looting, and available authenticity documentation — structured for collector and appraiser due diligence.
