# Ephemeris Snapshots Identifier Crosswalk Audit

> Ephemeris Snapshots Identifier Crosswalk Audit is a paid API for AI agents from www.mahastrategies.com, paid per call via x402, $0.035244/call, status unknown (last checked 2026-10-20).

Audits one-to-one alias mappings for ephemeris identifier fields, checking that target, centre, frame, time-scale, correction, and kernel pins are consistently cross-referenced 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 ephemeris-snapshots-identifier-crosswalk-audit-eb16cc92 -d '<json body>'
```

Example prompt: Can you audit these 10 ephemeris snapshot rows and their identifier alias mappings — treat them as public, non-personal data — and tell me which aliases don't crosswalk consistently across the target, frame, and time-scale pins?

## When to prefer this

Choose this endpoint when you need to programmatically audit one-to-one alias consistency across ephemeris identifier fields (target, centre, frame, time-scale, correction, kernel) for up to 32 records at a time, and do not require ownership verification or authenticity certification — only supplied-record crosswalk analysis.

## Known failure modes

- rows or mappings arrays empty or exceed 32-item limit — validation error
- dataClass not set to 'public' or 'synthetic' — schema rejection
- nonpersonalMetadata not explicitly set to true — request rejected
- malformed or unparseable identifier strings in rows — audit may return partial results
- mismatched array lengths between rows and mappings — error or incomplete crosswalk

## How this service works

Check one-to-one aliases against every typed pin; identifier mapping does not establish ownership, rights or authenticity for target/centre/frame/time-scale/correction/kernel-pinned ephemeris Supplied-record analysis, not independent certification. Full contract at the free describe URL.

## Output

Returns a structured audit report indicating which alias mappings are consistent or inconsistent across the typed identifier pins (target, centre, frame, time-scale, correction, kernel) for each supplied row, without asserting ownership or authenticity of the ephemeris data.
