## 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 sky-observations-identifier-crosswalk-audit-7e236fa9 -d '<json body>'
```

Example prompt: Audit the identifier crosswalk for these 5 sky observation rows against 5 mappings — the data class is public and nonpersonal metadata is confirmed — and tell me which identifiers have mismatched or unresolved aliases.

## When to prefer this

Choose this endpoint when you need to audit identifier alias consistency across pinned sky observation records in a structured, typed manner, particularly when working with public or synthetic celestial data and needing a verifiable crosswalk report without ownership or authenticity claims.

## Known failure modes

- Row or mapping count outside 1–32 range returns validation error
- Missing nonpersonalMetadata: true field causes rejection
- Invalid dataClass value (not 'public' or 'synthetic') causes schema error
- Mismatched row and mapping counts may result in incomplete crosswalk output
- Malformed pin structures in rows or mappings may produce null alias results

## How this service works

Check one-to-one aliases against every typed pin; identifier mapping does not establish ownership, rights or authenticity for sky frame/epoch/observer/method-pinned Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a structured audit report indicating which identifier pairs form valid one-to-one aliases, which mappings have conflicts or gaps, and the overall crosswalk consistency across the supplied sky observation rows and mappings — without certifying ownership, rights, or authenticity.
