# Planetary Measurements – Identifier Crosswalk Audit

> Planetary Measurements – Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035256/call, status unknown (last checked 2026-10-16).

Validates one-to-one alias mappings against every typed pin in supplied planetary measurement records, flagging mismatches without asserting ownership or authenticity.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 planetary-measurements-identifier-crosswalk-audit-1e834eb5 -d '<json body>'
```

Example prompt: Audit these 10 planetary measurement rows and their 10 alias mappings for identifier crosswalk consistency — the data is public and non-personal — and flag any pins where the one-to-one aliases don't match.

## When to prefer this

Choose this endpoint when you need to programmatically verify that identifier aliases in planetary or celestial measurement records correctly map one-to-one to every typed pin, especially as a pre-ingestion or QA step in data pipelines handling public or synthetic astronomical datasets. It is not a certification or ownership authority — use it strictly for alias consistency auditing.

## Known failure modes

- rows or mappings arrays exceed 32 items — request rejected
- mismatched array lengths between rows and mappings — validation error
- nonpersonalMetadata not set to true — request rejected
- dataClass not set to 'public' or 'synthetic' — enum validation error
- payment not provided or insufficient USDC — 402 response
- malformed row or mapping objects — schema validation failure

## How this service works

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

## Output

An audit report listing each row and mapping pair, indicating whether the alias correctly matches the typed pin, along with flags for any mismatches or inconsistencies found across the submitted planetary measurement records.
