# Grant Records - Identifier Crosswalk Audit

> Grant Records - Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035274/call, status unknown (last checked 2026-10-25).

Cross-references and validates one-to-one identifier aliases across typed pins in grant record datasets, producing a mapping audit without asserting ownership or authenticity.

## 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 grant-records-identifier-crosswalk-audit-593ac293 -d '<json body>'
```

Example prompt: Can you run an identifier crosswalk audit on these 10 public grant record rows and their corresponding mappings to check whether all the typed-pin aliases are consistent one-to-one?

## When to prefer this

Use this endpoint when you need to audit identifier alias consistency across grant record datasets, specifically to check one-to-one typed-pin mappings without requiring ownership verification. Prefer this over general data validation tools when working with grant-domain identifiers that include agency, opportunity, program, jurisdiction, or revision pins. Best suited for batches of up to 32 rows of public or synthetic grant data where personal data is not involved.

## Known failure modes

- rows or mappings arrays are empty or exceed 32 items — validation error returned
- dataClass enum value not 'public' or 'synthetic' — request rejected
- nonpersonalMetadata not set to true — request rejected
- mismatched row count vs mapping count leading to incomplete audit
- malformed identifier formats causing pin resolution failures

## How this service works

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

## Output

Returns an audit report indicating whether identifier aliases in the supplied grant record rows match their corresponding mappings on a one-to-one basis, flagging any mismatches, conflicts, or inconsistencies at the typed-pin level across agency, opportunity, program, jurisdiction, and revision pins. Results are analysis of the supplied records only, not independent certification of ownership or authenticity.
