## 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 market-catalogues-identifier-crosswalk-audit-2f3de171 -d '<json body>'
```

Example prompt: Can you run a crosswalk audit on these 10 product catalogue identifier rows and their alias mappings to check if each one-to-one match holds — use the 'public' data class and confirm non-personal metadata only?

## When to prefer this

Choose this endpoint when you need to audit identifier alias consistency for public or synthetic product catalogue records across merchant, SKU, and revision dimensions, and do not require ownership verification or authenticity certification — it is a supplied-record analysis tool, not an independent certification service.

## Known failure modes

- Exceeds 32 rows or mappings limit — request rejected
- dataClass not set to 'public' or 'synthetic' — validation error
- nonpersonalMetadata not set to true — request rejected
- Malformed row or mapping objects — schema validation failure
- Empty rows or mappings array — minimum items constraint violation

## How this service works

Check one-to-one aliases against every typed pin; identifier mapping does not establish ownership, rights or authenticity for merchant/catalogue/SKU/revision-pinned public product Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns an audit report indicating whether each submitted identifier row and alias mapping pair satisfies the declared one-to-one crosswalk relationship, flagging mismatches or inconsistencies without asserting ownership, rights, or product authenticity.
