## 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-research-5ff72124
```

Example prompt: Can you pull the full provenance report for a 1952 Topps Mickey Mantle baseball card — I need the ownership history, any Art Loss Register flags, and whatever authenticity documentation is available before I make an offer?

## When to prefer this

Use this endpoint when a collector, appraiser, or investor agent needs to verify the legitimacy and ownership history of a collectible prior to purchase, sale, or appraisal — especially when Art Loss Register checks or authenticity documentation are required. Prefer this over general web search when structured provenance data, stolen-item registry verification, and documented chain of custody are needed in a single call.

## Known failure modes

- Item not found in provenance databases — returns empty or partial results
- Art Loss Register check unavailable for certain item categories
- Insufficient item details provided to identify the specific collectible
- External registry services temporarily unavailable — partial data returned
- Item description too vague to return accurate provenance chain

## How this service works

Provenance & ownership history check: research the chain of ownership, Art Loss Register / stolen-art checks, and authenticity documentation for art, antiques and memorabilia. Worldwide. For collector and appraiser agents.

## Output

A structured report containing the item's ownership history (chain of custody), Art Loss Register check results indicating whether the item has been flagged as stolen or missing, and any available authenticity documentation supporting the item's legitimacy
