## 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 procurement-notices-identifier-crosswalk-audit-0b0a7b05 -d '<json body>'
```

Example prompt: Can you audit the identifier crosswalk for these 5 procurement notice rows and their mappings to check if the aliases are consistent — using public data class and nonpersonal metadata only?

## When to prefer this

Use this endpoint when you need to audit whether procurement notice identifiers alias correctly to each other across buyer, notice, kind, jurisdiction, and revision dimensions, and you want a structured crosswalk report without needing independent certification. Prefer this over general data validation tools when working specifically with procurement notice identifier mappings in public or synthetic datasets of up to 32 records.

## Known failure modes

- Input rows or mappings array empty or exceeds 32-item limit — validation error returned
- dataClass enum value not 'public' or 'synthetic' — schema rejection
- nonpersonalMetadata not set to true (const constraint violated) — request rejected
- Malformed identifier formats in rows or mappings — audit may flag as unknown or return parsing errors
- Mismatched array lengths between rows and mappings may produce incomplete crosswalk results

## How this service works

Check one-to-one aliases against every typed pin; identifier mapping does not establish ownership, rights or authenticity for buyer/notice/kind/jurisdiction/revision-pinned procurement Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns an audit report of identifier alias consistency across the supplied procurement notice rows and mappings, flagging mismatches, unknown states, or contradictory one-to-one alias pairings for each typed pin combination. Does not certify ownership, authenticity, or rights.
