## 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 reading-plans-identifier-crosswalk-audit-0c24ab61 -d '<json body>'
```

Example prompt: Can you audit the identifier crosswalk for these 10 reading plan rows to check if all the typed pin aliases map one-to-one correctly? The data is synthetic and contains only non-personal metadata.

## When to prefer this

Use this endpoint when you need to verify that identifier aliases in reading plan records map correctly one-to-one across typed pins (library, plan, work, edition, revision), without needing ownership or authenticity certification. Prefer this over generic record-sequence or source-binding endpoints when the specific task is crosswalk alias auditing for bibliographic/reading-plan identifier data.

## Known failure modes

- rows array exceeds 32 items — request rejected
- mappings array exceeds 32 items — request rejected
- dataClass value not in enum ['public','synthetic'] — validation error
- nonpersonalMetadata not set to true — request rejected
- mismatched row/mapping counts causing incomplete audit results
- malformed pin data in rows causing partial audit output

## How this service works

Check one-to-one aliases against every typed pin; identifier mapping does not establish ownership, rights or authenticity for library/plan/work/edition/revision-pinned reading Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a per-row crosswalk audit result indicating whether each typed pin has a valid one-to-one alias match against the provided mappings. Results reflect supplied-record analysis only and do not certify ownership, rights, or authenticity for any library, plan, work, edition, or revision pin.
